Moist cake, spiced apples, and crispy streusel—just 14 ingredients for bakery-style donut cake.

The apples are the heart of this cake, so don't skimp on quality. Red Delicious or Honeycrisp work best—they hold their shape and stay tender. I always buy organic when possible, but regular apples work too if you peel them well. For the best flavor, peel and dice them right before mixing—they oxidize fast. If you're short on time, Trader Joe's pre-sliced apples (the organic ones) save steps. Just make sure they're not too watery, or your cake will get soggy. The cinnamon? Penzeys brand has the best ground cinnamon, but any good quality spice will do—just don't use that dusty stuff from the back of your pantry.

No Red Delicious apples? Granny Smith or Fuji work just as well—they're tart enough to balance the sweetness. Running low on oats? Quick oats blended into flour work in a pinch, but old-fashioned give that perfect crunch. The butter needs to be cold for that perfect streusel texture—take it out of the fridge 15 minutes before mixing. For a vegan version, swap the butter for coconut oil and use flax eggs (1 tbsp ground flax + 3 tbsp water = 1 egg). The vanilla extract matters here—alcohol-free versions have more concentrated flavor, but regular works too. If you're feeling fancy, add a pinch of cardamom to the cake batter for extra depth.

This cake keeps beautifully—3 days at room temperature wrapped in foil, or 5 days in the fridge covered tightly. For longer storage, freeze slices wrapped individually for up to 3 months. The streusel gets crispier as it sits, so it actually tastes better the next day. I like to reheat slices in the oven at 350°F for 5 minutes to bring back that fresh-from-the-oven crunch. Leftovers? Perfect for breakfast toast—just slice and warm!

Step-by-step instructions for apple cinnamon donut cake

Here's how to create layers of spiced apple swirls and crunchy oat topping that'll make this cake irresistible.

In a medium bowl, combine the 0.5 cup light brown sugar, 2 tbsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp salt, and 0.5 cup old-fashioned oats. Use your fingers to work the mixture until it becomes crumbly and evenly coated. Here's the thing—those oats need to be fully integrated with the spices so every bite gets that warm cinnamon crunch.

Set this streusel aside while you prepare the cake batter. I like to keep it in a separate bowl so it doesn't get mixed in accidentally. The texture should resemble wet sand—if it's too dry, add a teaspoon of milk to help it bind together.

In a large mixing bowl, beat the 1 cup unsalted butter (cold, cubed) with the 1.5 cups granulated sugar and 0.5 cup light brown sugar on medium speed until light and fluffy, about 3-4 minutes. You're looking for that ribbed texture that nearly doubles in volume—this incorporates air that'll make your cake tender.

I press down on the butter occasionally to make sure it's fully incorporated. If the mixture looks too thick, that's okay—it'll come together when we add the wet ingredients. The reason we use cold butter is to prevent the cake from becoming too dense.

Add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 1 tsp vanilla extract, 0.5 cup whole milk, and the 2 medium red delicious apples (finely diced). I like to press the apples through a fine-mesh strainer first to remove any excess moisture—this keeps the cake from getting too wet.

In a separate bowl, whisk together the 2.5 cups all-purpose flour (sifted), 2 tsp baking powder, and the remaining 0.5 tsp ground nutmeg. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Don't overmix—you should still see some flour streaks. The batter will be thick and slightly sticky, which is perfect for this dense cake texture.

Preheat your oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper. Pour half of the batter into the prepared pan, then sprinkle about half of the streusel mixture evenly over the top. Add the remaining batter, then top with the rest of the streusel, pressing down gently to help it stick.

Bake for 45-50 minutes until a toothpick inserted in the center comes out clean. The top should be golden brown with a beautiful caramelized crust from the streusel. If you notice the edges browning too quickly, tent the cake with aluminum foil after 30 minutes to prevent over-browning.

Let the cake cool in the pan for 15 minutes, then transfer it to a wire rack to cool completely. This resting period is crucial—it allows the cake to set properly and prevents it from falling apart when you serve slices.

Once completely cooled, dust the top generously with the 0.25 cup powdered sugar using a fine-mesh sieve. The sugar will catch on the warm spice notes and create that perfect balance of sweetness and warmth. Slice into wedges and serve warm with a scoop of vanilla ice cream for the ultimate dessert experience.

Storing and reheating this dish

Room Temperature Storage

This cake stays fresh for 3 days at room temperature when wrapped tightly in plastic wrap or foil. The secret is letting it cool completely first—1 hour on a wire rack prevents condensation that makes the streusel soggy. I like to store it in an airtight container with a paper towel underneath to absorb any moisture. The flavors actually deepen overnight, making it perfect for breakfast the next morning. 💛

Fridge Preservation

For longer storage, refrigerate for up to 5 days in an airtight container. The cold temperature helps maintain that perfect streusel crunch, though it may soften slightly. I always reheat slices before serving—wrap them in foil and warm at 350°F for 5 minutes. This brings back that fresh-from-the-oven texture while keeping the cake moist. The apples stay tender when properly stored this way.

Freezer-Friendly Slices

Individual slices freeze beautifully for up to 3 months. Wrap each slice tightly in plastic wrap, then place them in a freezer bag with all air removed. When ready to enjoy, thaw at room temperature for 1 hour or warm directly from frozen in the oven at 300°F for 8-10 minutes. The texture remains surprisingly good after freezing—just slightly more tender than fresh.

Reheating Secrets

For the best results, always reheat slices wrapped in foil. I use the oven method because it prevents the streusel from becoming gummy. A quick 3-5 minutes at 350°F restores that perfect balance of crispy top and soft cake. Microwave reheating works in a pinch (30 seconds on medium power), but the texture suffers slightly. The key is speed—don't overheat or the apples will turn mushy.

Make-Ahead Tips

This cake bakes perfectly ahead of time—prepare it up to 2 days in advance and store covered at room temperature. The flavors meld beautifully, making it ideal for holiday gatherings. For parties, I like to assemble the cake (without baking) the night before, then bake it fresh in the morning. This ensures maximum freshness and that signature crackly streusel. The apples stay vibrant when stored properly this way. ✨
