Notes
Gluten-Free Baking Tips: If time allows, be sure to let the batter rest as hydrating the gluten-free flour is an important step to help eliminate grittiness. You can make batter ahead and store in the fridge up to 1 week until use.DIETARY SUBSTITUTIONSTo make vegan: • In place of the milk, use unsweetened oat, coconut or almond milk. • Swap out butter with vegan butter sticks. My favorite is Country Crock Olive Oil Sticks • To replace the egg, add 1 tsp. soda to the batter with 1 T. vinegar poured on top of the soda.STORAGEGluten-free baked goods do not have the same shelf-life as conventional baked goods. Store in airtight container on counter 1-2 days, refrigerate 3-5 days, or seal in plastic and place in freezer safe container for up to 6 months. When freezing, allow to come to room temperature before opening the container.
