German Applesauce Cake (Apfelmuskuchen)
This authentic German Applesauce Cake (Apfelmuskuchen) combines a buttery cake base, a spiced applesauce filling, and a crunchy streusel topping in every irresistible bite. Passed down through generations and enjoyed during traditional Kaffee und Kuchen, this recipe transforms simple pantry staples into something truly special — no peeling or slicing fresh apples required. The applesauce layer keeps the cake incredibly moist for days, while the butter-rich streusel bakes into crunchy, cookie-like clusters that set authentic German baking apart.

Ingredients
For the Cake Base
- 2 cups all-purpose flour - 250g
- 2/3 cup granulated sugar - 135g
- 1/2 cup unsalted butter - 115g, softened to room temperature
- 1 large egg
- 1 tsp vanilla extract
- 1 1/2 tsp baking powder
- 1/4 tsp salt
For the Applesauce Filling
- 2 cups unsweetened applesauce - 480g; store-bought or homemade
- 1 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 2 tbsp cornstarch - increase to 3 tbsp if applesauce is thin or homemade
- 1 tbsp lemon juice - freshly squeezed preferred
For the Streusel Topping
- 1 1/2 cups all-purpose flour - 190g
- 2/3 cup granulated sugar - 135g
- 1/2 cup unsalted butter - 115g, cold and cut into small pieces
- 1 tsp ground cinnamon
- 1/4 cup sliced almonds - 30g, optional
Instructions
- Preheat oven to 350°F (180°C) with the rack in the center position. Grease a 9-inch springform pan with butter, line the bottom with parchment, then lightly dust the sides with flour and set aside.
- In a large bowl, whisk together 2 cups flour, baking powder, and salt until evenly combined.
- In a separate large bowl, beat softened butter and 2/3 cup sugar with an electric mixer on medium-high for 3–4 minutes until light, pale, and fluffy. Add the egg and vanilla extract and beat for 1 more minute.
- Add the flour mixture to the wet ingredients and mix on low speed just until no dry pockets remain — do not overmix. The dough will be thick and slightly sticky.
- Press two-thirds of the dough evenly across the bottom of the prepared pan and about 1 inch up the sides to form a shallow border. Refrigerate while you prepare the filling.
- Whisk together applesauce, cornstarch, cinnamon, and nutmeg in a medium saucepan until smooth, then cook over medium heat, stirring constantly, for 3–4 minutes until thickened. Remove from heat, stir in lemon juice, and let cool 5–10 minutes.
- Combine 1 1/2 cups flour, 2/3 cup sugar, and 1 tsp cinnamon in a bowl, then cut in the cold butter pieces using a pastry cutter or fingers until coarse crumbs with some pea-sized chunks form. Stir in almonds if using, squeeze into clumps, and refrigerate until needed.
- Remove the pan from the refrigerator and spread the cooled applesauce filling evenly over the dough base. Scatter any remaining cake dough over the filling, then crumble the streusel loosely over the entire surface without pressing it down.
- Place the pan on a baking sheet and bake for 45–55 minutes until the streusel is golden brown and a toothpick inserted into the cake portion comes out clean. Tent loosely with foil if the streusel browns too quickly after 30 minutes.
- Cool in the pan on a wire rack for at least 20 minutes before releasing the springform ring. Allow to cool completely (1–2 hours) before slicing for clean cuts, then serve at room temperature or slightly warm.
Notes
- Room temperature vs. cold butter: Use softened butter for the cake base (better creaming) and cold butter for the streusel (better crumble texture).
- Don't skip the cornstarch: Thickening the applesauce is essential to prevent a soggy base and ensure the filling sets properly when cooled.
- Better streusel clusters: Squeeze handfuls of streusel together before sprinkling to create a mix of chunky clusters and fine crumbs — this is key to authentic German streusel.
- Cool completely before slicing: Cutting too early results in runny filling; the applesauce layer needs 1–2 hours to fully set.
- Homemade applesauce: Works beautifully — just make sure it's fully cooled and increase cornstarch to 3 tbsp if it's on the thinner side.
- No springform pan? Use a greased and parchment-lined 9-inch round or 9×9-inch square cake pan and serve directly from the pan.
- Storage: Keep covered at room temperature for up to 3 days, or refrigerate for up to 5–6 days. Freeze individual slices (wrapped tightly) for up to 3 months.
- Reviving the streusel: If the topping softens during storage, place slices under the broiler for 1–2 minutes to crisp it back up.
- Make-ahead tip: The cake actually tastes better the next day once the flavors meld — ideal for preparing ahead of a gathering.
- Flavor variations: Try adding lemon zest to the base, swapping nutmeg for cardamom, or mixing golden raisins or mini chocolate chips into the filling for a fun twist.
