How to Make Easy No-Bake Monster Protein Cookie Dough Bars
-
Prepare the Pan: Line an 8×8-inch square pan with parchment paper, ensuring it hangs over the edges for easy lifting later. This step is essential for easy removal of your delicious bars!
-
Melt the Chocolate: Combine the semi-sweet chocolate chips and coconut oil in a microwave-safe bowl. Heat in intervals, stirring until smooth and melted. Spread this luscious mixture evenly in the bottom of the prepared pan, then freeze for about 10 minutes until firm.
-
Mix the Dough: In a mixing bowl, blend the peanut butter, light butter, oat flour, old-fashioned oats, protein powder, brown sugar, and a pinch of salt. Add milk incrementally to achieve a dough-like consistency that’s thick but not crumbly.
-
Incorporate the M&Ms: Optionally freeze the dough for 5-10 minutes to prevent the M&M colors from bleeding. Then, fold half of the mini M&Ms into the dough for delicious bursts of color and sweetness.
-
Assemble the Bars: Spread the cookie dough mixture over the chilled chocolate layer, pressing firmly so it sticks. Don’t be shy—use enough pressure to create a nice compact layer!
-
Top It Off: Sprinkle the remaining M&Ms on top of the cookie dough and gently press them down into the mixture, making sure they’re well embedded.
-
Chill: Freeze the entire pan for at least 30 minutes to allow the bars to firm up nicely. This will make slicing easier and keep everything together!
Optional: Drizzle with extra melted chocolate for a delightful finish.

Easy No-Bake Monster Protein Cookie Dough Bars Recipe FAQs
How do I choose the right peanut butter?
Absolutely! For the best flavor in your Easy No-Bake Monster Protein Cookie Dough Bars, select a natural peanut butter with minimal added ingredients, ideally just peanuts and salt. Avoid brands with added sugars or hydrogenated oils for a healthier option. If you have nut allergies, almond butter or sunflower butter work wonderfully as substitutes!
What’s the best way to store these bars?
I often store my bars in an airtight container in the refrigerator for up to 1 week. This helps maintain their chewy texture. For longer storage, freeze them in an airtight container or wrapped individually in plastic wrap for up to 3 months. When you’re ready to enjoy, simply thaw them in the fridge overnight!
Can I freeze these bars, and how?
Absolutely! To freeze your Easy No-Bake Monster Protein Cookie Dough Bars, wrap them tightly in plastic wrap or place them in a freezer-safe container. Make sure to separate layers with parchment paper to avoid sticking. They’ll keep well for up to 3 months. When you’re ready to indulge, let them thaw in the refrigerator for about 2-3 hours for the best flavor and texture.
What can I do if my dough is too crumbly?
No worries! If your dough turns out crumbly, it might need a little more moisture. Gradually add more milk, one tablespoon at a time, until the mixture reaches a thick but pliable consistency. Ensure you’re using the correct amounts of dry ingredients, and remember that ambient humidity can affect texture, so adjust accordingly!
Are there any dietary considerations I should be aware of?
Very much so! These bars can be made gluten-free by using certified gluten-free oats and oat flour. For a dairy-free or vegan option, substitute regular butter with vegan butter and use dairy-free chocolate. Always check the labels for any potential allergens, especially if you’re sharing these treats with friends or family who might have dietary restrictions.
