Ingredients

  • 1 ½ cups gluten-free protein oats I used @bobsredmill
  • 1/3 cup vanilla protein powder Ritual is one of my go-to’s
  • 1 teaspoon cinnamon
  • ½ teaspoon baking powder
  • ¼ teaspoon sea salt
  • 1 cup unsweetened almond milk
  • 1 large egg
  • 2 tablespoons maple syrup or raw honey
  • 1 teaspoon vanilla extract
  • 2 tablespoons peanut butter optional
  • 1 cup fresh or frozen mixed berries

Instructions

  • Preheat the oven to 350°F. Grease or line a muffin tin.
  • In a large bowl, combine oats, protein powder, cinnamon, baking powder, and salt.
  • In a separate bowl, whisk together almond milk, egg, maple syrup, vanilla extract, and almond butter.
  • Pour the wet mixture into the dry and stir until combined. Gently fold in the berries.
  • Divide the mixture evenly among the muffin cups, filling each about ¾ full.
  • Bake for 25-27 minutes, until golden and set in the center.
  • Let cool before removing from the tin. Store in the fridge or freeze for later. Enjoy!

Notes

Easy Swaps & Substitutions
  • Milk: Swap almond milk with oat, coconut, or regular dairy milk.
  • Sweetener: Use honey instead of maple syrup.
  • Nut butter: Sub almond butter for peanut butter—or skip it entirely.
  • Fruit: Don’t have mixed berries? Try chopped apples, bananas, or dark chocolate chips.
  • Vegan option: Use a flax egg + plant-based protein powder.
No Protein Powder? Try These Substitutes
To keep the protein content high:
  • Greek yogurt: Use ½ cup in place of 1/3 cup protein powder; reduce almond milk slightly.
  • Cottage cheese (blended): Same as Greek yogurt—use ½ cup and reduce milk a bit.
  • Liquid egg whites: Add ¼–⅓ cup and slightly reduce almond milk.
For lower-protein versions:
  • Almond flour or oat flour: Use a 1:1 ratio to replace protein powder.
  • Extra oats: Add an additional ¼ cup oats in place of protein powder.
Tip: Always use a clean-label protein powder for best taste & texture. See My 6 Favorite Protein Powders HERE.
