Peanut Butter Protein Bar Ingredients
You’ll only need 4 ingredients for the base and 2 ingredients for the chocolate topping. That’s it! Here’s what you’ll need to make the best protein bars:
- Peanut Butter – Classic creamy peanut butter is the best option for these protein bars. However, almond butter or any type of mixed nut butter works great!
- Vanilla Protein – Plant-based vanilla protein powder or whey vanilla protein powder both work wonderfully in this recipe.
- Almond Flour – Ground almonds, or almond flour, add nutrition and texture to these bars. Other great options include PB2 or more protein powder!
- Maple Syrup – Maple syrup adds the right amount of sweetness to this recipe. Honey or agave syrup also work great!
- Chocolate Chips – Vegan chocolate chips or dark chocolate chips take these peanut butter protein bars to another level.
- Coconut Oil – A touch of coconut oil mixed with the melted chocolate chips create a delicious chocolate glaze topping!
TIP: Add a little bit of flaky sea salt or chopped pistachios on top for an extra crunch!
