To make your own Irresistible Raspberry Almond Crumb Cake, follow these simple steps:

1. Preheat the Oven: Set your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easier removal.
2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, almond flour, granulated sugar, baking powder, and salt until combined.
3. Whisk Wet Ingredients: In another bowl, mix the melted butter, eggs, milk, and almond extract until well blended.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients, stirring gently until just combined. Avoid overmixing.
5. Fold in Raspberries: Gently fold in the fresh raspberries, being careful not to break them apart too much.
6. Prepare Crumb Topping: In a small bowl, combine the sliced almonds, brown sugar, ground cinnamon, and remaining ½ cup of flour. Mix until crumbly.
7. Pour Batter Into Pan: Spoon the batter into the prepared baking pan, spreading it evenly.
8. Add Crumb Topping: Sprinkle the almond crumb topping generously over the batter.
9. Bake: Place in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Once baked, remove from the oven and let it cool in the pan for 15-20 minutes. Transfer to a wire rack to cool completely before slicing.
