Desserts
This apple buttermilk coffee cake recipe delivers all the comfort of a bakery-style dessert with tender crumb, spiced apple filling, and a buttery streusel topping—all baked in one bowl.
The secret lies in balancing sweet and tart apple pieces with a moist buttermilk batter that stays perfectly tender even after baking. I've tested this recipe countless times, and it consistently yields a cake with a golden crust, soft interior, and just the right amount of cinnamon warmth.
The beauty of this recipe is its simplicity—no fancy techniques required. You'll start with a basic cake batter, fold in diced apples and a spiced filling, then top it with a quick streusel made from flour, sugar, and butter.
The buttermilk keeps the cake tender while the streusel adds texture and caramelized flavor. Baking time is just 50-55 minutes at 350°F, making it perfect for a weekend breakfast or dessert that feels like a hug.
What makes this coffee cake truly special is how the flavors develop as it bakes. The apples soften just enough to release their juices, which are then absorbed by the cake while still maintaining their texture.
The streusel topping becomes golden and crunchy, creating a perfect contrast to the tender crumb below. Each slice is loaded with warm apple pieces and that signature buttery, cinnamon-spiced flavor that makes it irresistible.
Serve warm with a dusting of powdered sugar or a scoop of vanilla ice cream for the ultimate comfort food experience. This recipe is designed to be foolproof, so even if you're not an experienced baker, you'll achieve restaurant-quality results. Let's get started on baking this classic apple coffee cake!
Ingredients for apple buttermilk coffee cake
Tender crumb meets buttery streusel in this one-bowl apple coffee cake.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for best texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light brown preferred |
| Buttermilk 🥛 | 1 ½ cups | Full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Melted Butter 🧈 | 1 cup | Unsalted, cooled slightly |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Medium Apples 🍎 | 4 whole | Sweet-tart variety (e.g., Honeycrisp) |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for streusel |
| All-Purpose Flour 🌾 | ½ cup | For streusel topping |
| Packed Brown Sugar 🍚 | ¼ cup | For streusel topping |
| Ground Cinnamon 🌿 | 1 tsp | For streusel topping |
The apples are the star—Honeycrisp or Fuji give the best balance of sweet and tart. Trader Joe's or Whole Foods usually have pre-washed, pre-cut apples in the produce section, saving you time. If using whole apples, peel and dice them into 1/2-inch pieces—don't skip the peel, it adds flavor! Toss them with a teaspoon of lemon juice to keep them from browning while you prep. For extra caramelization, I like to sprinkle the diced apples with 1/4 cup sugar before folding them into the batter.
No buttermilk? Mix 1.5 tbsp lemon juice or vinegar with 1.5 cups milk and let sit for 5 minutes. The streusel topping can be made ahead—just store the dry ingredients (flour, sugar, cinnamon) in a jar and mix with cold butter when ready to bake. Swapping apples? Pears or peaches work well, but increase the sugar by 1-2 tablespoons if using tart varieties. For a deeper spice flavor, add 1/4 tsp cardamom to the streusel—it pairs beautifully with apple.
Prep the apples last—toss them with lemon juice and set aside while mixing the batter. The batter can be made 1 day ahead and stored in the fridge, but let it sit at room temperature for 30 minutes before baking. The streusel should be mixed right before folding it into the batter. This cake keeps well for 3 days at room temperature or 5 days in the fridge. For best texture, reheat slices in the oven at 350°F for 5-10 minutes—they taste like they just came out of the oven!

Step-by-step instructions for apple buttermilk coffee cake
This one-bowl wonder delivers tender crumb, spiced apples, and a buttery streusel topping—all in one easy mix.
Prepare the Apples and Preheat the Oven
Peel, core, and slice the 4 whole medium apples into ¼-inch thick slices. Toss them with 1 tablespoon of the granulated sugar and ½ teaspoon of the ground cinnamon to keep them from browning. Set aside.
Preheat your oven to 350°F and grease an 8x8-inch baking dish or 9-inch round cake pan with 1 tablespoon melted butter, rubbing it evenly over the bottom and sides. This prevents sticking and ensures easy removal later.
Mix the Batter in One Bowl
In a large mixing bowl, combine the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 0.5 cup packed brown sugar, 2 teaspoons baking powder, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Whisk until evenly distributed—no need to overmix, just break up any flour clumps.
