- Chocolate Chips – I used Enjoy Life chocolate chips. Semi-sweet is delicious but you could use milk or dark chocolate chips too. You could also use chopped chocolate.
- Protein powder – I used PEScience vanilla protein powder. Protein powders can vary in consistency and some will absorb liquid more easier than others. This might cause your cookie dough mixture to seem a little dry or crumbly. Just add a little water or milk, about a teaspoon at a time, until it gets to cookie dough consistency. Add liquid slowly – you also don’t want to over due it!
- Oat flour – You can always make your own oat flour by grinding up some oats. Or use all-purpose flour if you prefer. If using all-purpose, heat it first (I’ve got more on this in the FAQ section). Coconut flour will not work for this recipe.
- Oats – Old-fashioned is best for thick oat texture. Quick oats will yield a slightly different texture but you can sub in a pinch. Don’t use steel cut oats for this recipe.
- Brown sugar – I used classic golden monk fruit sweetener. Coconut sugar, brown sugar or any brown sugar alternative would work here.
- Peanut butter – use any kind you wish!
- Light butter – or regular butter at room temperature
- Milk – any dairy or nondairy milk work here, we are just using a little.
- Coconut oil
- Salt – A little bit of salt helps bring the flavor out more. Add more or less depending on how salty your peanut butter is.
- M&Ms – I used mini M&Ms.
How To Make
The full printable recipe is below, but let me walk you through the process so you know what to expect when you’re making it!

1. Line an 8×8-inch pan with parchment paper and set aside. Add the chocolate chips to a bowl and heat in 20-30 seconds intervals, stirring in between, until melted.

2. Pour the melted chocolate into the bottom of the pan lined with parchment paper; use a small spatula to spread out evenly. Add to the freezer until the chocolate hardens, about 10 minutes.

3. Meanwhile to a medium-sized bowl, add the peanut butter, butter, oat flour, oats, protein powder, brown sugar and salt. Mix well to combine. Add 1 tablespoon of milk as needed until you get a dough to form, be careful not to add too much!

4. Freeze dough for 5-10 minutes (this helps prevent the candy color from coming off the M&M’s but you can skip if you wish), then fold in half the M&M’s.

5. Add the cookie dough on top of the chocolate layer and spread out evenly/press down well.

6. I used a piece of parchment paper sprayed with nonstick cooking spray to press the dough down and prevent sticking.

7. Add the remainder of the M&M’s across the top and press down one last time.

8. Place back in the freezer for at least 30 minutes before slicing and enjoy. Keep stored in the freezer.
Keep stored in an airtight container in the freezer for 3 months (recommended) or in the fridge for up to one week.
Fun Cookie Dough Variations!
- Nutella protein bars. Instead of peanut butter protein bars, try Nutella protein bars!
- Chocolate chip cookie dough protein bars. Instead of M&M’s, use mini chocolate chips!
- Loaded healthy cookie dough bars. Add in some flax seeds, sunflower seeds or chia seeds for even more health benefits!

What can I use in place of the peanut butter?
You can use cashew butter or almond butter. If allergic to tree nuts, you can use also sunflower butter.
Can I use a different flour?
So I have only tested this recipe with oat flour and all-purpose flour – I have not tried it with almond flour but it should work too. I would not recommend using coconut flour for this recipe.
How to heat treat if using all-purpose flour?
To heat treat flour in the oven, preheat oven to 350 degrees F. Spread the flour onto a baking sheet and bake for 5 minutes, then set aside to cool completely.
To heat treat flour in the microwave, add flour to a microwave safe bowl and microwave in 30 second increments, stirring in between with a rubber spatula until temperature of flour reads 165F with an instant thermometer throughout.
Can I omit the protein powder?
You can. The protein powder does add some sweetness though so taste the dough and add some extra brown sugar (or maple syrup or honey) if needed.
My cookie dough mixture feels too dry/crumbly?
Not all protein powders have the same consistency and some will absorb liquid more easier than others, which might cause your cookie dough mixture to seem a little dry or crumbly. Just add a little water or milk, about a teaspoon at a time, until it gets to cookie dough consistency. Add liquid slowly – you also don’t want to over due it!
