Chocolate Walnut Layer Cake

Directions

1. Preheat the oven to 335F and prepare a 6-inch cake pan (do NOT grease or line the pan)

2. Mix the oil and cake flour until combined. Sift in the cocoa powder and mix in the yolks and milk

3. In a separate bowl, whip the egg whites. Add the sugar in 3 parts and whip until stiff peaks

4. Add 1/3 of the meringue to the yolk mixture and mix until fully combined. Pour the yolk mixture into the remaining meringue and gently fold until combined

5. Pour the batter into the cake pan. Lightly tap the pan to pop big air bubbles before covering it with a foil tent

6. Bake for 25 minutes. Lower the temperature to 315F, remove the foil tent, and bake for 25 more minutes. Invert the pan onto a cooling rack to cool completely. Slice the cake into three layers

7. Beat the heavy cream and sugar to soft peaks. Add the walnut butter and beat until medium stiff peaks

8. To assemble, layer a slice of cake with walnut cream and walnut pieces. Repeat with the remaining layers. Frost the cake with walnut cream and top with more walnuts. Chill for 3 hours before serving
