Monster Cookie Protein Bars Recipe

Introduction

These Monster Cookie Protein Bars are a delicious and convenient way to fuel your day. Packed with natural peanut butter, protein powder, and colorful mini M&M’s, they make a perfect snack or post-workout treat. Plus, they come together quickly with simple ingredients.

Ingredients

• 1 cup creamy natural peanut butter (must be natural, the kind with oil separating out)
• 5 tablespoons maple syrup
• 1 teaspoon vanilla extract
• ½ cup oat flour
• 60 grams vanilla whey protein powder (about 1/2 cup + 2 tablespoons)
• 1 tablespoon mini chocolate chips
• ¼ cup mini M&M’s

Instructions

1. Step 1: Add the peanut butter, maple syrup, vanilla extract, oat flour, and protein powder to a large bowl.
2. Step 2: Mix everything together with an electric mixer or by hand using a silicone spatula until well combined.
3. Step 3: Fold in the mini chocolate chips and mini M&M’s until evenly distributed throughout the mixture.
4. Step 4: Line a loaf pan or meal prep container with parchment paper. Press the dough firmly into the container using your hands or a spoon to create a thick, even base.
5. Step 5: Cover the container with plastic wrap and place it in the freezer for 1 hour, or until the bars are firm.
6. Step 6: Lift the parchment paper out of the container and cut the firm dough into 6 to 8 bars using a knife.
7. Step 7: Wrap each bar individually and store them in the fridge for up to 1 week or freeze in freezer bags for up to 2 months.

Tips & Variations

• Use gluten-free oat flour if you need a gluten-free option.
• Swap maple syrup for honey or agave syrup to change the sweetness profile.
• Add chopped nuts or seeds for extra crunch and nutrition.
• If you prefer dairy-free, try a plant-based protein powder instead of whey.

Storage

Store the protein bars wrapped individually in the refrigerator for up to 1 week. For longer storage, keep them frozen in airtight freezer bags for up to 2 months. To enjoy, simply thaw bars in the fridge or at room temperature before eating.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use crunchy peanut butter instead of creamy?

Yes, you can use crunchy peanut butter, but the texture will be a bit chunkier. Creamy peanut butter helps the bars hold together more evenly.

What can I use if I don’t have oat flour?

You can make your own oat flour by grinding rolled oats in a blender or food processor until fine. Alternatively, almond flour works but may change the texture slightly.
