It's no secret that I am a cookie monster. I LOVE cookies, especially Monster Cookies and Monster Cookie Bars.
I also love Monster Cookie Energy Balls. These easy no-bake protein balls taste just like monster cookies, but are a healthy little treat. They only take 10 minutes to make and are the perfect bite size snack.
The ingredients are simple and the balls are so colorful and fun! Kids and adults go crazy for these healthy bites. I always tell the boys I am making them energy balls, but I think I eat as many as they do, ha!
I eat one almost every day after lunch, when I need a little sweet pick me up! They are also good for breakfast on the go, after a workout, a quick snack, or late night dessert.
You can also pack them up and take them on hikes, picnics, or road trips!
The next time you are craving something sweet, make Monster Cookie Energy Balls. They always hit the spot.
Ingredients (with Helpful Notes)
The ingredients are simple, fun, and will remind you of your favorite monster cookies.
- Peanut butter– Make sure you use a creamy, drippy peanut butter. I like natural peanut butter, just peanuts and salt. Stir it really well before measuring. Costco's organic peanut butter is my favorite.
- Honey– to sweeten things up a bit and to help the mixture stick together.
- Vanilla extract– a splash!
- Oats– I use old fashioned oats, but quick oats will work too.
- Protein powder– I add a scoop of vanilla protein powder for an extra boost of protein. Use your favorite brand or swap in collagen powder. Make sure you like the taste because it will affect the taste of the energy balls. And you can make the balls without protein powder, just add in extra oats.
- Flaky sea salt– I love adding sea salt to my cookies and energy balls! The sweet and salty combo is so good!
- Mini chocolate chips & Mini M&M's– I prefer miniature chocolate chips and M&M's for the protein balls, but if you can't find them, regular size will work! And if you don't have M&M's, just use all chocolate chips.
How to Make
You only need 10 minutes! These are the easiest and most delicious snack ever!
- Mix the base. Stir together the peanut butter, honey, and vanilla until smooth. Add the oats, protein powder, and sea salt, mixing until everything is well combined.
- Add the fun stuff. Fold in the mini chocolate chips and M&M's. If the mixture feels a little dry, add a teaspoon or two of water.
- Roll and chill. Roll the mixture into tablespoon-sized balls using your hands or a small cookie scoop. Sprinkle with flaky sea salt if you'd like, then refrigerate until you're ready to snack!
Tips for the Best Energy Balls
Use creamy, well-stirred natural peanut butter. If the peanut butter is dry or thick, the mixture won't hold together as well.
Adjust the texture if needed. Every protein powder absorbs moisture differently, so add a teaspoon of water if the mixture feels crumbly.
Use a small cookie scoop. It makes evenly sized energy balls and speeds up rolling.
Chill before serving. They firm up in the refrigerator and develop the best texture.
Double the batch. They disappear quickly and freeze beautifully.
How to Store
I love having a stash in the fridge or freezer at ALL times!
- Place the energy balls in an airtight container and keep in the refrigerator for up to 2 weeks.
- You can also freeze the balls for up to 2 months. To freeze, place balls on a baking sheet or platter and freeze for 30 minutes or until solid. Remove from the freezer and place in freezer bag or freezer container.
- To serve, you can let them thaw at room temperature for 20 minutes or eat straight from the freezer. They are just as good frozen:)
