How to Make Monster Cookie Protein Balls
Step 1: Prepare Your Baking Sheet
Line a baking sheet with parchment paper to keep the Monster Cookie Protein Balls from sticking during chilling. This simple setup ensures easy cleanup and helps the balls hold their shape.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine the peanut butter, protein powder, ground flaxseed, salt, maple syrup, milk, and vanilla extract. Stir thoroughly until everything blends into a smooth, sticky mixture that forms the nutritious foundation. Use a sturdy spoon for even distribution.
Step 3: Incorporate Oats and Candies
Add the quick oats, mini M&Ms, and mini chocolate chips to the bowl with the base. Mix again until all ingredients distribute evenly, creating a cohesive dough that’s just right for rolling. This step packs in the fun, colorful elements of no-bake snacks.
Step 4: Roll into Balls
Scoop the dough with a 2-tablespoon cookie scoop or shape by hand into about 18 even balls. Place them on the prepared baking sheet as you go to maintain neat rounds. The mixture should feel tacky but manageable.
Step 5: Chill and Store
Refrigerate the balls for at least one hour so they firm up into chewy, ready-to-eat treats. Once set, transfer to an airtight container and keep in the fridge for up to two weeks. This no-bake method makes them a convenient, healthy treat option.
Pro Tips for Success
- Adjust for Salt: Use unsalted peanut butter and increase salt to 1/4 teaspoon for balanced flavor.
- Opt for Vegan Milk: Swap dairy milk with non-dairy to keep these protein balls fully plant-based.
- Mix Evenly: Stir candies thoroughly to avoid uneven clumps in the chewy dough.
- Chill Fully: Refrigerate at least an hour for firm, non-sticky texture.
How to Serve Monster Cookie Protein Balls
Garnishes
I often roll the finished Monster Cookie Protein Balls in a light coating of crushed nuts for extra crunch. A sprinkle of sea salt on top brings out the peanut butter’s cozy warmth. These simple additions make them feel even more indulgent without much effort.
Side Dishes
Pair these protein balls with sliced apples or bananas to balance the sweetness with fresh fruit. I like serving them next to Greek yogurt for a creamy, protein-rich combo. They also work well alongside carrot sticks for a quick, nutritious afternoon plate.
Creative Ways to Present
For lunchboxes, I tuck a few into a small container with a divider to keep them separate from sandwiches. At gatherings, arrange them on a tray mixed with pretzels for a colorful snack spread. Pressing in edible eyes turns them into playful monster treats for kids’ events.
Make Ahead and Storage
Storing Leftovers
I keep leftover Monster Cookie Protein Balls in an airtight container right in the fridge, where they stay fresh for up to two weeks. This setup prevents them from drying out and makes grabbing one simple. Just check for any softening before serving.
Freezing
Layer the balls between parchment in a freezer-safe bag to freeze for a few months if needed. I thaw them overnight in the fridge to preserve the chewy texture. Avoid refreezing once thawed for best results.
Reheating
These no-bake treats shine at room temperature, so I usually just let them sit out for 10 minutes after the fridge. If you prefer a slight warm-up, microwave one for 5-10 seconds or use a low oven for a minute, covering loosely to retain moisture. This keeps the candies from melting too much.
