Ingredients
For the cake:
- 120 g softened butter
- 250 g flour
- 1 1/2 tsp baking powder
- 200 g sugar
- 2 eggs
- 200 g sour cream
- a pinch of salt
For the apples:
- 3 apples
- 1 tsp lemon juice
- 50 g brown sugar
- 1 tbsp flour
- 1/2 tsp cinnamon
- a pinch of salt
- a pinch of nutmeg
For the Streusel:
- 50 g softened butter
- 60 g flour
- 50 g brown sugar
- 1/2 tsp cinnamon
- a pinch of salt
- 50 g roasted and chopped hazelnuts/almonds
Peel, core, and dice apples. Toss the apples with lemon juice. Add the dry ingredients. Stir and set aside.
In a large bowl, whisk together flour, baking soda, cinnamon, and salt. In another large bowl, beat together butter and sugar. Beat in the eggs, one at a time. Add the flour mixture, alternating with the sour cream. Pour cake into pan ( lightly buttered before). With a spatula, smooth out the top. Arrange the apple slices on the top of the batter.
To make the streusel topping, combine all the ingredients until it forms a crumbly mixture. Sprinkle streusel evenly over the apples.
Bake in preheated oven at 180 degrees C around 40 min or until cake is golden brown. Let cool in pan 15 minutes, then turn out onto rack and let cool.
