Creating the delightful German Blueberry Cake is straightforward when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease and flour three 9-inch round cake pans.
2. Combine Dry Ingredients: In a bowl, mix together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy.
4. Add Eggs: Beat in the eggs one at a time, incorporating each well before adding the next.
5. Mix in Vanilla and Lemon Zest: Stir in the vanilla extract and lemon zest until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture alternately with the milk, starting and ending with the dry ingredients. Mix until smooth.
7. Fold in Blueberries: Gently fold in the fresh blueberries, taking care not to break them.
8. Divide Batter: Evenly divide the batter among the prepared cake pans.
9. Bake: Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
10. Cool: Remove the cakes from the oven and allow them to cool in the pans for about 20-30 minutes. Then, transfer them to wire racks to cool completely.
11. Layer the Cake: Once cooled, place one layer on a plate, and spread a layer of whipped cream on top. Add another cake layer, repeat the process, and finish with the final layer.
12. Dust with Powdered Sugar: For an elegant finish, dust the top with powdered sugar just before serving.
