INGREDIENTS YOU’LL NEED:
- Gluten-free protein oats
- Vanilla protein powder
- Cinnamon
- Baking powder
- Sea salt
- Unsweetened almond milk (or other milk)
- Egg (or flax egg for vegan)
- Maple syrup or raw honey

HOW TO MAKE HEALTHY BERRY OATMEAL PROTEIN MUFFINS
Preheat the oven to 350°F. Grease or line a muffin tin.
In a large bowl, combine 1 ½ cups gluten-free protein oats, 1/3 cup vanilla protein powder, 1 teaspoon cinnamon, ½ teaspoon baking powder, and ¼ teaspoon sea salt.
In a separate bowl, whisk together 1 cup unsweetened almond milk, 1 large egg (or flax egg), 2 tablespoons maple syrup or raw honey, 1 teaspoon vanilla extract, and 2 tablespoons peanut or almond butter (optional).
Pour the wet ingredients into the dry and stir until combined. Gently fold in 1 cup fresh or frozen mixed berries.
Divide the batter evenly among 6 muffin cups, filling each about ¾ full. Bake for 25–27 minutes, until golden and set in the center.
Allow the muffins to cool before removing from the tin. Store in an airtight container in the fridge for up to 5 days or freeze for up to 2 months. Reheat briefly in the microwave or toaster oven to enjoy warm.
RECIPE SUBSTITUTIONS & QUESTIONS
These muffins are flexible—swap ingredients based on what you have:
- Milk: Use oat, coconut, or regular dairy milk instead of almond milk.
- Sweetener: Substitute honey for maple syrup.
- Nut butter: Use almond butter in place of peanut butter or omit it.
- Fruit: If you don’t have mixed berries, try chopped apples, bananas, or dark chocolate chips.
- Vegan: Use a flax egg and plant-based protein powder.
If you don’t have protein powder but still want higher protein, try ½ cup Greek yogurt or ½ cup blended cottage cheese (reduce milk slightly), or add ¼–⅓ cup liquid egg whites. For lower-protein substitutions, replace the protein powder with a 1:1 amount of almond or oat flour, or add an extra ¼ cup oats.
