Peanut butter has such a moreish flavor that so many of us love.  It’s nutty, sticky, and so satisfying, and when you need a boost of energy, it’s perfect to be added to a bake.

These Peanut Butter Protein Cookies are so quick to make too.  Sometimes we can be put off making our own homemade goodies by the effort required just to get the ingredients out of the cupboard.

Not here – get those 5 things, and you are ready to quickly beat together some energy that you can devour hungrily at any time.  Try dipping into an ice-cold glass of nutty milk!

Ingredients You’ll Need

Rolled oats (1 cup) – Simple traditional ones or ‘old-fashioned’ ones have been used here, but you can use jumbo oats instead if you would like a chunkier texture.

Protein powder (3 tbsp) –  Use any powder you like for this recipe, so there’s no need to buy anything new. Always try and use a good quality one, though, with no added artificial sweeteners.

Peanut butter (1/2 cup) – You can use a crunchy or smooth variety; just make sure it’s a natural one with no added sweeteners. Almond or cashew nut butters are great!

Banana (1) – Use a soft one that’s easy to mash.  The darker yellow, ‘going a bit black’ ones are fine to use, and they will add more natural sweetness to your cookie.

Maple syrup (2 tbsp) –  There are lots of varieties to choose from, so use your favorite.  You could also switch to honey if you prefer.

How to Make Peanut Butter Protein Cookies

Step 1. First, preheat the oven to 350F.  Line a baking sheet with baking parchment and then brush with a little oil if you like.

Place the rolled oats and protein powder into a bowl and stir to combine well.

Step 2. In a separate bowl, mix the peanut butter, mashed banana, and maple syrup until you have a smooth mix.

Step 3. Next, pour the banana and peanut butter mixture over the top of the dry ingredients and stir together.  You may need to knead the dough a little with your hands if it is a little dry.

If your peanut butter isn’t very oily, you could add a little more or add a little more mashed banana.  You need a dough you can make into 12 balls.

Step 4. Place the balls on the prepared baking sheet and space them out evenly.

Step 5. Press down each of the cookie balls with either a spoon or a fork to flatten them out.  You want some lovely cookie shapes!

Step 6. Bake in the oven for 12 minutes or until golden brown. Let the cookies cool down on a cooling rack before serving. This rack is great if you have limited top space!

Can You Use Protein Powder Instead of Flour?

It’s a great idea to replace flour with protein powder as it’s an easy way to pack some extra protein into your diet. This is especially good if you don’t eat meat or struggle to find good quality protein to enjoy.

Well, a little experimentation is needed, but it’s so easy.  When replacing flour for a protein powder, start by replacing 1/3 of your powder for the flour.

So, if you’re using 1 cup of flour, try adding 1/3 cup of your protein powder instead. Mix, mix, mix.  Does it look like a cookie dough?  Can you use a cookie scoop or roll balls?

How Do You Make Peanut Butter Cookies Taste Better?

Simple additions like some dark chocolate chips would be great. little grated orange zest, with or without the chocolate chips, will take the taste up to an even higher level.

How about being really daring and add some earthy ground turmeric to give you a warming taste, anti-inflammatory properties, and a golden glow.

Ground ginger or stem ginger would be a welcome addition for a change and perfect if you’re feeling a little delicate. Dried cranberries or apricots can go well in these cookies, too.

How to Store and Freeze These Cookies

These cookies can be kept for 3-4 days in an airtight container.  If your kitchen is rather warm, it may be better to store them in the refrigerator to keep them fresh.

You could also freeze them if they aren’t snapped up quickly!
