Step 1: Preheat the oven to 350°F (175°C).
Step 2: Grease your 9-inch round cake pan with butter or cooking spray.
Step 3: In a mixing bowl, combine melted butter and sugar, whisking until blended. Add eggs one at a time, mixing well. Stir in almond extract.
Step 4: In a separate bowl, mix flour and sliced almonds. Gradually add to wet ingredients, stirring until just combined.
Step 5: Pour batter into the prepared cake pan and bake for 25-30 minutes, until a toothpick comes out clean.
Step 6: Cool in the pan for 10 minutes, transfer to a cooling rack, and dust with powdered sugar.
