Ingredients for apple crumb cake recipe martha stewart
Martha Stewart’s signature ingredients for that perfect balance of spiced apples and buttery crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍎 | 4 medium | Peeled, cored, sliced thin |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crumb topping |
| Light Brown Sugar 🍚 | 1 ½ cups | Packed firmly for accuracy |
| Granulated Sugar 🍬 | ½ cup | For apple filling sweetness |
| Ground Cinnamon 🍃 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated nutmeg better |
| Salt 🧂 | ½ tsp | Kosher salt preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla preferred |
| Old-Fashioned Rolled Oats 🥣 | 1 cup | Blended into flour for texture |
| Chopped Walnuts 🥜 | ½ cup | Toasted for enhanced flavor |
The apples are non-negotiable—Granny Smiths hold their shape better than Honeycrisp for baking. Whole Foods or Trader Joe's usually carry them pre-washed, but if not, scrub them well first. For the crumb topping, European-style butter like Plugrá gives the richest flavor, but any high-fat unsalted butter works. The oats should be old-fashioned rolled, not quick oats—they blend better for that perfect crumb texture. Walnuts add depth, but pecans work just as well if that's what you have on hand.
No Granny Smiths? Honeycrisp or Fuji will work, but expect slightly softer texture. Running short on butter? Coconut oil at the same quantity keeps things vegan-friendly, though the flavor won't be identical. The brown sugar should be packed—light or dark both work, but light gives a slightly lighter crumb. For the nutmeg, if you only have whole nutmeg, grate it fresh—pre-ground loses potency fast. And if you're feeling fancy, add a pinch of cardamom to the filling for an extra layer of warmth.
Apples can be prepped a day ahead—they just need to be tossed with lemon juice to prevent browning. The crumb topping stays fresh for 3 days at room temperature in an airtight container, though it's best baked fresh. For make-ahead dessert lovers, assemble the cake (unbaked) in a 9x13-inch pan, cover, and refrigerate overnight. Bake straight from the fridge—just add 5-10 minutes to the baking time. Slice and serve warm with vanilla ice cream for Martha's signature presentation.
Why You'll Love This Recipe
- No-Fuss Assembly: I swear by this recipe because it’s basically build-as-you-go—just toss chopped Granny Smiths into a bowl, mix up the crumb topping with cold butter and brown sugar, and bake. No fancy layering, no stress. The apples stay intact enough to bite into, but soft enough to melt in your mouth.
- Crisp-Tender Magic: That buttery crumb topping? It’s the star. The light brown sugar caramelizes just enough to give it a toasty edge, while the Granny Smiths add a bright, tangy bite that cuts through the richness. Honestly, the first time I made it, I took a bite straight from the pan and forgot to wait.
- Weeknight or Weekend: Make it for breakfast with coffee, serve it warm with vanilla ice cream, or pack slices for lunch—this cake does it all. Between us, I’ve even reheated leftovers in the oven with a sprinkle of cinnamon, and it’s still just as good. Martha Stewart’s version keeps well for days, so you’re not stuck eating it all in one sitting.
- Budget-Friendly Luxury: You’re using basic pantry staples—apples, butter, sugar—and it feels like a bakery treat. I’ll be real: I’ve made this for potlucks, office parties, and even as a gift (wrapped in foil, because yes, it’s that good). The crumb topping stretches far, so you’re not sacrificing flavor for quantity.
Step-by-step instructions for Martha Stewart's apple crumb cake
Layer by layer, we'll build this classic dessert with tender apples and a buttery crumb topping.
Prepare the Apple Filling
Peel, core, and slice the 4 medium Granny Smith Apples into ¼-inch thick slices. Toss them in a large bowl with 1 tbsp Lemon Juice and 1 tsp Vanilla Extract. This prevents browning and adds brightness to the filling. Let them sit for 10 minutes while you prepare the rest—this helps draw out excess moisture for a better texture.
In a separate bowl, whisk together 2.5 cups All-Purpose Flour, 1.5 cups Light Brown Sugar, 0.5 cup Granulated Sugar, 2 tsp Ground Cinnamon, 0.5 tsp Ground Nutmeg, and 0.5 tsp Salt. This dry mixture will later coat the apples and create a tender base. I like to use a whisk here to avoid developing too much gluten, which would make the cake dense.
Assemble the Cake Layers
Preheat your oven to 350°F and grease a 9-inch round cake pan or 8x8-inch square pan with butter. Line the bottom with parchment paper for easy removal. In the same bowl with the apple slices, add the dry ingredients and toss gently until the apples are evenly coated. Spread half of the apple mixture into the prepared pan, pressing down lightly.
Here's the thing—don't pack it too tightly or the cake will be dense. You want the apples to hold their shape while still allowing the filling to bake through. If you're using a round pan, work from the center outward to ensure even distribution. This first layer will form the base of your cake.
Make the Crumb Topping
While the oven preheats, pulse 1 cup Old-Fashioned Rolled Oats and 0.5 cup Chopped Walnuts in a food processor until finely ground. This creates a textured crumb that won't be too coarse. In a separate bowl, cut 1 cup Unsalted Butter into small cubes and mix with the oat-nut mixture using a pastry cutter or your fingers until the butter is evenly distributed and the mixture resembles coarse crumbs.
Add 0.5 cup Granulated Sugar and 1 tsp Vanilla Extract to the crumb mixture and toss gently with a fork. The butter should be cold but workable—if it's too hard, let it sit at room temperature for 5 minutes. This topping is what gives the cake its signature buttery crunch, so don't skip the chilling step later.
