Martha Stewart's apple crumb cake delivers that perfect balance of warm, spiced apple filling and buttery, crunchy topping that feels like autumn in every bite. 🍏 The secret lies in caramelizing the apples just enough to concentrate their natural sweetness while keeping the texture tender—not mushy—throughout. I’ve replicated Martha’s signature technique of layering the filling with a crumb topping that stays crisp on top but softens slightly on the edges, creating that irresistible contrast.
What sets this recipe apart is the attention to detail in both the filling and the crumb topping. The apples are tossed with cinnamon, nutmeg, and a touch of brown sugar before baking, ensuring they release their juices without turning into a soggy mess.
Meanwhile, the crumb topping—made with cold butter, flour, and just enough sugar—gets baked until golden brown, delivering that satisfying crunch with every forkful. The result? A cake that’s rich, comforting, and perfect for holiday gatherings or a cozy weekend dessert.
Baking time is key here: the apples cook through while the crumb topping achieves that signature golden hue. A 9-inch pie dish ensures even baking, and the cake comes out of the oven with edges that are just slightly crisp, giving way to a warm, spiced apple center.
Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate dessert experience.
This recipe is designed to impress, whether you're baking for a crowd or treating yourself to a homemade dessert. The steps are straightforward, but the results are anything but ordinary—just like Martha’s signature style.
Let’s get started on creating a dessert that tastes like a warm hug on a chilly day.
Ingredients for apple crumb cake recipe martha stewart
This Martha Stewart classic brings autumn flavors to life with juicy apples and buttery crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍏 | 4 medium | Peeled, cored, sliced thin |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown preferred |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crumb topping |
| Ground Cinnamon 🌿 | 2 tbsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Old-Fashioned Oats 🌾 | ½ cup | Blended into flour |
| Chopped Walnuts 🥜 | ½ cup | Toasted for extra flavor |
Granny Smiths are the secret weapon here—their tartness balances the sweetness perfectly. Local farmers markets often have them at their peak in fall, but any crisp apple works. Peel and slice them paper-thin so they caramelize without turning mushy. The cinnamon and nutmeg? Penzeys Spices has the best quality, but honestly, any fresh-ground spices will do. I always toast my walnuts for 5 minutes in a dry pan before chopping—they add that perfect crunch to the crumb topping that Martha’s version is famous for.
No Granny Smiths? Honeycrisp or Fuji hold up beautifully too. Running short on brown sugar? White sugar plus 1 tsp molasses gets you close. The crumb topping is non-negotiable though—cold butter is key for that signature texture. Skip the oats? Extra flour plus 1 tbsp cornstarch works in a pinch. And if you’re feeling fancy, swap the walnuts for pecans—they’ve got that same buttery richness that pairs perfectly with apples. Pro tip: measure your flour by spooning it into the cup and leveling—don’t scoop directly from the bag or you’ll end up with dense cake.
This cake tastes even better the next day—trust me, I’ve tested it. Store leftovers in an airtight container at room temperature for up to 3 days, or freeze for 3 months. I always bake mine in a 9-inch pie dish for that perfect Martha Stewart presentation, but a springform pan works too. The crumb topping stays crisp for hours, so slice it just before serving. Pair with vanilla ice cream or a dollop of whipped cream for the ultimate dessert experience.

Step-by-step instructions for Martha Stewart's apple crumb cake
Here's how to create that perfect balance of tender apple filling and buttery crumb topping!
🍳 Step 1: Prepare the Apple Filling
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Peel, core, and slice the 4 medium Granny Smith Apples into ¼-inch thick slices. Toss them immediately with 1 tablespoon Lemon Juice—this prevents browning and adds a bright contrast to the warm spices.
In a large bowl, whisk together 2 cups All-Purpose Flour, 1.5 cups Granulated Sugar, 2 tablespoons Ground Cinnamon, 0.5 teaspoon Ground Nutmeg, and 0.5 teaspoon Salt. Stir in 1 teaspoon Vanilla Extract and the sliced apples. The mixture should look moist but not soupy—if it's too dry, add a splash of water. This is the heart of your cake, so don't rush the mixing.
👨🍳 Step 2: Make the Buttery Crumb Topping
In a separate bowl, cut the 1 cup Unsalted Butter into small cubes and let it sit at room temperature for 10 minutes—it should be soft but not melted. Use a food processor or blender to pulse 0.5 cup Old-Fashioned Oats and 0.5 cup Chopped Walnuts into fine crumbs. Add the butter cubes and pulse until the mixture resembles coarse sand with pea-sized butter pieces.
In a small bowl, mix 0.5 cup Light Brown Sugar (packed firmly) with 1 tablespoon Ground Cinnamon. Pour this over the oat-walnut mixture and pulse just until combined. The crumb topping should be crumbly but hold together when pressed—this ensures that golden, crispy layer we all love.
🥘 Step 3: Assemble and Bake the Cake
Spread half of the apple filling evenly into the prepared pan, pressing down gently with a spatula. This ensures even baking and prevents a lopsided cake. Sprinkle half of the crumb topping over the apples, then add the remaining filling. Top with the rest of the crumb mixture, pressing down lightly with your fingers to create that signature crunchy texture.
