Banana, Apple, and Walnut Cake. Ingredients: 3 eggs, 1 1/2 cups oatmeal, 1/2 cup coconut oil, 1 cup sugar, 3 ripe bananas, 3 red apples, 1/2 cup raisins, 1/2 cup walnuts, 1 tablespoon baking powder, 1 tablespoon ground cinnamon. Directions: Preheat oven to 180°C. Dice the bananas and apples into small cubes and place them in a bowl. Add the oatmeal, sugar, cinnamon, chopped walnuts, and baking powder. In a separate bowl, beat the eggs well with the coconut oil. Add the dry ingredients to the wet mixture and mix with a spatula until smooth. Grease a springform pan and dust with flour. Bake for about 45 minutes. Do the toothpick test: if it comes out clean, the cake is ready.
