Preheat the oven to 350°F. Grease the 9" springform pan with baking cooking spray or butter. Recommend putting some parchment paper on the bottom of the pan & along the sides first.
Crumb
In a small bowl: combine flour, brown sugar, cinnamon, salt and mix. Add melted butter & mix until it begins to form coarse crumbs.
Cake
In a bowl: add the flour, baking powder, baking soda, and salt then mix. Highly recommend that you sift the dry ingredients before mixing them into the wet ingredients. This will form a smoother batter and the cake will be very soft & fluffy.
In a large separate bowl: combine the eggs and sugar then beat. Then add sour cream, vanilla extract, almond extract, melted butter and mix everything together until smooth. Add the dry ingredients and mix everything together.
Transfer the batter to the pan. Add fresh raspberries on top of the batter- if using frozen raspberries, do not thaw. Add 6 tbsp of sliced almonds. Then, add the crumb on top. Sprinkle the rest of the sliced almonds on top of the crumbs.
Bake for 35-40 minutes (40-45 minutes if using frozen raspberries) or until a toothpick placed in the center comes out clean. Remove from the oven and rest the cake in the pan for 15 minutes. Then transfer the cake to a baking rack.
Garnish with powdered sugar on top. Slice, serve & enjoy!
