Flourless Walnut Cake with Apples and Cinnamon (Gluten Free)

Flourless Walnut Cake with Apples and Cinnamon (Gluten Free)

Fall is here and this flourless walnut cake with apples and cinnamon is so perfect for this time of year. It combines my favorite fall flavors in one. When I was a child, my mom used to prepare a cake with apples walnuts and cinnamon, but it was with flour and white sugar. When I was creating this recipe, I thought about that cake specifically. I wanted the same taste but healthier. While in my mom’s recipe there was a handful of walnuts, in mine they are the main ingredient. I ground them finely and used them instead of flour. I also replaced the refined sugar with coconut, which contains more nutrients, and it doesn’t spike your blood glucose levels. The cake turned out great. I honestly can’t stop eating it. I hope you make it too and share your opinion.

Helpful tips

This tip is not related to this recipe, but I think that it is very helpful. When you buy fresh nuts that you don’t plan using right away store them in the refrigerator. They are going to last much longer. I store all my fresh nuts and nut flours in the refrigerator.

You can replace walnuts with pecans. You can also use regular sugar if you prefer it. I like coconut sugar because of its caramel flavor and the health benefits it provides.

Squeeze as much liquid as you can out of the grated apples. This step will help you achieve a better cake texture.

Use a food processor to grind the walnuts finely. Then transfer them into a bowl and use the same food processor to grate the apples. This will save you so much time and effort.

There is no baking soda or baking powder in this recipe. The whipped egg whites have so much air in them that there is no need to add a leavening agent. You just have to carefully fold them in the batter.

Store leftovers in the fridge. If you leave the cake on the countertop int will become moldy in two-three days.
