01 - Preheat the oven to 350°F. Grease an 8-inch round cake pan and line the bottom with parchment paper.
02 - In a medium bowl, whisk together the flour, ground almonds, baking powder, and salt. Set aside.
03 - In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
04 - Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
05 - Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined, being careful not to overmix.
06 - Gently fold in the fresh raspberries by hand, taking care not to crush them.
07 - Pour the batter into the prepared pan and smooth the top with a spatula. Sprinkle the sliced almonds evenly over the surface.
08 - Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
09 - Let the cake cool in the pan for 10 minutes, then carefully transfer to a wire rack to cool completely.
10 - Dust with powdered sugar if desired and garnish with extra fresh raspberries before serving.
