Preheat oven to 350 degrees F. Using parchment paper-lined a 7-inch cake pa ( a 6-inch cake pan or 8-inch cast-iron skillet will also work).
Add all ingredients to a mixing bowl, and using an electric mixer, mix for several minutes in well mixed.
You can also mix in a bowl with a wooden spoon or spatula if desired. If you go this route, you should probably whisk the almond flour to get out all the lumps and then add the remaining ingredients.
Pour batter into prepared cast iron skillet and smooth batter.
Bake for 35-40 minutes until a toothpick comes out clean. Baking time will depend on the size cake pan you use and your oven.
Cool completely before icing/frosting.
