Mix all ingredients together and spoon into an 8x8" pan. Bake at 350 °F for 35-40 minutes. This freezes well too.
Notes
Substitutions
Gluten: Gluten is a protein found in specific grains (wheat, spelt, kamut, barley, rye). Other grains are naturally gluten-free but may have cross-contact with gluten-containing grains. Look for certified gluten-free products if you need to avoid gluten. Find out more about wheat and gluten substitutions.
