Notes
Mint Chocolate Chip Muffins
To make these mint chocolate chip muffins, simply use 1 tsp of mint extract instead and add some vegan chocolate chips to the batter.
You can also use 2-3 drops of mint essential oils instead of the extract if you would like. (Mint oil is very strong, so you only need a tiny amount).
Sprinkle some more chocolate chips on the top before baking for some extra pretty muffins.
Vanilla Hulk Muffins
These are sweet muffins with a beautiful bright green color. Add 2 tsp of vanilla to the batter instead of the mint extract.
You can still add chocolate chips, raisins, or anything that you like to add a little variety to these muffins.
*One batch makes 24 regular-sized muffins or 36 mini muffins.
