Ingredients needed

Oatmeal muffins use affordable ingredients, many which are right in your kitchen. I typically havehomemade yogurton hand, but if are looking for a dairy-free recipe you may also substitute unsweetened applesauce.

  • Oats – These are used to first blend into flour and then stirred in at the end for a heartier texture. When baking recipes for a GF diet, from these gluten-free muffins to homemade chewy gluten-free granola bars, be sure to use certified GF oats.
  • Brown sugar – Adapt the amount for a low-sugar recipe or use your favorite unrefined sugar.
  • Baking powder
  • Baking soda
  • Ground cinnamon
  • Salt
  • Yogurt – For dairy-free substitute the same amount of unsweetened applesauce. This works well for other oat flour recipes, such as gluten-free biscuits made with oatmeal.
  • Egg
  • Canola oil or coconut oil
  • Milk or dairy-free substitute
  • Vanilla extract

  • Oat Flour Chocolate Chip Muffins – Stir in one cup chocolate chips. I like to use a mixture of semi-sweet and mini chips with more chips sprinkled on top for a true bakery-style muffin!
  • Oat Flour Berry Muffins – Add 1 1/2 cups blueberries, raspberries, blackberries, or a mixture after the batter has been blended.
  • Banana Nut – To make banana oatmeal muffins either replace the oil with one mashed banana or add 1 cup chopped bananas and 1/2 cup nuts to the batter.
  • Apple Oat Flour Muffins – Replace the yogurt in the recipe with an equal amount of unsweetened applesauce and stir in 1 cup shredded apple after the batter has been blended. The batter will contain a little more moisture, so you might need to bake them 1-2 minutes longer. Alternatively, follow this applesauce muffins recipe, replacing the flour with gluten-free flour.
