01 - Preheat the oven to 350°F. Grease an 8-inch round cake pan and line the bottom with parchment paper.
02 - Whisk together flour, ground almonds, baking powder, and salt in a medium bowl. Set aside.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, about 3-4 minutes.
04 - Beat in eggs one at a time, fully incorporating each before adding the next. Stir in vanilla extract.
05 - Gradually add dry ingredients to the wet mixture, alternating with milk. Mix until just combined, being careful not to overmix.
06 - Gently fold in fresh raspberries by hand using a spatula, taking care not to crush the fruit.
07 - Pour batter into the prepared pan and smooth the top evenly. Sprinkle sliced almonds over the surface.
08 - Bake for 35-40 minutes until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
09 - Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
10 - Dust the cooled cake generously with powdered sugar and garnish with extra fresh raspberries before slicing and serving.
