Ingredients for High-Protein Cookies
Here’s what you’ll need to make this easy, high-protein snack. See recipe card below for measurements.
- Bananas: You’ll want to use very ripe bananas – the riper the bananas, the sweeter the cookies.
- Oats: Use old-fashioned oats, or quick oats.
- Nut Butter: I used natural peanut butter, but you can also use any nut butter like almond butter, or seed butter if you have nut allergies.
- Vanilla Protein Powder: 1 scoop of your favorite vanilla whey protein powder or pea protein powder adds protein
- Egg: One large egg has 6 grams of protein.
- Salt: a pinch of kosher salt enhances the sweetness
- Flavor: Cinnamon and pure vanilla extract make these breakfast cookies smell and taste amazing.
- Chocolate Chips: I use Lily’s sugar-free chocolate chips, but feel free to use regular semi-sweet chips, dark chocolate chips or dairy-free chips.
