Making your Raspberry Almond Crumb Cake is an exciting journey. Follow these simple steps to create your delicious cake:

1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan.
2. In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, baking soda, and salt. Mix until well blended.
3. In a separate bowl, beat the softened butter until smooth. Add the eggs one at a time, mixing thoroughly after each addition.
4. Stir in the vanilla extract and sour cream until the mixture is creamy and combined.
5. Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Do not overmix.
6. Carefully fold in the fresh raspberries. Avoid breaking them as you mix.
7. In a small bowl, combine the sliced almonds, brown sugar, and cinnamon for the crumb topping.
8. Pour the batter into the prepared baking pan and spread it evenly.
9. Sprinkle the crumb mixture evenly on top of the batter.
10. Bake in the preheated oven for 40-45 minutes or until a toothpick inserted in the center comes out clean.
11. Once baked, remove the cake from the oven and allow it to cool in the pan for 15-20 minutes before transferring it to a wire rack to cool completely.