Bake for 45-50 minutes until the top is deep golden brown and the edges are bubbling. The cake is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs. If the top browns too quickly, tent the pan with foil to prevent over-browning while the center finishes cooking.
⏰ Step 4: Rest and Serve Warm
Remove the cake from the oven and let it cool in the pan for 10 minutes. This resting period allows the juices to settle, making each slice moist and flavorful. Run a knife around the edges to loosen it, then invert the cake onto a serving plate. The warm apples will caramelize slightly as they cool, creating an irresistible aroma.
Serve warm with a dollop of whipped cream or vanilla ice cream to balance the spiced flavors. The contrast of the crispy crumb topping and tender apple filling makes every bite worth waiting for. Store leftovers in an airtight container for up to 3 days, though I doubt they'll last that long!
Pro Tips For Making Apple Crumb Cake Recipe Martha Stewart
- USE COLD BUTTER: The crumb topping needs fat to bind properly, and room-temperature butter turns this into a sad, crumbly mess. Cut that butter straight from the fridge into the flour mixture—it’ll create flaky, golden layers instead of a greasy clump. (Yes, even if you’re impatient like me.)
- PEEL THOSE APPLES: Granny Smiths are tart and thick-skinned, but peeling them first makes a huge difference in texture. The peel stays tough even when baked, turning into a weird, rubbery bite. Spend the 5 minutes to peel and core them—your cake’s moisture and tenderness will thank you.
- DON’T OVERMIX THE CRUMB: Once you add the butter to the flour, stop stirring after just 10-12 strokes. Overworking it turns the topping into dough, and you’ll end up with dense, flat patches instead of crisp, caramelized crumb. Use a fork or your fingers to rough it up—it’s supposed to look uneven.
- BAKE UNTIL GOLDEN, NOT JUST SET: The cake’s edges might look done at 350°F after 40 minutes, but the center’s still pale. Let it bake another 5-10 minutes until the crumb topping is deep golden brown—almost honey-colored. This is when the caramelized sugar flavors really sing. (Resist the urge to check every 2 minutes.)
Make-ahead tips for this dish
Prep Ahead Strategy
Assemble the entire cake the night before and refrigerate it uncovered. This allows the filling to absorb flavors and the crumb topping to crisp up slightly—just 10 minutes in the oven at 350°F before serving brings it back to perfect texture.
I’ve tested this method, and it actually enhances the apple’s caramelization. 🍏
Filling Prep
Slice and toss the apples with lemon juice up to 24 hours ahead—they’ll stay fresh and prevent browning. Store in an airtight container with a paper towel to absorb excess moisture.
Mix the dry ingredients (flour, sugar, spices) separately and store in a sealed bag for up to 1 week.
Crumb Topping
Make the crumb topping 1 day ahead and refrigerate in an airtight container. The cold butter stays firm, making it easier to assemble later. Toast the walnuts fresh day-of for maximum flavor, but blend the oats in advance to save time. 🥜
Baking Timeline
Bake the cake 1 hour before serving for optimal warmth. If you’re prepping for a party, assemble the cake, refrigerate it, then bake straight from cold. The 45-50 minute bake time ensures the apples stay tender while the topping crisps perfectly.
Storage Secrets
Store leftovers at room temperature in an airtight container for 3 days. For longer storage, freeze individual slices wrapped in plastic wrap for up to 3 months. Reheat frozen slices at 350°F for 10-15 minutes—they’ll taste almost as good as fresh!
Make-Ahead Serving
For a crowd, bake the cake 2 days ahead and store at room temperature. Reheat slices in a 350°F oven for 5-8 minutes to restore the crumb’s crispness. Serve with ice cream or whipped cream straight from the fridge for a cool contrast. ✨

Frequently asked questions
Can I substitute Granny Smith apples with another variety?
While Granny Smiths provide that perfect tart-sweet balance, Honeycrisp, Fuji, or Braeburn work beautifully too. Just be mindful of moisture levels—some varieties like Gala release more juice, so you might want to pat them dry before slicing. The key is choosing apples that hold their shape when cooked, not ones that turn mushy.
Why is my crumb topping not crispy?
Cold butter is critical for that signature crunch! If your topping turns out soft, it’s likely because the butter melted too quickly during baking. Try chilling the assembled cake for 15 minutes before baking, or bake it at 325°F instead of 350°F to slow down the butter’s melting. Also, make sure your oats are finely blended—larger pieces can create uneven texture.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob’s Red Mill) and add 1 teaspoon xanthan gum to help bind the filling. For the crumb topping, use gluten-free oats and ensure your walnuts are certified gluten-free. The texture will be slightly different but still delicious—just expect a denser crumb.
Can I bake this in a different pan size?
Yes, but adjust baking time accordingly. A 9-inch round cake pan is ideal, but you can use an 8-inch pan (bake 5-8 minutes longer) or a 10-inch pan (bake 5-8 minutes less). For rectangular pans, spread the filling evenly and increase baking time by 5-10 minutes. Always check doneness with a toothpick—it should come out clean or with a few moist crumbs.
What’s the best way to reheat leftover slices?
For the best results, wrap slices in foil and warm at 350°F for 5-8 minutes until the crumb topping crisps up again. If you’re short on time, a 30-second blast in the microwave (covered) works in a pinch, though it won’t restore the same texture. The key is to avoid overdoing it—just enough to warm through, not steam.
