Cassava Flour-Apple Cake

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Grease a 9-inch square, deep baking dish.

2 . Stage

Combine raisins and Marsala wine in a bowl; set aside to soak.

3 . Stage

Sift cassava flour twice into a large mixing bowl. Mix in superfine sugar, baking powder, cinnamon, and nutmeg. Add almond meal and buckwheat flour and sift all the dry ingredients together.

4 . Stage

Combine eggs, butter, milk, oil, and vanilla extract in a bowl. Beat on low for with a hand mixer for 1 minute until well combined. Beat on high until fluffy, for a full 2 minutes. (This is a crucial step to ensure a fluffy cake.) Mix in grated apple. Stir in raisins and wine until combined.

5 . Stage

Carefully fold egg mixture into flour mixture with a rubber scraper, folding with light, yet deep strokes from the bottom to the top, until batter is just combined and still a bit lumpy, with no visible pockets of flour, being careful not to overmix. Pour batter into the prepared baking dish.

6 . Stage

Arrange apple slices to completely cover the batter, making sure they do not overlap too much; you may not need all of the slices. Sprinkle with raw cane sugar and pine nuts.

7 . Stage

Bake in preheated oven until a toothpick inserted into the center comes out clean, about 30 minutes. Switch to the broiler function and cook until the top is slightly browned, about 2 minutes.

8 . Stage

Remove from the oven and allow to cool slightly before cutting and serving.
