Ingredients for applesauce sour cream coffee cake
Eight servings of pure comfort—moist crumb, buttery streusel, and caramelized apple swirl await.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown preferred |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Unsweetened Applesauce 🍎 | 1 cup | Unsweetened, unsalted |
| Sour Cream 🥛 | ½ cup | Full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Ground Cinnamon 🍃 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla preferred |
| Brown Sugar 🍚 | ½ cup | Packed, for streusel |
| Old-Fashioned Oats 🌾 | ½ cup | Blended into flour |
| Granny Smith Apples 🍎 | 2 medium | Peeled, finely diced |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The applesauce is non-negotiable—it keeps this cake moist for days without tasting artificial. Mott's unsweetened is my go-to, but any brand labeled 'unsweetened' works. The sour cream? Full-fat only (trust me on this)—it's what gives this cake that signature tender crumb. For the apples, Granny Smith is ideal—they hold their shape during baking and add a bright tang. If you can't find them, Honeycrisp works too, but they'll get softer. The cinnamon and nutmeg? Freshly ground from whole spices if possible—Penzeys sells them pre-ground if you're short on time.
No sour cream? Greek yogurt at half the quantity gets you close, though the texture won't be identical. Applesauce shortage? Unsweetened applesauce from a can works, but if you've got mashed banana, that's a game-changer—swap it 1:1. The oats in the streusel can be quick oats if that's what you've got, but old-fashioned gives better texture. For the butter, if you've only got salted, reduce the added salt by 0.25 tsp. And if you're feeling fancy, add 0.5 tsp of cardamom to the streusel—it pairs beautifully with the apples.
This cake stays fresh for 4-5 days at room temperature, wrapped tightly in foil. For longer storage, freeze portions for up to 3 months—just thaw at room temperature before serving. The streusel topping gets crispier the next day, so I always make a double batch. Pro tip: Brush the warm cake with simple syrup (equal parts sugar and water, heated) before serving—it keeps the crumb moist and adds a subtle gloss. Store leftovers in an airtight container with a slice of bread to absorb moisture.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this trick—just fold the applesauce and sour cream right into the dry ingredients. No creaming butter and sugar, no waiting for room temp butter, no fuss. The sour cream keeps it tender, and the applesauce makes the batter glide together like butter.
- Caramel-Kissed Magic: That first bite? Warm, spiced cake with a moist crumb, then the buttery streusel topping gives you little pockets of caramelized sugar. Honestly, it’s the kind of flavor that makes you pause mid-sip of coffee and go, “Wait, I need more.”
- Breakfast or Dessert: Serve it with a pat of butter and a drizzle of honey for a weekend brunch that feels special. Or slice it up for a picnic—it’s sturdy enough to pack but still melts in your mouth. (Yes, even on a Tuesday night.)
- Half the Cost, Double the Joy: Applesauce replaces butter, and sour cream adds richness without breaking the bank. A single batch feeds six, and leftovers reheat beautifully—toss a slice in the toaster or microwave for a quick snack. My wallet and my taste buds win.
Step-by-step instructions for applesauce sour cream coffee cake
Here's how to create a tender crumb with perfect swirls and a buttery crust that'll disappear in minutes.
Prepare the Apple Filling and Blend the Cake Base
Start by peeling and finely dicing the 2 medium Granny Smith apples. Toss them with the 1 cup unsweetened applesauce, 1 tbsp freshly squeezed lemon juice, and 1 tbsp vanilla extract in a small bowl. Set aside—this bright filling will keep your cake moist and flavorful.
In a separate large bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Sift this mixture directly into the bowl to prevent lumps. This dry blend forms the foundation of our tender crumb.
Mix Wet Ingredients for a Light Batter
In another large bowl, cream together the 1 cup cold unsalted butter and 1.5 cups granulated sugar until light and fluffy—about 3-4 minutes. This step is crucial for creating that signature airy texture. Add the 2 whole room-temperature eggs one at a time, mixing well after each addition.
Stir in the 0.5 cup full-fat sour cream and the prepared apple mixture. The batter should be thick but pourable. If it looks too thick, add 1-2 tablespoons of milk (though our recipe doesn't call for it, this is a pro tip). The sour cream adds richness while keeping the cake moist.
Combine Wet and Dry Ingredients
Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until combined. Avoid overmixing—you should still see some flour streaks. This careful combination ensures a tender crumb rather than a dense cake. Set half of the batter aside for the top layer.
For the streusel topping, blend the 0.5 cup old-fashioned oats with the remaining 2.5 cups flour in a food processor until finely ground. In a small bowl, mix this oat-flour blend with 0.5 cup packed brown sugar, 1 tbsp vanilla extract, and 2 tbsp cold butter until crumbly. This will create our signature crunchy topping.
Assemble and Bake to Golden Perfection
Preheat your oven to 350°F. Grease and flour a 9x13-inch baking pan. Spread half of the cake batter evenly in the pan. Spoon the apple filling over the batter, then top with the remaining batter. Sprinkle the streusel mixture evenly over the top—press down lightly so it sticks.
Bake for 45-50 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should be pulling away slightly from the pan. Real talk: don't overbake—this cake is best when just set in the center. Let cool in the pan for 15 minutes before transferring to a wire rack.
Serve Warm with Your Favorite Coffee
Slice while still warm for that perfect balance of tender crumb and buttery streusel. The applesauce filling should be visible through the cake layers, adding natural sweetness that complements the spiced streusel. Serve with a dollop of whipped cream or extra sour cream for that classic coffee cake experience.