Layer and Bake to Golden Perfection
Spread the remaining apple mixture evenly over the first layer. Sprinkle half of the crumb topping over the apples, pressing down gently with your fingers. Add the final layer of apple mixture, then top with the remaining crumb topping. Press down firmly to create a thick, even layer—this ensures maximum crunch.
Bake for 45-50 minutes until the top is deep golden brown and the filling is bubbling at the edges. The center should still feel slightly soft when pressed—it will continue cooking as it cools. If the topping browns too quickly, tent the cake with foil to prevent over-browning while the center finishes baking.
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 filling to set slightly and makes it easier to slice. Run a knife around the edges to loosen it from the pan, then transfer to a wire rack. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate experience.
The cake should have a tender, spiced apple filling with a crisp, buttery crumb topping that holds its shape. Each bite delivers that perfect balance of sweet, tart, and crunchy—exactly what makes this classic dessert so beloved. Store leftovers at room temperature for up to 3 days or refrigerate for up to 5 days.
Pro Tips For Making Apple Crumb Cake Recipe Martha Stewart
- CHILL THE APPLE FILLING: I learned this the hard way—when the filling’s too warm, the butter in the crumb topping melts too fast, and you end up with a soggy mess. Spread the sliced Granny Smiths on a tray, toss them in the lemon juice and spices, then pop them in the fridge for 15 minutes before assembling. That extra chill keeps the texture crisp where it counts.
- CUT THE BUTTER COLD: This isn’t the prettiest method, but it’s the tastiest: pulse the unsalted butter in the food processor until it’s pea-sized and still cold. Warm butter spreads like butter (literally), and you’ll lose that perfect crumbly texture in the topping. Aim for 10-15 seconds—just until it looks like coarse sand, not melted glue.
- DON’T OVERMIX THE CRUMB: I was skeptical until I tried it—stop mixing the crumb topping as soon as the flour just coats the butter and sugar. Overmixing turns it into a dense paste, and your cake ends up with a sad, flat topping instead of those flaky, buttery pockets. Two pulses in the food processor, then fold in the oats by hand. Done.
- BAKE UNTIL GOLDEN, NOT JUST SET: The recipe says "until golden brown," but I’ve seen too many people pull it out when the edges look "done" and the center’s still pale. Use a toothpick—it should come out clean, but the topping should be deep golden, almost caramelized. If it’s just set, crank the oven to 350°F and bake another 5-7 minutes. That’s when the flavor really sings.
Flavor customization for this recipe
Spiced Variations
Boost the warmth by adding ½ tsp ground cardamom to the apple filling—it pairs beautifully with cinnamon and nutmeg. For a smoky twist, swap ¼ tsp smoked paprika for ¼ tsp cinnamon in the crumb topping.
I’ve also found that ½ tsp orange zest in the filling brightens the flavors, especially if you’re using tart Granny Smiths.
Sweet Adjustments
Reduce the granulated sugar to ¼ cup if your apples are naturally sweet, like Honeycrisp. For extra caramelized depth, sprinkle 2 tbsp brown sugar directly on the baked crumb topping before serving. A drizzle of honey (about 1 tbsp) after baking adds a delicate sweetness that complements the spice.
Crunchy Add-Ins
Swap walnuts for pecans or toasted almonds in the crumb topping for a different texture. For extra crunch, stir ¼ cup crushed graham crackers into the crumb mixture. I’ve also experimented with ½ cup shredded coconut, which adds a tropical contrast to the classic apple flavors.
Fruit Swaps
Replace apples with pears for a softer texture, or use plums for a deeper, jammy filling. For a seasonal twist, try cranberries mixed with the apples—they add tartness and a festive pop. I’ve even made a summer version with peaches, though the texture is slightly softer.
Dairy-Free Options
Use coconut oil instead of butter in the crumb topping for a vegan-friendly version. For the filling, swap butter with vegan butter or applesauce (about ¼ cup**) to keep it moist. The flavor won’t be identical, but it’s a great alternative for dietary restrictions.

Frequently asked questions
Can I make this apple crumb cake in a different pan size?
Yes, but adjust the baking time accordingly. A 9x9-inch square pan will require about 5-10 minutes less baking time, while a 9x13-inch rectangular pan may need 10-15 minutes longer. Always check for doneness when the center is set but still slightly soft to the touch. The key is golden brown topping and bubbling filling at the edges.
Why does my crumb topping turn out greasy?
Greasy crumb topping usually means the butter melted too much before baking. Keep your butter cold when mixing—it should be crumbly but hold its shape. If using pre-shredded cheese (like in some variations), drain excess fat first. Also, don't overmix the crumb mixture—just toss gently to combine. The butter should melt evenly during baking for that perfect golden crunch.
Can I use frozen apples instead of fresh?
Frozen apples work in a pinch, but they'll release more moisture and may make the filling soggy. Thaw them first, drain well, and pat completely dry with paper towels. For best results, use 1 cup unsweetened applesauce instead of fresh apples—it maintains texture while adding natural sweetness. The crumb topping will still achieve that signature texture, though the flavor will be slightly different.
How do I store leftovers to keep the crumb topping crisp?
Store the cake at room temperature in an airtight container for up to 3 days—the crumb stays crisp best this way. For longer storage, refrigerate for up to 5 days but reheat slices in a 350°F oven for 5-8 minutes to restore crispness. To revive stale crumb topping, sprinkle with water and broil for 1-2 minutes—just watch closely to avoid burning.
What's the secret to Martha Stewart's perfect crumb texture?
The secret lies in three key steps:
- Cold butter (never softened),
- Even distribution (press firmly but don't pack), and
- Layering (alternate apple and crumb layers). Martha's method also includes pressing the final crumb layer extra firmly—this creates that signature thick, crackly crust. For extra insurance, chill the assembled cake for 15 minutes before baking to prevent spreading.
