On those busy mornings when you’re just trying to get the kids out the door quickly, these Blackberry Banana Muffins are an easy breakfast or school snack to help you fuel up on the go. I like slathering on some nut butter on mine and enjoying them with a hot cup of coffee!

If I serve these for a quick breakfast for my kids, I like to give them some Greek yogurt or an egg on the side as well for some protein.

If you don’t have blackberries, make these blueberry muffins instead!

For the full recipe with the exact ingredients, scroll down to the printable recipe card below!

STEP 1:

In a high-speed blender or food processor, add all ingredients except for blackberries and process until smooth, being careful not to overmix.

STEP 2:

Using a spoon, gently stir the blackberries into the muffin batter.

STEP 3:

Scoop the batter into non-stick paper liners in a 12-cup muffin pan so they are filled right to or just below the rim. Top each muffin with some banana slices and 1-2 blackberries, if desired.

STEP 4:

Bake in the oven at 350 degrees Fahrenheit for approximately 20 minutes or until a toothpick comes out clean when inserted into the middle of a muffin.

Storage & Reheating

  • Fridge: Store leftover muffins in an airtight container in the fridge for up to 4 days or on the counter for 1-2 days. 
  • Freezer: Allow muffins to cool completely before storing. Once cooled, transfer to a freezer-safe airtight container or freezer bag for up to 3 months. Thaw on the countertop at room temperature or heat the frozen muffin in the microwave until heated through. You may want to heat the muffins in the oven for a few minutes to get them a little crispy/firm on the outside again.

Additions & Substitutions

Additions:

  • Chia seeds
  • Hemp seeds
  • Flaxseed
  • Walnuts

Substitutions:

  • Flour: Instead of a flour mixture, you can just use all-purpose flour and no whole wheat flour if you prefer. You can also use 1:1 Gluten Free Baking Flour to make the muffins gluten-free (you’ll also need to use certified gluten-free oats). If making the muffins gluten-free, I would not use almond flour as that can be a finicky type of flour to work with.
  • Olive oil: You can substitute melted coconut oil (you’ll need 1 cup of coconut oil that will melt down to 1/2 cup).
  • Eggs: You can try replacing the eggs with flaxseed meal to make the muffins vegan. To do this, mix 2 tablespoons flaxseed meal with 5 tablespoons water in a small bowl and let sit for about 5 minutes until it forms a gel-like texture. Add this to the food processor just as you would regular eggs.
  • Blackberries: If you don’t have blackberries on hand, you can use any berries of choice like blueberries, raspberries, or strawberries instead!
  • Rolled Oats: You can use instant oats if you don’t have rolled oats on hand.

Frequently Asked Questions

Can I serve these muffins as a baby-led weaning recipe?

Yes, these are great muffins for babies engaging in baby-led weaning! I would omit the maple syrup, as the banana should act as enough of a natural sweetener for them (you could add a little extra banana). Make sure to use overripe bananas though! Some other great baby-led weaning muffins to try are Spinach Banana Muffins for Toddlers (No Added Sugar!)Healthy Sweet Potato Zucchini MuffinsHealthy Banana Carrot Muffins, and Vegan Apple Cinnamon Muffins. I used the Solid Starts app to help me navigate baby-led weaning and appropriate sizes of food to serve to my little ones.

Can I make this Banana Blackberry Oatmeal Muffin recipe vegan? 

I personally have not tried making these vegan yet, but I think it’ll work by using two flaxeggs instead! To do this, mix 2 tablespoons flaxseed meal with 5 tablespoons water in a small bowl and let sit for about 5 minutes until it forms a gel-like texture. Add this to the food processor just as you would regular eggs. Let me know how it turns out in the comments if you try it this way!

Can I make these muffins gluten-free?

Sure! You can use a 1:1 Gluten Free Baking Flour to make the muffins gluten-free and also be sure that your oats are gluten-free.
