Desserts
This apple cake recipe in an 8x8 pan delivers the perfect balance of tender crumb and spiced streusel—every slice reveals moist layers topped with a caramelized, cinnamon-kissed crown. The secret lies in a simple batter enriched with applesauce and a streusel that stays crunchy without turning to sand.
I developed this version after years of baking apples into cakes, and it never fails to disappear within hours of coming out of the oven.
The beauty of this recipe is its simplicity: just 15 ingredients and one bowl for mixing. The batter stays light and fluffy thanks to a touch of baking powder, while the streusel—made with rolled oats, brown sugar, and warm spices—adds texture and depth.
Baking in an 8x8 pan ensures even cooking, with edges that stay tender and a center that’s just set.
What you’ll end up with is a cake that’s moist throughout, with juicy apple pieces peeking through the streusel and a scent that fills the kitchen with warm apple-cinnamon aromas. The streusel crown caramelizes beautifully, creating pockets of buttery crunch that contrast perfectly with the soft cake beneath.
This is the kind of dessert that feels like a hug—comforting, familiar, and impossible to resist.
Serve warm with vanilla ice cream or whipped cream, or let it cool slightly for clean slices. The recipe scales easily for a crowd, and the leftovers reheat beautifully. Here’s how to make it—step by step—so you can experience the magic for yourself.
Ingredients for apple cake recipe 8x8 pan
Fifteen simple ingredients for an 8x8 pan cake with moist layers and caramelized streusel crown.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| Unsalted Butter 🧈 | 1 cup | Room temperature, cubed |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Applesauce 🍎 | 1 cup | Unsweetened, unscented |
| Vanilla Extract 🍯 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free recommended |
| Ground Cinnamon 🌿 | 1 tbsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| McIntosh Apples 🍎 | 2 medium | Peeled, diced (about 2 cups) |
| Rolled Oats 🌾 | 1 cup | Old-fashioned, not quick |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Granulated White Sugar 🍚 | ¼ cup | For streusel topping |

The apples are the heart of this cake, so McIntosh or Honeycrisp work best—they hold their shape while staying tender. Walmart or Kroger usually carry these varieties year-round, but local orchards in fall are unbeatable. Peel and dice them into even 1/2-inch pieces for consistent baking. The rolled oats for the streusel should be old-fashioned, not quick oats—they create the perfect crunch without turning to mush. I always buy mine in bulk at Costco to save money, but any grocery store has them. For the spices, Penzeys sells pre-ground cinnamon and nutmeg that's more aromatic than the supermarket stuff, but regular grocery store brands work fine if they're fresh.
No McIntosh apples? Gala or Fuji hold up well too—just dice them slightly smaller. Running short on brown sugar? White sugar plus 1/4 tsp molasses mimics the moisture. The streusel can be made ahead and stored in the fridge for up to 3 days—just sprinkle it on top before baking. Need to skip the streusel? A dusting of powdered sugar works in a pinch, though it lacks that caramelized crunch. The baking powder is crucial—aluminum-free gives the best rise, but regular works if that's what you've got. For extra moisture, add 1 tbsp sour cream to the batter, but it's not required.
This cake keeps beautifully for 4 days at room temperature wrapped in foil, or 1 week in the fridge. Reheat slices in the microwave for 15-20 seconds to restore that warm, gooey texture. The streusel topping stays crisp for 2 days at room temperature, but the cake itself is best enjoyed fresh. I always make a double batch—one for the pan, one for mini muffins. The leftovers freeze well for 3 months if wrapped tightly in plastic wrap and foil. Just thaw overnight in the fridge before serving.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when I’m too tired to cream butter and sugar. Just fold the dry ingredients into melted butter—no standing over a bowl, no extra bowls. The eggs bind it all together like magic, and the texture stays tender without a lick of effort.
- Caramelized Core: That brown sugar? It’s the secret weapon. The apples soften just enough to release their juice, which soaks into the cake while the edges stay lightly crisp. Honestly, the first bite is always the best—warm, sticky, and packed with that buttery-apple punch.
- Lunchbox Hero: Between us, this cake is my go-to for school lunches or office snacks. Slice it into squares, wrap in parchment, and it stays fresh for days. (Yes, even on a Tuesday night when I’m prepping for the week.) The 8x8 pan makes perfect portions—no weird leftovers crowding the fridge.
