Notes

*Make sure to sift the almond and coconut flour before measuring the dry ingredients.  Careful measuring will help ensure success of cakes.

*You can use a 9x5 inch loaf pan for this recipe, although it may take 10 minutes or so longer to bake.  Test with toothpick at 45 minutes.

*A 8 inch square pan can be used as well.  It will bake at about 35 minutes.  Test, bake an additional 5 minutes or so as needed.

*If you don't have brown sugar substitute, you can use all white granulated sugar substitute.  The flavor of the cake will be slightly different.

*Don't leave out the xanthan gum or glucomannan powder.  They improve the texture of grain free cakes and help improve the rise of the cake.
