Almond Ricotta Cake

Step 1
Preheat the oven to 325 degrees F (165 degrees C). Grease an 8-inch springform pan and line with parchment paper.

Step 2

Step 3
Fold in almond flour and ricotta cheese with a silicone spatula.

Step 4
Wash and dry the beaters and beat egg whites in a glass, metal, or ceramic bowl until foamy. Gradually add 1/3 cup sugar, continuing to beat until stiff peaks form. Fold stiff egg whites into the batter. Pour batter into the prepared pan. Sprinkle with sliced almonds.

Step 5
Bake on the center rake of the preheated oven until edges of the cake are lightly browned, about 50 minutes. Cake will still be a little wobbly in the middle.

Step 6
Remove from the oven and let the cake to cool completely in the pan before transferring to a cake platter, about 1 hour. Dust with confectioners' sugar before serving.