- Budget-Friendly Luxury: I use this recipe when I want something special but don’t want to break the bank. Butter and eggs are the stars, but the flour and sugars stretch far enough to feed a crowd. The best part? It tastes like you spent hours baking, not 30 minutes and $10.
Step-by-step instructions for apple cake in 8x8 pan
Here's how to create a perfectly balanced apple cake with tender layers and a crunchy spiced streusel topping.
Prepare the Cake Batter
Preheat your oven to 350°F and grease an 8x8-inch baking pan with butter or line it with parchment paper. In a large mixing bowl, combine the 2.5 cups all-purpose flour, 2 teaspoons baking powder, 1 tablespoon ground cinnamon, 0.5 teaspoon salt, and 0.5 teaspoon ground nutmeg. Whisk these dry ingredients together until evenly distributed - this ensures your cake will rise properly.
In a separate bowl, cream together the 1 cup unsalted butter (at room temperature), 1.5 cups granulated sugar, and 0.5 cup packed brown sugar using an electric mixer on medium speed for 3-4 minutes until light and fluffy. This step is crucial for creating that tender, moist texture we're aiming for. The mixture should be pale and nearly tripled in volume.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon vanilla extract and 1 cup applesauce. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Be careful not to overmix - you should still see small flour streaks in the batter. Fold in the 2 cups diced McIntosh apples gently with a spatula, ensuring they're evenly distributed throughout.
Bake the Cake Layer
Pour the prepared batter into your greased 8x8-inch pan and smooth the top with a spatula. Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The edges should be golden brown while the center remains slightly springy to the touch.
I like to check for doneness at the 30-minute mark - this is when most cakes are ready. If the top is browning too quickly, tent the pan with aluminum foil to prevent over-browning while allowing the center to finish cooking. The cake should have a gentle rise and pull away slightly from the sides of the pan when done.
Prepare the Streusel Topping
While the cake bakes, prepare the streusel topping in a medium bowl. Combine the 1 cup rolled oats, 0.25 cup granulated white sugar, 0.25 cup packed light brown sugar, and the remaining 1 tablespoon ground cinnamon. Mix these dry ingredients thoroughly to create an even distribution of spices throughout.
Cut the 1 cup unsalted butter (from the remaining amount) into small cubes and add them to the dry mixture. Use your fingers or a pastry cutter to work the butter into the oats until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture is perfect for creating that signature crunchy topping that contrasts beautifully with the moist cake layers.
Add Streusel and Finish Baking
Once the cake layer is done baking, immediately sprinkle the streusel mixture evenly over the top. You want to distribute it fairly evenly, leaving about ½-inch border around the edges of the pan. This allows the cake to continue baking while the streusel gets crispy without burning.
Return the cake to the oven and bake for an additional 15-20 minutes, or until the streusel is golden brown and crispy to the touch. The total baking time should be about 50-60 minutes from start to finish. You'll know it's done when the streusel has developed a deep caramel color and smells irresistibly spiced.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. This brief cooling period helps set the cake structure. Then carefully transfer the cake to a wire rack to cool completely. I've found that letting it cool completely prevents the streusel from becoming soggy when slicing.
Once fully cooled, slice into 8 equal squares for serving. Each piece should reveal the moist, tender cake layers beneath the crispy, spiced streusel topping. For best results, serve at room temperature - this allows the flavors to fully develop and the textures to contrast perfectly. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days.
Pro Tips For Making Apple Cake Recipe 8x8 Pan
- Use Room-Temp Butter: I learned this the hard way—cold butter makes for a cake that’s dry as yesterday’s bread. Take that butter out of the fridge 30 minutes before mixing, or even better, let it sit in a warm spot while you prep the apples. The batter will be smoother, and the crumb won’t turn out dense.
- Don’t Overmix the Batter: After burning three batches with a tough, chewy texture, I finally realized I was beating the heck out of the batter. Mix the wet and dry ingredients just until combined—lumps are fine, but don’t drag that mixer around like you’re trying to win a race. Overmixing develops gluten, and this cake needs tender, not tough.
- Grease That Pan: I know, I know—you’re in a hurry. But skip the parchment paper in an 8x8 pan, and you’ll end up with a cake stuck like glue. Use 1 tablespoon of softened butter, rub it around, then sprinkle in a handful of flour and tap out the excess. This isn’t the prettiest method, but it’s the tastiest—no tearing, no mess.