Pro Tips For Making Applesauce Sour Cream Coffee Cake
- Mix Butter Cold: DESCRIPTION: Cut that unsalted butter into tiny cubes—pea-sized, almost powdery—and fold it into the dry ingredients last. I used to melt it first, thinking it’d save time, but the cake turned out dense and greasy. Cold butter creates pockets of steam that make the crumb light and flaky.
- Whisk Sour Cream First: DESCRIPTION: Before adding it to the batter, give the sour cream a quick whisk to break up any lumps—especially if it’s thick or full-fat. I learned this after a batch turned out gummy; the unwhisked sour cream didn’t distribute evenly. A 10-second stir makes a real difference.
- Don’t Overmix the Batter: DESCRIPTION: Stop folding in the applesauce the second it’s just combined—no streaks, no overworking. I’ve ruined batches by mixing until the batter looked "perfect," only to end up with a tough, chewy cake. The goal is a marbled effect, not a smooth paste.
- Bake Until Golden, Not Just Set: DESCRIPTION: Pull the cake when the edges are deep golden brown and a toothpick comes out with moist crumbs, not wet batter. Mine used to look done too soon—underbaked centers make it gummy. A few extra minutes at 350°F (even if it smells done) guarantees the right texture.
Essential equipment for great applesauce sour cream coffee cake
Baking Pan Essentials
For this recipe, a 9x13-inch baking pan is non-negotiable—it's the perfect size for even baking and that classic coffee cake shape. I recommend a heavy-duty stainless steel pan like Nordic Ware Natural Aluminum Half-Sheet Pan because it distributes heat evenly and prevents burning.
If you don't have one, a glass pan works too, but reduce your baking time by about 5-7 minutes since glass retains more heat. 🧊
Mixing Tools
A stand mixer with a paddle attachment makes creaming butter and sugar effortless, but a hand mixer or even a sturdy wooden spoon will work if you're mixing by hand.
For the streusel topping, a food processor is ideal for grinding oats into fine flour, but you can also pulse them in a blender or even crush them with a rolling pin. Pro tip: Use a spatula with a flexible edge to gently fold the batter—it minimizes overmixing. 🥄
Measuring Precision
Accurate measurements are key, especially for the dry ingredients like flour and spices. Invest in a digital kitchen scale for the most precise results, but if you're measuring by volume, use the spoon-and-level method—don't scoop directly from the bag.
For the applesauce and sour cream, a liquid measuring cup ensures you get the right consistency. I swear by the OXO Good Grips set—they're durable and easy to read. 📏
Butter Tools
Cold, cubed butter is essential for the streusel topping to create that perfect crumbly texture. Use a microplane or grater to cube 1 cup of cold unsalted butter evenly—this ensures it melts uniformly during baking.
If you're short on time, a sharp chef's knife works too, but avoid pressing too hard to prevent warming the butter. For the wet ingredients, a rubber spatula helps scrape every last bit of that delicious batter from the bowl. 🧈
Cooling and Serving
A wire cooling rack is a must for letting your coffee cake cool evenly without soggy bottoms. I love the Willow Wooden Cooling Racks because they're sturdy and breathable. For serving, a sharp serrated knife (like the Mercer Culinary Genesis) makes clean slices that showcase the apple swirl beautifully.
Don’t forget a damp towel—wipe down the knife between slices to prevent crumbs. 🍴
Optional Extras
While not essential, a pastry brush comes in handy for brushing the warm cake with simple syrup or melted butter to keep it moist. For garnishing, a small offset spatula helps spread whipped cream or caramel drizzle evenly.
If you're feeling fancy, a piping bag with a star tip can create elegant swirls of extra sour cream or cream cheese frosting. 🎨

Frequently asked questions
Can I substitute applesauce with something else if I don't have it?
Yes! For a 1:1 swap, use unsweetened applesauce from a can or mashed banana (though banana adds a slightly different flavor). If you're out of both, try pumpkin puree (reduce other liquids by 2 tbsp to maintain moisture balance). The key is keeping the batter tender—these substitutes all work because they replace fat and add natural sweetness.
Why does my coffee cake turn out dense instead of tender?
Overmixing is the #1 culprit! Stop folding the batter when you still see flour streaks. Also, ensure your butter is cold for the streusel and eggs are room temperature. For extra fluffiness, whip the egg whites separately and fold them in at the end. The sour cream and applesauce combo should prevent dryness if measured correctly.
How do I make this recipe gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill. Add 1 tsp xanthan gum to help bind the crumb. For the streusel, use a certified gluten-free oat blend (like GFJ's). Note: The texture will be slightly denser, but still delicious. Always check labels—some gluten-free flours contain xanthan gum already.
Can I bake this in a different pan size?
For a 9-inch round pan, reduce baking time by 10-15 minutes (check at 35-40 minutes). For a 8x8-inch pan, bake 30-35 minutes. The cake will be taller, so watch closely for doneness. If using a glass pan, reduce temperature by 25°F to prevent over-browning. Always grease pans thoroughly for easy removal.
What's the best way to reheat slices?
For maximum freshness, warm slices in a 350°F oven for 5-8 minutes with a sprinkle of water on a baking sheet. For quick reheating, use a toaster oven at 300°F for 3-4 minutes. Microwave in 10-second bursts (covered with a damp paper towel) to avoid drying. The streusel topping gets crispy again when reheated—perfect for serving with coffee!
