What makes these healthy monster cookies delicious & healthy
- rolled oats
- ripe bananas
- natural peanut butter
- semi-sweet chocolate chips
How to make these monster cookies
Start by preheating your oven to 350°F and lining a baking sheet with parchment paper, a silicone baking mat, or spraying with cooking spray.
In a large bowl, combine 1 1/2 cup of rolled oats, 2 teaspoons of cinnamon, and 1/4 teaspoon of salt.
In a separate bowl, mash together 1 1/2 ripe bananas, then stir in 2 teaspoons of vanilla, and 1/3 cup natural peanut butter (either creamy or chunky works!). Stir in 1/3 cup semi-sweet chocolate chips.
Drop the dough by the spoonful onto your prepared baking sheet. (should make about 12 cookies) Flatten and shape cookies with your hands or a spoon to make make even rounds. Top each cookie with M&Ms, and bake in preheated oven for 10-12 minutes, or until firm. Let cool for 5 minutes on baking sheet before moving to a wire cooling rack to cool completely. Store in an airtight container for up to 4 days, or freeze up to a month.
- Don’t add the M&Ms until AFTER you add your cookies to your baking sheet. Mixing them into the wet batter will make their coating and color wear off, and = ugggly cookies.
- Use SUPER ripe bananas for these for extra sweetness. I usually just microwave frozen ripe bananas before mashing and mixing.
- Bake the cookies until they are firm to help them keep their shape.
My cookies aren’t holding together. What went wrong?
These cookies take a little extra TLC to keep them in line. After dropping by the spoonful on your baking sheet, I will spray my hands with cooking spray, and form them into rounds. Press them together to help make sure all the ingredients are formed together. Do this BEFORE adding M&Ms.
My M&Ms look capital F FUNKY. What happened?!
You probably mixed them into your batter instead of adding to the top of the cookies. This cookie dough is much wetter than traditional cookie dough, and will cause the colorful coating to come off your M&Ms if you mix them in. To keep this from happening, add your M&Ms to the tops of your cookies after adding to the baking sheet, forming, and before baking.
How long do these cookies last?
I find that the longer they sit, the more the color of the M&Ms wear off, so a good 4 days is probably best. They will still taste the same, but won’t look as pretty. You can also freeze them for up to a month.
Money Saving Tips for this Healthy Monster Cookie Recipe:
- Buy a small bag of M&Ms. You know what will happen if you buy the big honkin’ bag of them. Unless you’re baking oodles of these cookies, buying a single serve pack of M&Ms will be enough for this recipe, and will save some $$$.
- Use store brand. Most supermarkets have their own brand of chocolate chips and natural peanut butter now, and are most often cheaper than name brands with no taste difference.
- Buy oats in bulk. These are one of the items I like to buy a big canister of since I always use them later on, especially in these oat bites, or a batch of savory overnight oats. Buying the bigger container ends up giving you more for your money.
