Ingredients for apple cinnamon donut cake

Simple ingredients transform into a bakery-worthy apple cinnamon donut cake with crispy crowns.

The apples are non-negotiable here—Honeycrisp or Fuji stay firm when diced and add perfect sweet-tart flavor. Grab them at Whole Foods if you want the best, but any firm, crisp variety works. If you're short on time, pre-peeled apples from the salad bar (yes, really) save 10 minutes. For the flour, King Arthur or Gold Medal brands give the best texture. If you're baking in a humid climate, add an extra 1/4 tsp baking powder to prevent a dense cake. The cinnamon? Penzeys or McCormick ground cinnamon has the warmest flavor—avoid the pre-mixed spice packets.

No vanilla extract? Vanilla bean paste or even vanilla sugar works in a pinch. Short on butter? Coconut oil or shortening keeps the cake tender, but butter gives that rich flavor. For the frying oil, vegetable or canola oil is perfect—just make sure it's 350°F. If you can't find cinnamon sugar mix, combine 1/4 cup sugar with 1 tbsp cinnamon. The apples can be raw or lightly sautéed with lemon juice to prevent browning—I do both for extra flavor. For a gluten-free version, swap the flour for a 1:1 gluten-free baking blend.

Store the cake layers in an airtight container between parchment paper for up to 3 days. The frosting can be made 1 day ahead and refrigerated. For the donut crowns, fry them fresh and serve immediately—they lose crispness fast. If you need to prep ahead, bake the cake and freeze it (unfrosted) for up to 1 month. Thaw at room temperature before frying the crowns. The frosting keeps for 5 days in the fridge, so make extra for sandwiches or cupcakes.

Step-by-step instructions for apple cinnamon donut cake

Here's how to create a moist cake with spiced apple filling and crispy fried crowns.

Preheat your oven to 350°F and grease a 12-cup donut pan (or line with donut liners). In a large mixing bowl, combine the 2.5 cups all-purpose flour, 2 tsp baking powder, 2 tsp ground cinnamon, and 0.5 tsp salt. Whisk until evenly distributed—this ensures your cake rises properly.

In a separate bowl, cream together the 1 cup unsalted butter (at room temperature), 1.5 cups granulated sugar, and 0.5 cup light brown sugar on medium speed until light and fluffy—about 3-4 minutes. This step incorporates air, which gives your cake that classic tender texture. Scrape down the sides of the bowl to ensure even mixing.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 tbsp vanilla extract and 0.75 cup whole milk until smooth. Gradually add the dry ingredients to the wet, mixing on low speed just until combined—overmixing develops gluten and makes the cake tough. Fold in the 2 peeled, finely diced apples using a spatula to distribute them evenly throughout the batter.

Carefully fill the greased donut pan cavities 2/3 full with batter, using a piping bag or spoon. Bake for 12-15 minutes or until the tops spring back when gently touched and a toothpick inserted comes out clean. Rotate the pan halfway through baking for even donuts—this prevents uneven browning.

Here's the thing—don't open the oven door early. The heat should circulate freely, and peeking too soon can cause the donuts to sink. When they're done, remove them immediately and let them cool in the pan for 5 minutes before transferring to a wire rack. This brief resting period helps them set properly for the next step.

While the donuts cool, heat 0.5 cup vegetable oil in a deep skillet over medium heat until it reaches 350°F—use a thermometer for accuracy. Cut each donut in half horizontally, creating two rounds. Gently press a small hole in the center of each round to create a crown shape.

Carefully place the donut rounds into the hot oil, cut-side down. Fry for 30-45 seconds per side until golden brown. You'll see bubbles form and the edges crisp up—that's your signal they're ready. Remove with a slotted spoon and drain on paper towels. If the oil isn't hot enough, the crowns will absorb oil instead of crisping.

Once the crowns are cool enough to handle, dip the edges into the 0.5 cup cinnamon sugar mix, pressing gently to adhere. This creates that signature crunchy exterior that contrasts perfectly with the tender cake. Place the donut halves back together, with the fried crowns on top, and transfer to a serving plate.

Pipe or spread the 2 cups buttercream frosting over the top and sides of each donut. I like to use a piping bag with a star tip for an elegant finish. The frosting should be thick enough to hold its shape but smooth enough to spread easily. Serve immediately while the crowns are still crisp for that perfect texture contrast in every bite.

Dietary considerations for apple cinnamon donut cake

Gluten-Free Adaptation

For a gluten-free version, swap the all-purpose flour for a 1:1 gluten-free baking blend like King Arthur Measure for Measure or Bob's Red Mill. These blends contain xanthan gum, which mimics gluten's structure for proper rise and texture. I've tested this with great success—just make sure your blend includes 2 tsp xanthan gum per cup of flour. The cake will still be tender but slightly denser than the original. 🌾

Dairy-Free Options

Replace the butter with Earth Balance dairy-free butter or coconut oil (solid at room temperature) for a rich flavor. Use unsweetened almond milk or oat milk instead of whole milk, but add 1 extra tbsp of milk to compensate for reduced fat. The texture remains moist, though slightly less rich. For the frosting, use a dairy-free buttercream made with Miyoko's creamery butter or vegan butter.

Lower Sugar Version

Reduce the granulated sugar to 1 cup and replace the remaining 0.5 cup with unsweetened applesauce or mashed banana. This cuts calories while keeping moisture. For the frosting, use a lightened buttercream with powdered erythritol or monk fruit sweetener instead of half the sugar. The cake stays tender, and the apples' natural sweetness shines through. 🍎

Nut-Free Considerations

Skip the cinnamon sugar mix if it contains nuts (some brands add chopped nuts). Instead, mix 0.5 cup sugar with 2 tbsp ground cinnamon yourself. For the frosting, use a vanilla buttercream without nut extracts. Always check labels—Penzeys cinnamon is nut-free, but McCormick's some blends contain traces. When in doubt, buy spices in bulk or from specialty stores.

Vegan Adaptation

Use flax eggs (2 tbsp ground flaxseed + 6 tbsp water per egg) and vegan butter like Miyoko's. Replace milk with unsweetened soy milk (high protein helps bind). For the frosting, make a vegan buttercream with coconut cream whipped to stiff peaks. The texture stays moist, though slightly denser. Fry the crowns in vegetable oil as usual—they'll still crisp beautifully. ✨
