Ingredients and Substitutions

You don’t need fancy ingredients or kitchen appliances to make tasty, crunchy homemade protein cookies for your breakfast.

All you need to make high-protein cookies are:

• Old-Fashioned Rolled Oats – or quick oats if you prefer.
• Vanilla Protein Powder – We use plant-based pea protein powder flavored with natural vanilla and naturally sweetened with thaumatin, a natural sweetener found in plants. Since it has only 3 ingredients, this protein powder is very healthy, has no additives, and is perfect to bake protein cookies or make protein shakes.
• Maple Syrup or any liquid sweetener you love like brown rice syrup, agave syrup, or date syrup.
• Dark Chocolate Chips – I like 70%+ cocoa powder chocolate chips, but you can use your favorite ones.
• Peanut Butter or almond butter. For a nut-free options, use sunflower seed butter.
• Mashed Banana or unsweetened applesauce.
• Melted Coconut Oil, avocado oil, light olive oil, or any vegetable oil you have on hands.

How To Make Protein Oatmeal Cookies

1. Preheat the oven to 350°F (180°C) and line a large cookie sheet with parchment paper. Lightly oil the paper with cooking spray. Set aside.

1. In a large mixing bowl, stir the dry ingredients together: oats, protein powder, cinnamon, and salt.

2. In another bowl, add peanut butter, melted coconut oil, mashed banana, and maple syrup. Whisk to bring the ingredients together into a smooth batter.

3. Pour the liquid ingredients into the bowl with the dry ingredients. Stir to combine and form a cookie dough that sticks well together.

4. Fold in dark chocolate chips and stir to incorporate evenly.

7. Use your fingers to gently press down each cookie dough ball. It will lightly crack on the sides, that’s ok use your hands to pack and smooth the edges.

8. Bake in the center rack of the oven for about 17 minutes until golden brown on top.
