This gluten-free apple cinnamon cake is a perfect dessert for people with gluten intolerance or celiac disease. It's made with almond flour, coconut sugar, and applesauce instead of wheat flour. The cake is moist, tender, and packed with protein and healthy fats. To make this cake, you'll need almond flour, baking powder, cinnamon, salt, coconut sugar, eggs, unsweetened applesauce, vanilla extract, and chopped apples. Mix the dry ingredients in one bowl and the wet ingredients in another. Combine the two mixtures and fold in the chopped apples. Pour the batter into a greased baking pan and bake for 35-40 minutes. Serve warm or at room temperature.
