Martha Stewart's Apple Crumb Cake Recipe: Warm Spice Streusel Over Tart Fruit Layers

Martha Stewart's apple crumb cake delivers the perfect balance of tart apple layers and warm, spiced streusel topping—every bite is a cozy hug in cake form.

The secret lies in baking the apples first to concentrate their natural sweetness, then topping them with a buttery, cinnamon-kissed crumb that stays perfectly crisp.

This recipe has become a holiday staple in my kitchen, and I’ve perfected it through years of baking trials (and a few too many taste tests).

The magic happens in two stages: first, tender apples simmered with just enough sugar to enhance their flavor without overpowering it, then a streusel topping that bakes to a golden, crunchy blanket.

Unlike traditional crumb cakes, Martha’s version uses a mix of brown sugar and butter for depth, while a pinch of nutmeg adds warmth that lingers long after the last bite. The result is a dessert that’s rustic yet elegant—ideal for brunch, holiday gatherings, or a simple weekend treat.

With a 350°F oven and 50 minutes of baking time (including the initial apple prep), this recipe is simpler than it sounds. The apples release their juices, creating a moist yet sturdy base, while the streusel topping stays delightfully crumbly.

No fancy equipment is needed—just a standard cake pan and a little patience for the streusel to develop its signature texture. The aroma alone will have everyone gathering around the kitchen.

Once you try this version, you’ll understand why it’s a classic. The apples stay tender but hold their shape, and the streusel delivers that satisfying crunch in every forkful.

Serve it warm with vanilla ice cream or a dollop of whipped cream for the full experience. Here’s how to make it—step by step, just like Martha would.

Eight ingredients for the apples, seven for the streusel—simple but spectacular.

Granny Smith apples are non-negotiable here—their tartness balances the sweetness perfectly. Buy them firm and shiny, not mealy. I always grab mine from Whole Foods or the organic section at Kroger—they hold up better during prep. The brown sugar? Light brown is key—it adds that caramel depth. If you can't find light brown, mix regular granulated with a touch of molasses. For the butter, Plugrá or Land O'Lakes are my go-tos—just make sure it's cold when you measure it for that perfect streusel texture.

No Granny Smiths? Fuji or Honeycrisp work in a pinch, but they're sweeter, so reduce the sugar by 2 tbsp. Short on brown sugar? White sugar plus 1 tsp molasses gets you close. The oats can be quick or rolled—Trader Joe's quick oats are my secret weapon for extra crunch. No vanilla extract? Vanilla bean paste works too, just use half the amount. For the cinnamon, the difference between ground and cassia is huge—Penzeys or McCormick ground cinnamon are worth the splurge. And if you're feeling fancy, toast the oats for 5 minutes before mixing—they'll smell like autumn in your kitchen.

The apples release juices, so line your pan with parchment paper for easy removal. Store any leftover streusel mix in an airtight container for up to 2 weeks—it's perfect for topping yogurt or oatmeal. The cake itself keeps well for 3 days at room temperature, but I always make a double batch because it disappears fast. Wrap it tightly in foil if you're saving it for more than a day—keeps the streusel from getting soggy. And trust me, the second day is even better—everything melds together perfectly.

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

Here's how to create this perfect balance of tender cake and buttery spice streusel.

Peel, core, and slice the 4 medium Granny Smith Apples into ¼-inch thick rounds. Toss them immediately with 0.5 cup Granulated Sugar, 2 tbsp Lemon Juice, and 1 tsp Cinnamon in a large bowl. Let them sit for 10 minutes while you prepare the rest—this helps draw out their juices and softens them slightly.

The tartness of Granny Smiths pairs beautifully with the warm spices, but don't skip the lemon juice. It brightens the flavor and prevents the apples from turning brown during prep. You'll want the slices to be uniform in thickness so they cook evenly throughout the cake.

In a medium bowl, whisk together 1 cup All-Purpose Flour, 0.5 tsp Baking Powder, 0.25 tsp Salt, and 1 tbsp Ground Cinnamon. In a separate large bowl, combine 0.75 cup Unsalted Butter (softened but not melted) with 0.75 cup Light Brown Sugar and mix until light and fluffy. Add 0.5 tsp Vanilla Extract and beat for another 30 seconds. Gradually add the dry ingredients to the wet mixture, mixing just until combined.

