Preheat oven to 350 degrees.

Grease a 9-inch round cake pan.

In a medium bowl, whisk together the butter and eggs. Add the flour, sugar, and almond extract. Stir with the whisk until combined. Pour the mixture into the prepared cake pan. Sprinkle the sliced almonds over the top.

Bake in the oven for 25 to 30 minutes or until a toothpick inserted in the middle comes out clean. Allow the cake to slightly cool and then remove cake from pan onto a serving plate. Sprinkle powdered sugar over the top. Slice and enjoy!
