Martha Stewart's Apple Crumb Cake Recipe: Warm Spice and Nutty Streusel Magic

Martha Stewart's apple crumb cake recipe delivers the perfect balance of tender cake and buttery, nutty streusel topping that becomes irresistibly crisp. The secret lies in a precise butter-to-flour ratio for the crumb topping—this isn't just any streusel, but one that develops a golden, crackly crust while maintaining just enough softness to melt in your mouth. I've perfected this version over years of baking, ensuring the apples stay juicy and aromatic without turning the cake into a soggy mess.

What sets this recipe apart is Martha Stewart's signature technique of baking powder (not baking soda) in the cake batter, which creates a lighter, more tender crumb while still achieving that classic dome shape. The spice blend—cinnamon, nutmeg, and a touch of allspice—infuses every bite with warm, comforting flavors that pair beautifully with the sweet-tart apples. You'll want to make a double batch because this cake disappears faster than you can say "second slice."

The magic happens when the hot cake emerges from the oven, its edges caramelized and the crumb topping shattering into perfect, buttery pieces. This isn't just dessert—it's an experience that transforms any gathering into something special. The combination of tender cake, juicy apples, and that irresistible crumb topping makes it impossible to eat just one piece.

Whether you're baking for a holiday brunch or simply craving a comforting treat, this apple crumb cake delivers restaurant-quality results with minimal effort. The best part? It reheats beautifully, making it perfect for meal prep or taking to potlucks. Let's get baking!

These 15 ingredients create Martha's legendary crumb cake—tender cake meets buttery, nutty streusel perfection.

The butter in the crumb topping is non-negotiable—this is where the magic happens. European-style butter (like Plugrá) has higher fat content, which gives that irresistible crackly crust. If you're in a pinch, Land O'Lakes unsalted works fine, but don't use salted. The walnuts? Toast them first—5 minutes in a dry pan until fragrant. That nutty aroma is what sets this apart from regular streusel. For the apples, Honeycrisp or Granny Smith are ideal—they hold their shape while staying juicy. If you can't find those, Fuji or Braeburn work too. Peel and slice them about ¼-inch thick, then toss with lemon juice to keep them bright.

No baking powder? Substitute with 1.5 tsp baking soda plus 1.5 tsp cream of tartar, but the texture won't be quite the same. Running short on walnuts? Pecans or hazelnuts work beautifully—just toast them first. The oats are key for texture, but if you're out, crushed graham crackers can stand in (use the same amount). For the apples, canned pie apples in a pinch—just drain well and pat dry. The spice blend is crucial: cinnamon is the star, but that touch of allspice adds depth that store-bought mixes miss. Pro tip: Mix the dry crumb ingredients first—it's easier to combine with the butter later.

The cake keeps beautifully—3-4 days at room temperature covered loosely, or 1 week in the fridge. For the ultimate treat, reheat slices wrapped in foil in a 350°F oven for 5-7 minutes. The crumb topping gets even more irresistible that way. Freeze the whole cake (unbaked or baked) for up to 3 months—just thaw overnight in the fridge. I always make a double batch because this disappears fast. Store leftovers in an airtight container with a paper towel on top to keep the crumb from getting soggy.

Step-by-step instructions for Martha Stewart's apple crumb cake

This classic dessert combines tender apple cake with a buttery, nutty streusel topping—here's how to nail it every time.

Peel, core, and slice the 4 whole medium apples into ¼-inch thick slices. Toss them in a large bowl with the 1 tablespoon lemon juice to prevent browning. This step is crucial—it preserves the apples' freshness and brightens their natural sweetness. Arrange the apple slices in a single layer in a 9-inch square baking dish, slightly overlapping them. The lemon juice also helps balance the apples' natural tartness, which pairs beautifully with the warm spices in the cake.

Save any leftover lemon juice—it's perfect for sprinkling over the finished cake before serving. The acidity cuts through the richness of the butter and sugar, creating a perfect flavor balance. If you have extra, mix it with a little water and a pinch of sugar for a quick glaze.

In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 1.5 teaspoons baking powder, 0.5 teaspoon salt, 1 tablespoon ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.25 teaspoon ground allspice. Sifting these dry ingredients first ensures a light, airy texture for the cake. Set this mixture aside for now—it's the foundation of our tender crumb.

In a separate bowl, beat the 2 whole large eggs until just combined, then whisk in the 1 cup milk, 1 tablespoon vanilla extract, 1.5 cups granulated sugar, and 1.5 cups light brown sugar. The eggs and sugars should create a smooth, slightly thick mixture. This is where the cake's moisture and sweetness come from, so don't rush this step—properly incorporating the sugars ensures even distribution throughout the batter.

Gradually add the dry ingredients to the wet mixture, stirring just until combined. Be careful not to overmix—you want to maintain a light, fluffy texture. Pour this batter evenly over the apple slices in the baking dish, spreading it gently with a spatula to ensure the apples are fully coated. This step is all about balance: the batter should soak into the apples slightly but still leave room for the streusel topping to shine.

Here's a pro tip: If you notice the batter is too thick, add 1-2 tablespoons of milk to loosen it. The goal is a smooth, pourable consistency that will create a moist cake without being soggy. Once poured, let the batter sit for 5 minutes—this allows the apples to absorb some of the liquid, preventing a watery center when baking.

In a medium bowl, cut the 1 cup unsalted butter into small cubes and mix it with the 1 cup old-fashioned rolled oats, 0.5 cup chopped walnuts, 1 tablespoon ground cinnamon, 0.5 teaspoon salt, and 0.5 teaspoon ground nutmeg. Use your fingers or a fork to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture is key—it creates a crispy, crunchy topping that contrasts perfectly with the soft cake beneath.

Sprinkle the streusel evenly over the batter-covered apples, pressing down gently to ensure good contact. The streusel should cover about 80% of the surface, leaving some cake exposed for color and texture variation. This topping isn't just decorative—it's what gives this cake its signature crunch and depth of flavor. For extra richness, you could even add 1-2 tablespoons of brown sugar to the streusel mixture, but the recipe's already perfectly balanced as written.

Preheat your oven to 350°F and bake the cake for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The edges should pull away slightly from the baking dish, indicating the cake has set properly. If you notice the streusel browning too quickly, tent the dish with aluminum foil to prevent over-browning while the cake continues to cook underneath.

Here's where patience pays off: Let the cake cool in the pan for 15 minutes before transferring it to a wire rack to cool completely. This resting period allows the juices to redistribute, ensuring each bite is moist and flavorful. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream—this cake is at its best when freshly baked, with that perfect contrast of warm cake and cool topping.
