Gluten-Free Monster Oat Bars
Easy no-bake bars combining peanut butter, chocolate, oats, and colorful M&Ms. These chewy, chocolatey treats are perfect for lunch boxes, parties, or anytime you crave something sweet. Ready in just 30 minutes with simple pantry ingredients.
Equipment
- 8x8 inch baking dish
- Microwave-safe bowl
- Offset spatula
Ingredients
- 2 ½ cups gluten-free rolled oats
- ½ cup honey or maple syrup
- 1 cup creamy peanut butter divided (¾ cup + ¼ cup)
- 1 cup mini chocolate chips
- 1 ½ cups dark or milk chocolate chips for melting
- ½ cup mini M&Ms gluten-free
Instructions
- Make the Base: In a medium saucepan over low heat, stir together honey and ¾ cup peanut butter until smooth and combined. Remove from heat and stir in oats until fully coated. Mix in mini chocolate chips.
- Press Into Pan: Line an 8x8-inch baking dish with parchment paper. Firmly press the oat mixture into the bottom of the pan to form an even layer.
- Top with Chocolate + PB: Melt chocolate chips in a microwave-safe bowl in 20–30 second intervals, stirring until smooth. Pour over oat base, spreading evenly. Drizzle remaining ¼ cup peanut butter over chocolate layer.
- Add Candy: Sprinkle mini M&Ms evenly across the top. Gently press them into the chocolate so they stick.
- Chill & Slice: Refrigerate for at least 1–2 hours, or until chocolate is set. Lift out using parchment, cut into squares, and serve.
