Ingredients
• 1 cup creamy peanut butter (smooth style works best; trial almond or sunflower seed butter for a twist)
• 2 cups old-fashioned rolled oats (certified gluten-free if needed)
• ½ cup honey or pure maple syrup (honey gives a chewier texture)
• 1 teaspoon pure vanilla extract (look for Nielsen-Massey or similar)
• ¼ teaspoon kosher salt (balances sweetness)
• 2 tablespoons unsalted butter (optional—for extra richness)
• ½ cup mini semi-sweet chocolate chips (Ghirardelli or Nestlé are great)
• ½ cup M&M’s (regular or peanut-free for school snacks)
• 2 tablespoons unsweetened shredded coconut (optional topping)
Tip: Scoop your peanut butter from room temperature for easy stirring. Measure oats loosely—no compaction.
Directions
- Line a baking sheet with parchment paper. This catches drips and saves cleanup time.
- In a medium saucepan over low heat, melt peanut butter, butter, and honey together. Stir gently until silky and homogenous—about 2–3 minutes.
- Remove from heat; whisk in vanilla extract and salt. You’ll notice a lovely nutty aroma—hello, comfort food!
- Transfer the warm mixture into a large mixing bowl. Fold in the oats with a sturdy spatula, ensuring every flake is coated. They’ll look glossy and soft.
- Add chocolate chips and M&M’s. Stir until bits are evenly distributed—trust me, you want color in every bite.
- Let the mixture rest for 5 minutes so it cools slightly and thickens—this helps the cookies hold their shape.
- Scoop rounded tablespoons of dough and place them on the parchment, spacing about 1 inch apart. Press lightly for a flatter cookie.
- If you like, sprinkle shredded coconut or extra chocolate chips on top. A little flair goes a long way.
- Chill the sheet in the fridge for at least 30 minutes (or freezer for 15) until firm. If you skip chilling, cookies may crumble.
- Once set, transfer the Monster Cookies to an airtight container. Try not to eat them all at once—though it’s tempting.
Servings & Timing
Yield: Makes 18–20 cookies
Prep Time: 15 minutes
Chill Time: 30 minutes
Total Time: About 45 minutes
These cookies keep snack crises at bay. A quick afternoon pick-me-up never looked so bright.
Variations
• Almond Butter Monster Cookies: Swap peanut butter for almond butter.
• Double-Chocolate: Stir in white chocolate chips with dark ones.
• Nut-Free: Use sunflower seed butter and skip M&M’s or choose allergy-friendly candies.
• Tropical Twist: Add ¼ cup chopped dried pineapple or mango.
• Protein Boost: Toss in 2 tablespoons chia seeds or hemp hearts.
• Peppermint Crunch: Swap M&M’s for crushed peppermints at holiday time.
Storage & Reheating
Store cookies in an airtight container in the fridge for up to 7 days. Freeze for up to 3 months—just layer with parchment between batches. Thaw at room temperature for 10–15 minutes before serving. Make-ahead tip: Prepare the dough, shape into balls, then freeze on the tray. When you’re ready, pop them in the fridge to chill—it takes about 30 minutes straight from frozen.
Notes
• Texture tweak: For chewier cookies, swap half the oats for quick oats.
• If your mixture seems dry, add a teaspoon of milk (dairy or plant-based) until it sticks.
• Overmixing cool dough can crush chips—stir gently once the mixture is below 100°F.
• I like my cookies slightly thicker; pressing too flat makes them crumbly.
• If you’re packing these for lunches, wrap individually in wax paper to keep M&M’s intact.
FAQs
Q: Can I use quick oats instead of rolled oats?
A: Yes—quick oats work, but cookies will be denser and less textured.
Q: Are Monster Cookies vegan?
A: To go vegan, swap honey for maple syrup and use dairy-free chocolate chips.
Q: My cookies fell apart. What happened?
A: Likely they weren’t chilled long enough or the binder ratio was off; try an extra minute of heat for peanut butter and honey.
Q: Can I cut the sugar?
A: You could reduce honey to ⅓ cup, but they’ll be less sweet and slightly drier.
Q: What scoop size should I use?
A: A 1-tablespoon cookie scoop makes uniform, bite-sized treats.
Q: How do I make these school-safe?
A: Choose peanut-free butter and allergy-friendly candy blends.
Q: Can I grill these?
A: Not recommended—they’ll melt too quickly. Stick to chilling for best shape.
