🍌What you will need
📃Notes /substitutions
- Protein powder - I recommend sticking to an unflavored and unsweetened one, if possible. If you are using one that is sweetened, you might need to cut back on maple syrup used. I am personally using this Naked pea protein powder, and am currently loving it.
- Maple syrup - Feel free to use other liquid sweetener in place like agave syrup or a few drops of stevia.
- Peanut butter - To make this peanut free, substitute with other nut butter like almond or cashew butter. You can even make them totally nut free by using sunflower seed butter or tahini.
- Gluten-free - Make sure to use oats and protein powder that are certified gluten-free.
🔪How to make
Preheat oven to 180C/350F.
In a large mixing bowl, mash banana with a fork or potato masher until smooth.
Next, add in maple syrup and peanut butter. Stir until everything is well combined.
Now, add in protein powder, oats, chocolate chips and baking powder. Mix well. The mixture should resembles cookie dough, so do add a splash of water or more protein powder if needed.
Portion out around ¼ cup of mixture and roll it into a ball. Gently flatten the dough using your palm. Repeat until the dough is used up.
Bake for 8-10 minutes, or until cookies appears firm and set. Let your vegan protein cookies cool down slightly before enjoying!
✔Helpful tips
- Use ripe bananas. The spottier and browner the banana, the better! As they will be the main sweetener in this banana protein cookies, you will want them to be ripe and sweet.
- Make sure to use natural peanut butter, the type that only contains peanut and salt without oil.
- As the absorbance of protein powder varies from type to type, you might need to add a splash of water or more protein powder. The mixture should resembles cookie dough.
- Slightly flatten out your cookies when shaping. These vegan protein cookies do not expand much after baking.
✨Variations
- Chocolate flavored - Use a chocolate flavored protein powder, and add in a few tablespoons of cocoa or cacao powder.
- Oatmeal raisin - Substitute chocolate chips with equal parts raisin instead.
- Feel free to mix in any spices or flavorings that sounds good. Cinnamon powder, vanilla extract and nutmeg are some great add-ins.
- Switch up the flavor by simply changing the flavor of protein powder used. I had tried using salted caramel and vanilla protein powder in the past, and they turn out to be great!
❔Commonly asked questions
You can definitely make these banana protein cookies without peanut butter, but you will need to swap it for something else. The best substitute is another kind of nut or seed butter, like almond butter, cashew butter, sunflower seed butter or tahini.
Do keep in mind that depending on the kind of nut/seed butter used, the flavor will change slightly.
These vegan protein cookies are naturally free from gluten. Cross contamination may occur during the processing of oats or protein powder, so do double-check if they are certified if you are intolerant to gluten.
Store leftover peanut butter oatmeal protein cookies in a sealed container. They should stay well in the fridge for a week, and in the freezer for up to 3 months.
To reheat, let frozen cookies thaw completely in the fridge overnight, or by using the 'thaw' function of your microwave oven. You can then proceed on to heat them in an oven at 200C for 8-10 minutes, or in the microwave for 15-30 seconds.