Don't overmix here—the goal is to create a tender cake layer, not a dense one. You should still see small flour streaks in the batter. The brown sugar adds moisture and depth, while the cinnamon will complement the apples beautifully. Keep the butter slightly cool for a lighter texture in the final cake.

In a small bowl, mix 0.5 cup Old-Fashioned Oats, 1 tbsp Ground Cinnamon, 0.25 tsp Ground Nutmeg, and the remaining 0.25 tsp Salt. Cut in the 0.75 cup Unsalted Butter (still cold) using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture is crucial for that perfect crumbly topping.

The nutmeg adds a warm, earthy note that pairs wonderfully with the cinnamon and apples. Don't pulse this mixture in a food processor—you want some texture to hold the streusel together while still allowing it to crisp beautifully. The cold butter ensures it stays crumbly rather than turning into a paste.

Preheat your oven to 350°F. In a 9-inch springform pan (or similar size), spread half of the apple mixture evenly on the bottom. Pour the cake batter over the apples, then arrange the remaining apple slices on top. Finally, sprinkle the streusel topping evenly over everything, pressing down gently with your fingers.

Bake for 45-50 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should pull away slightly from the pan, and the streusel should be crisp but not burned. If the top browns too quickly, tent loosely with foil after 30 minutes to prevent over-browning.

Let the cake cool in the pan for 15 minutes, then release the springform and transfer to a wire rack. Serve warm—this is when the flavors are at their peak. The contrast of warm spiced cake with cool vanilla ice cream makes this dessert truly special.

The cake should be moist but not soggy, with tender cake layers and a crisp, buttery streusel that's just sweet enough to balance the tart apples. Each bite should deliver that perfect combination of textures and flavors that makes this recipe a classic.

Health benefits of this dish

Fiber-Rich Fruit Base

Granny Smith apples provide a surprising 4 grams of fiber per serving—about 15% of your daily needs—thanks to their natural pectin content. This fiber keeps you feeling full longer, helping stabilize blood sugar levels after dessert.

The apple slices also contain vitamin C and potassium, which support immune function and heart health. 🍎

Whole Grain Crunch

The ½ cup old-fashioned oats in the streusel topping add 3 grams of soluble fiber per serving, promoting healthy digestion. Oats also contain beta-glucan, a compound that helps lower cholesterol by binding to bile acids.

The nutmeg in the streusel adds a warming spice that aids digestion, making this dessert surprisingly beneficial for your gut.

Healthy Fat Balance

The recipe uses 1.5 cups unsalted butter, but the fat is balanced by the fiber-rich apples and whole grains. Butter provides 50% of your daily saturated fat needs per serving, but the portion size (one slice) keeps it moderate.

For a lighter option, I sometimes replace ¼ cup of the butter with applesauce—it reduces calories by about 100 per serving while keeping the moist texture.

Blood Sugar Benefits

The combination of low-glycemic apples and whole grain oats creates a dessert that won't spike blood sugar like refined sugar treats. The cinnamon in both the filling and streusel has been shown to improve insulin sensitivity.

For diabetics, I recommend serving with ½ cup Greek yogurt instead of ice cream to further stabilize blood sugar levels.

Antioxidant Boost

Granny Smith apples contain quercetin, a powerful antioxidant that fights inflammation. The brown sugar adds natural molasses flavor while providing trace minerals like calcium and potassium. Even the vanilla extract contributes antioxidants, making this dessert a surprisingly nutritious treat when enjoyed in moderation.

Portion Control Tip

One slice of this cake contains about 250 calories, with 12g of sugar (mostly natural from apples and brown sugar). To make it even lighter, I often serve it with 1 scoop protein powder mixed into Greek yogurt—this adds protein without overpowering the apple flavor.

The key is portion awareness: one slice is plenty to satisfy cravings while keeping the health benefits intact. 💪
