Applesauce Sour Cream Coffee Cake Recipe: Moist Apple-Infused Layers With Buttery Streusel Crown

This applesauce sour cream coffee cake delivers the perfect balance of tender crumb and buttery streusel—every bite is moist, flavorful, and irresistibly comforting.

The secret lies in blending applesauce and sour cream into the batter, creating a cake that stays soft for days while the streusel crown adds a satisfying crunch. I’ve perfected this recipe over years of baking, ensuring it’s foolproof for both beginners and seasoned bakers alike.

The applesauce keeps the cake incredibly moist without adding extra moisture, while the sour cream adds richness and a delicate tang. The streusel topping, made with flour, brown sugar, and cold butter, bakes into a golden, caramelized crown that contrasts beautifully with the soft layers beneath.

This recipe is ideal for breakfast, brunch, or dessert—it’s versatile enough to fit any occasion while delivering restaurant-quality results at home.

What sets this coffee cake apart is its texture: the tender, apple-infused layers hold up perfectly, even when sliced the next day. The streusel doesn’t turn greasy or overly sweet, thanks to a precise balance of ingredients.

Whether you’re serving it warm with a pat of butter or saving slices for later, this cake never disappoints. The aroma alone will have everyone gathering around the kitchen.

Ready in just one hour, this recipe is perfect for weekend baking projects or last-minute gatherings. The instructions are straightforward, and the ingredients are simple—no fancy techniques required. Once you try this version, you’ll never go back to store-bought coffee cake again. Let’s get started!

Ingredients for applesauce sour cream coffee cake

Nine simple ingredients create a coffee cake with perfect moist crumb and buttery streusel crown.

The quality of your butter and applesauce makes all the difference here. For the butter, Plugrá or Land O’Lakes unsalted work beautifully—avoid salted or European-style butter, which can alter the texture. The applesauce should be unsweetened and unseasoned; Mott’s or Libby’s are reliable choices, but store brands work too if they’re free of additives. If you’re feeling ambitious, homemade applesauce (cooked down with cinnamon and a touch of lemon juice) elevates the flavor even further. The sour cream should be full-fat—Kroger or Trader Joe’s brands are excellent options for this recipe.

No applesauce on hand? Unsweetened applesauce substitute like pumpkin puree or mashed ripe banana (adjust liquid ratios accordingly) works in a pinch, though texture may vary slightly. Running low on brown sugar? White sugar plus a pinch of molasses mimics the flavor profile. For the streusel, if you prefer a crunchier topping, add an extra 2 tbsp of flour to the mix. The baking powder is crucial—Aluminum-free brands like Rumford ensure a tender crumb rather than a metallic aftertaste. And while vanilla extract is traditional, a vanilla bean paste adds depth without extra effort.

This coffee cake keeps beautifully—3 days at room temperature wrapped in foil or 5 days refrigerated in an airtight container. For longer storage, slice and freeze portions for up to 3 months. To reheat, warm slices in a 350°F oven for 5-7 minutes or microwave for 15-20 seconds. The streusel topping stays crisp when stored properly, so avoid overbaking. If you’re prepping ahead, mix the dry streusel ingredients in advance and store in a sealed container—just add the cold butter when ready to bake.

Step-by-step instructions for applesauce sour cream coffee cake

Here's the method for achieving a perfectly moist, tender crumb with a buttery streusel crown.

In a large mixing bowl, combine the 2.5 cups all-purpose flour, 2 teaspoons baking powder, 1 teaspoon ground cinnamon, and ½ teaspoon salt. Whisk these dry ingredients together until evenly distributed—this ensures consistent leavening throughout the cake. In a separate bowl, beat the 1 cup unsalted butter and ½ cup packed brown sugar together until light and fluffy, about 3-4 minutes using an electric mixer.

Add the 1 cup granulated sugar and continue beating until the mixture becomes pale and airy. This creaming process incorporates air, which creates that signature tender texture. With the mixer running on low speed, add the 2 whole large eggs, one at a time, making sure each is fully incorporated before adding the next. Finally, stir in the 1 cup unsweetened applesauce and ½ cup sour cream until just combined—overmixing at this stage can develop gluten and make the cake dense.

Add the 1 tablespoon vanilla extract to the wet mixture and stir gently to combine. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the flour is incorporated. The batter should be smooth but slightly thick—this is perfect for creating that moist crumb. Avoid overmixing, as this can lead to a tough cake. Once fully combined, pour the batter into a greased and floured 9x13-inch baking pan, spreading it evenly to create a uniform layer.

Here's the thing—don't tap the pan to release air bubbles. Simply use a spatula to smooth the top, ensuring even baking. The batter should fill the pan to about ½ inch thickness, which is ideal for creating those tender layers without being too dense.

While the cake batter rests, prepare the streusel topping in a separate bowl. Cut the remaining ½ cup cold unsalted butter into small cubes and combine with the ½ cup all-purpose flour (for streusel), ¼ cup packed brown sugar (for streusel), ½ teaspoon ground cinnamon (for streusel), and ⅛ teaspoon pinch of salt (for streusel). Use your fingers or a pastry cutter to work the mixture until it resembles coarse crumbs with pea-sized butter pieces—this ensures a perfect balance of texture and flavor.

The streusel should be slightly crumbly but hold together when pressed. If it feels too dry, add a teaspoon of cold water to bind it. Sprinkle the streusel evenly over the cake batter, pressing down gently to ensure good contact. This step is crucial for creating that signature buttery crown that contrasts beautifully with the moist cake layers.

Preheat your oven to 350°F and bake the coffee cake for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the top should be evenly covered with a crisp streusel layer. I know it seems like a long time, but patience here is key—underbaking can leave the cake gummy, while overbaking dries it out.

When the cake is done, remove it from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This resting period allows the cake to set properly and prevents it from becoming soggy. Serve warm for the best texture, with a dusting of powdered sugar or a dollop of whipped cream if desired.

Storing and reheating this dish

Room Temperature Storage

This coffee cake stays fresh for 3 days at room temperature when wrapped tightly in plastic wrap or foil. I like to place it on a wire rack first to cool completely, then wrap it snugly to prevent moisture buildup.

Store it in a cool, dark place like a pantry—avoid the countertop if your kitchen gets warm. The streusel stays crisp, and the cake maintains its moist texture perfectly. 🌟

Refrigerator Preservation

For longer freshness, refrigerate the cake in an airtight container for up to 5 days. The cold slows down staling, but the texture may become slightly denser. To revive it, let slices sit at room temperature for 10-15 minutes before serving.

I recommend cutting the cake into portions before refrigerating so you can grab individual servings without thawing the whole pan.

Freezing for Later

Slice the cake and freeze individual portions in single layers on a baking sheet for 1 hour to prevent sticking. Then transfer to quart-sized freezer bags or airtight containers, removing as much air as possible.

This method preserves the cake for up to 3 months—the streusel remains crisp, and the cake stays moist when reheated properly. 🧊
