Preheat the oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper.
In a medium bowl, mix together the almond flour, semolina flour, baking powder, and salt. Set aside.
In a large bowl, beat together the butter and 1 cup of granulated sugar until pale and fluffy. Beat in the eggs, milk and almond extract, then fold in the flour mixture just until combined.
Transfer the batter into the prepared cake pan, smoothing with a spatula to even out. Sprinkle the slivered almonds and remaining tablespoon granulated sugar over the top.
Bake in the preheated oven for 30 minutes, or until golden brown and firm in the center, and a cake tester comes out clean.
Let cool completely in the pan before slicing and serving.
