Double Chocolate Protein Muffins


These chocolate protein muffins are fudgy and oh so delicious. There’s no added sugar (sweetened only with bananas) and each muffin has 13 grams of protein! They’re also vegan and gluten-free.

Have you ever made blender muffins? Instead of using a stand mixer or mixing by hand, you can add the ingredients to your blender and mix away! Super simple. One batch makes six muffins, which might not sound like a lot but I think it’s perfect to make them on the weekend and then have one a day for a protein-filled breakfast or snack! Each muffin has 13 grams of protein so they will keep you full all morning long.

I love keeping a healthy sweet treat on hand to satisfy my sweet tooth. Pretty sure baby girl has one too but I have peace of mind knowing these muffins are packed with nutritious ingredients and a solid dose of protein. I don’t have baked goods around too often in our house so when I do make them, I want to make sure they’re 1) delicious and 2) good for me!

Ingredients in Double Chocolate Protein Muffins

  • old-fashioned oats – oatmeal is naturally gluten-free but is often cross-contaminated during processing. If you need these muffins to be gluten-free, make sure you look for oats that say “gluten-free” on the package!
  • bananas – the riper the better here. Bananas add a delicious flavor and help keep the muffins light and moist.
  • chocolate protein powder – you can use your favorite protein powder, but if you want to keep the muffins vegan, make sure you use vegan protein powder. 
  • almond milk – I like to use unsweetened so I can control the amount of sweetener I add to the recipe.
  • flaxseed – we’re actually mixing ground flaxseed with water to make vegan “eggs”. Trust me, it acts as a binding agent.
  • chocolate chips – again, to make this recipe vegan, make sure you grab vegan chocolate chips. I like the Enjoy Life brand.

How to Make Chocolate Protein Muffins

One batch will make six muffins. I’ve tried doubling the recipe to make 12 at once, but it was too much batter for the blender. If you do want to duplicate the recipe, I recommend blending the batter in batches or blending the oats, banana, protein powder and milk together first, transferring to a bowl and mixing everything else together by hand.

But let’s back up… how do you make blender muffins? Start making your flax eggs by mixing the ground flaxseed and water in a small bowl. In a high powered blender, add the oats, banana, chocolate protein powder and almond milk and blend until smooth. Add in the flaxseed eggs, baking soda and baking powder and blend again until combined. Use a spatula to gently stir in the chocolate chips and then scoop the muffin mix into a muffin tin lined with paper or silicone liners. Sprinkle extra chocolate chips on top of each muffin and bake in a preheated oven for 35 to 40 minutes (or until a toothpick comes out clean).

      I followed the comments and only baked for 15mins. They were cooked through already. Also, the measurements above gave me 16 normal sized muffins.

      The bake time is way too long. I cooked them for 35 minutes and they were VERY dry. Can’t decide if it is worth trying again with a shorter cook time. I Should have read the comments first.

      Amazing!!! My toddler loves them as much as i do! I read one of the other comments about the bake time and had the same issue. (Glad i checked them) because they were done at the 15 min mark. We used a regular muffin tin and with this recipe it made us 12 muffins. Maybe this recipe was using the larger muffin tin hence the longer cook time and only making 6?? I dont know but either way they are soooo good! As well as moist, which i was skeptical about. Thank you for always having great recipes!

        Oh no! Sorry about the cook time. I need to test these ones again! Either way, so pumped you loved them! Thanks for the review, Whitney 🙂