Add the 1.5 cups buttermilk, 2 whole large eggs, and 1 cup melted butter to the dry ingredients. Stir with a spatula or wooden spoon until just combined—you should see a thick, slightly lumpy batter. The buttermilk adds moisture and tang, while the melted butter keeps the cake tender.
Fold in Apples and Bake
Gently fold the prepared apple slices into the batter using a spatula, making sure they’re evenly distributed. Pour the mixture into your prepared baking dish and smooth the top with the back of a spoon. The batter will be thick but should spread evenly in the pan.
Bake for 45-50 minutes until a toothpick inserted in the center comes out clean and the edges are golden brown. If the top browns too quickly, tent loosely with foil after 30 minutes to prevent over-browning while the center finishes baking.
Make the Streusel Topping
While the cake bakes, prepare the streusel topping in a small bowl. Cut the 0.5 cup unsalted butter into small cubes and rub them between your fingers until crumbly. Mix with the 0.5 cup all-purpose flour, 0.25 cup packed brown sugar, and 1 teaspoon ground cinnamon until it resembles coarse sand. The texture should be slightly gritty but hold together when pressed.
Top and Finish Baking
Remove the cake from the oven and sprinkle the streusel topping evenly over the surface. Return it to the oven for 10-12 minutes until the streusel is golden brown and bubbly. The residual heat will help it crisp up beautifully.
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. Serve warm with a pat of butter or a drizzle of maple syrup for that extra cozy touch. This cake keeps well at room temperature for 2-3 days or can be frozen for up to 3 months—perfect for meal prep or holiday baking!
Pro Tips For Making Apple Buttermilk Coffee Cake
- Mix Dry First: Dump the flour, brown sugar, and spices into your bowl before cracking in the eggs and buttermilk. I learned this the hard way—skipping it leads to lumps that ruin the tender crumb, and no one wants a coffee cake with texture issues. Stir gently just until combined (yes, even if you’re impatient like me).
- Chill the Dough: Pop the batter in the fridge for 15–30 minutes before baking. This isn’t about being fancy—it’s about preventing a dome-shaped cake that collapses mid-bake. The apples will stay juicy, and the crumb stays light, not dense.
- Don’t Overmix Apples: Toss the apples with just a pinch of flour and cinnamon—no need to coat them heavily. Overmixing releases too much juice, turning your cake into a soggy mess. A quick stir to distribute is all it takes.
- Test for Doneness Early: Start checking at 30 minutes (ovens vary, and this isn’t a cake that waits). A toothpick should come out clean, but the edges should still be slightly springy—not rock-hard. Pull it too soon, and the center stays doughy; leave it too long, and the top turns brick-red.

Frequently asked questions
Can I use regular milk instead of buttermilk?
Yes, but you'll need to substitute it properly! Mix 1.5 tablespoons lemon juice or vinegar with 1.5 cups milk and let it sit for 5 minutes until slightly thickened. This mimics buttermilk's tangy acidity, which keeps the cake tender. Just don't skip this step—the cake won't rise as well without it!
How do I prevent my cake from being too dry?
Overmixing or overbaking are the usual culprits! Stir the batter just until combined—lumpy is fine. Bake until a toothpick comes out clean (45-50 minutes at 350°F), but don't exceed 55 minutes. For extra moisture, add 1 tablespoon apple juice to the batter or brush the top with melted butter during baking. The buttermilk already helps, but these tweaks ensure a perfect crumb.
Can I make this cake in a different pan?
Use an 8x8-inch square pan (recommended) or a 9-inch round cake pan. If using a round pan, reduce baking time by 5 minutes—they cook faster. Grease the pan well and consider lining it with parchment paper for easy removal. The batter should fill the pan about 2/3 full for best results.
What's the best way to store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days—it actually tastes better the next day! For longer storage, freeze slices wrapped in plastic for up to 3 months. To reheat, warm in a 350°F oven for 5-7 minutes until the streusel is crisp again. The apples stay juicy and flavorful!
Can I add nuts or chocolate chips?
Yes, but go light! Fold in ½ cup chopped walnuts or pecans with the apples, or sprinkle ¼ cup mini chocolate chips on top before adding the streusel. For a balanced texture, stick to 1 type of add-in—too many extras can make the cake dense. Toast the nuts first for extra flavor!