- Bake Until the Center Springs Back: Your cake might look done at 30 minutes, but resist the urge to pull it out early. Insert a toothpick—if it comes out with a few moist crumbs (not wet batter), it’s ready. If you take it out too soon, the middle will sink like a lead balloon. Sounds weird, but it works: let it bake until that toothpick test is clean or just slightly sticky.
Dietary considerations for this recipe
Gluten-Free Adaptation
Swap the 2.5 cups all-purpose flour for a 1:1 gluten-free baking flour blend like King Arthur Measure for Measure—it mimics the texture perfectly. Add 1 extra teaspoon xanthan gum to the dry ingredients to replicate gluten’s binding properties.
Reduce the 1 cup applesauce to ½ cup to prevent excess moisture, and increase the 1 cup butter to 1 ¼ cups for richness. Bake at 325°F instead of 350°F to avoid over-browning. 💪
Dairy-Free Options
Replace the 1 cup unsalted butter with 1 cup dairy-free butter like Miyoko’s or Earth Balance—both work beautifully. For the streusel, use 1 cup coconut oil (solid) instead of butter, though it adds a subtle coconut flavor.
The cake stays moist without dairy, and the streusel remains crispy. Just ensure all other ingredients are dairy-free, including any vanilla extract. ✨
Vegan Variations
For a fully vegan version, use 1 cup flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) and 1 cup applesauce as the only "egg" substitute. Replace the 1 cup butter with 1 cup vegan butter or ½ cup melted coconut oil (cooled).
Add 1 tsp apple cider vinegar to the batter for lift. The streusel can stay dairy-free with coconut oil, but it’ll be slightly softer. 🌱
Lower Sugar Swaps
Reduce the 1.5 cups granulated sugar and 0.5 cup brown sugar to 1 cup total (split evenly between white and brown). Use ½ cup unsweetened applesauce (already in the recipe) to offset the sugar reduction.
The cake stays tender, and the streusel can use ½ cup sugar total with 1 tbsp maple syrup for moisture. Monitor baking time closely—lower sugar means slightly faster cooking. 💛
Nut-Free Streusel
Skip the 1 cup rolled oats and replace with 1 cup crushed cornflakes or 1 cup shredded coconut (unsweetened). For extra crunch, add ½ cup crushed graham crackers (check for nut-free brands like Annie’s).
The texture stays crispy, and it’s perfect for those with nut allergies. Just toast the cornflakes lightly before mixing to enhance flavor. 🌾
Allergen-Friendly Tips
Always check labels for hidden allergens—Penzeys spices are typically safe, but some brands add fillers. For egg-free baking, use 1 tbsp ground flaxseed + 3 tbsp water per egg.
If avoiding apples, substitute with 2 cups diced pear or 1 ½ cups mashed banana (adjust sugar accordingly). The cake’s moisture balance adapts well to these swaps! 🍎
Nutrition facts
Frequently asked questions
Can I use any apples in this recipe?
For best results, stick with McIntosh, Honeycrisp, or Gala apples—they hold their shape while staying tender. Avoid overly soft varieties like Red Delicious, as they'll turn mushy during baking. If you have to use what's available, dice them slightly smaller (1/4-inch pieces) and pat them dry with a paper towel to remove excess moisture.
Why does my cake sink in the middle?
This usually happens from overmixing the batter or opening the oven too soon. Mix just until combined (small flour streaks should remain) and avoid peeking at the cake during the first 30 minutes of baking. The baking powder needs time to work—if the oven runs hot, tent with foil after 25 minutes to prevent over-browning.
Can I make this cake ahead of time?
Bake it 1 day ahead and store it at room temperature wrapped in foil. For longer storage (up to 5 days), refrigerate the whole cake in an airtight container. Reheat individual slices in the microwave for 15-20 seconds to restore that warm, gooey texture—just don't reheat the whole cake at once.
How do I adjust for a 9x9 pan?
Use the same recipe but increase baking time by 5-10 minutes—the thicker pan takes longer to cook through. Reduce the oven temperature to 325°F to prevent over-browning. The cake will be slightly taller, so check doneness with a toothpick after 45 minutes.
What's the best way to serve this cake?
Warm slices pair perfectly with vanilla ice cream or whipped cream, but it's equally delicious at room temperature. For a restaurant-style touch, dust with powdered sugar or drizzle with caramel sauce. The streusel stays crispy for 2 days at room temperature, so serve it fresh!
