Instructions

  1. 1

    Preheat oven to 350F and grease a 9-inch pan.

  2. 2

    Combine almond meal, buckwheat flour, salt, cinnamon, orange zest, and baking powder in a bowl.

  3. 3

    Beat butter with sugar until fluffy. Beat in egg yolks one at a time.

  4. 4

    Alternate adding the dry mixture and milk to the butter mixture, stirring until combined.

  5. 5

    Whip egg whites with remaining sugar until stiff peaks form.

  6. 6

    Stir one quarter of the egg whites into the batter to lighten, then gently fold in the remaining whites.

  7. 7

    Pour batter into greased pan and smooth the top.

  8. 8

    Bake for 50-60 minutes until a knife inserted in the center comes out clean. Cover loosely with foil if browning too quickly.

  9. 9

    Cool in pan for 10 minutes, then turn out and cool completely.

Tips

Tip 1

Separate eggs when cold, then bring to room temperature before beating for better volume and integration.
