You can certainly add additional flavors to this! Cinnamon (1 tsp), brown sugar (1-2 tablespoons), maple syrup (1 tablespoon), nutmeg (1/4 tsp), lemon zest (zest from half or whole lemon), or even ginger (1/2 tsp) are all delicious options!! You could even add in peanut butter or almond butter (1/4 cup) or chocolate chips (1/4 cup to 1/2 cup)! For chocolate chips, milk, semi-sweet, or dark chocolate chips are all great.
