"Gluten-free, grain-free, and sugar-free brownies. Once done, no one will ever know they contain avocados. I know it sounds crazy, but the avocados really do work! They make these brownies very creamy."
You can sub sugar for honey, but since honey is sweeter you may want to increase the sugar content, this may also affect the moistness of the final product.
You can substitute butter for coconut oil or vice versa, but do not attempt to substitute any other flours for the coconut flour. This recipe is meant to replace wheat-based flours and coconut flour is well known to soak up a lot of moisture. It will change the consistency if this is changed.
