Oat Flour Banana Muffins Recipe

These banana oat flour muffins are great for snacks or desserts, and are made with simple ingredients that you can get at all grocery stores. They are sweetened only with bananas, but I provide options below to make them sweeter!

When it comes to baking, oat flour is a really good alternative to refined white flour because it is higher in fiber and nutrients.

Recipe ingredient substitutions

Oat flour substitutions

Instead of store-bought oat flour, you can also make homemade oat flour. To make your own oat flour, simply put rolled oats into a food processor and blend at high speed until you get a fine powder. Use the same amount of ground oats as you would regular oat flour.

You can also mix half oat flour and half rolled oats (or quick-cooking oats) to make oatmeal banana muffins.

If you are celiac or have a gluten intolerance, make sure your oat flour is labelled gluten-free as oats are often cross contaminated with wheat.

Overripe banana substitutions

If you don’t have brown bananas, You can also use regular yellow ripe bananas. I wouldn’t suggest using green bananas though as they are much less sweet and they are higher in starch. You can also use frozen banana pieces, but if you do, take them out of the freezer ahead of time to thaw so that they are easier to mash.

Egg substitutions

Instead of regular eggs, use any egg substitute such as chia, gelatin or flax eggs.

Baking soda substitutions

Instead of 2 teaspoons of baking soda, swap it out for 1 tablespoon of baking powder.

Melted coconut oil substitutions

Instead of melted coconut oil, you can also use light tasting olive oil, avocado oil, vegetable oil, melted vegan butter or regular butter if you tolerate dairy.

Recipe variations

Make this recipe without a food processor or stand mixer

If you don’t own a stand mixer, food processor or high powered blender, you can still make this recipe with a large mixing bowl and potato masher. Remove the peels from your bananas and put them in your large bowl. Using your potato masher, mash the bananas until you get them into a smooth paste. Don’t worry about the odd remaining lump. Then follow the rest of the recipe as is below.

Make banana chocolate chip muffins

Follow the recipe as is, but once you’ve got your muffin batter ready, add anywhere from 1/2 – 3/4 cup of dark chocolate chips.

Make oat flour banana bread

You can easily make this recipe into bread by following my oat flour banana bread recipe.

Make your banana muffins sweeter

These muffins are sweetened only with bananas, but if you want them to be even sweeter, consider adding a small amount of maple syrup, brown sugar, cane sugar, coconut sugar, or honey. You can even use a little bit of apple sauce to sweeten them up with fruit only.

Dietary modifications

Make this recipe vegan

Swap out the regular eggs for vegan egg substitutes such as chia or flax.

Make this recipe paleo/grain free

Swap out the oat flour for either almond flour or cassava flour. If you use cassava flour, use around 1 – 1 1/4 cup because it absorbs more liquid than oat flour does. You can also check out my paleo banana muffins recipe or paleo cassava flour banana bread recipe.

Recipe pairings

These banana muffins pair great with:

• peanut butter, almond butter or any other nut butter
• jam
• a big glass of almond milk (or regular milk if you tolerate dairy)
• your morning coffee
• butter (vegan or regular)

Meal prep this recipe

If you are preparing this recipe for snacks during the week, make a second batch of muffins by doubling the recipe. You’ll need 2 muffin pans and 24 muffin liners.

Storage and reheating tips

Store your leftover muffins in an airtight container in the fridge for 3-4 days. Pro tip: Microwave them for 30 seconds when you are ready to eat them. This will make them super moist and warm like they are right out of the oven.

To keep them longer, store them in a freezer-safe container in the freezer for up to 3 – 6 months. When you are ready to eat them, take them out of the freezer and let them thaw in the fridge for 24 hours, or on the counter for 4 hours or so. Reheat them in the microwave for 30 seconds to make them super moist and warm.
