Hardware & Gadgets
Before you start baking, gather the following tools:

From Start to Finish: Monster Magic Cookie Bars

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Monster Magic Cookie Bars bake evenly and thoroughly.
Step 2: Prepare the Baking Dish
Grease your 9×13-inch baking dish with a little cooking spray or line it with parchment paper for easy removal later.
Step 3: Make the Crust
In a mixing bowl, combine the graham cracker crumbs and melted salted butter. Stir until the mixture is well combined and resembles wet sand. Press this mixture firmly into the bottom of your prepared baking dish to create an even layer.
Step 4: Layer the Goodies
Evenly sprinkle the old-fashioned oats over the graham cracker crust. Next, pour the sweetened condensed milk over the oats, ensuring an even distribution.
Step 5: Add the Chips and M&Ms
Sprinkle the peanut butter chips, chocolate chips, and mini M&Ms over the top of the condensed milk layer. Use a spatula to gently press them down into the mixture to ensure they stick.
Step 6: Bake
Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the edges are golden brown and the center is set. The bars will continue to firm up as they cool.
Step 7: Cool and Cut
Once baked, remove the dish from the oven and let it cool completely on a wire rack. After cooling, use a sharp knife to cut the bars into squares or rectangles.
Step 8: Serve and Enjoy
Your Monster Magic Cookie Bars are now ready to be enjoyed! Serve them at room temperature or slightly chilled for a delightful treat.
Substitutions by Diet

If you’re looking to adapt this recipe for different dietary needs, consider the following substitutions:
- Gluten-Free: Use gluten-free graham cracker crumbs.
- Dairy-Free: Substitute the butter with coconut oil or dairy-free butter and use dairy-free chocolate chips.
- Nut-Free: Replace peanut butter chips with butterscotch chips or omit them entirely.
- Less Sugar: Use unsweetened almond milk or any plant-based milk to reduce sweetness and calories.
Mistakes That Ruin Monster Magic Cookie Bars
Creating Monster Magic Cookie Bars is relatively straightforward, but a few common mistakes can lead to less-than-perfect results:
- Not packing the crust: Ensure you press the graham cracker crust firmly into the dish; a loose crust may crumble when cut.
- Overbaking: Keep an eye on the bars as they bake; overbaking can lead to dry bars.
- Skipping the cooling step: Allow the bars to cool completely before cutting; this helps them set properly.
- Using the wrong size baking dish: A dish that’s too small can lead to overflow, while one that’s too large may lead to uneven baking.
Save for Later: Storage Tips
To keep your Monster Magic Cookie Bars fresh and delicious, follow these storage tips:
- Room Temperature: Store in an airtight container at room temperature for up to 5 days.
- Refrigeration: For longer storage, place the bars in the fridge, where they can last for up to 2 weeks.
- Freezing: Wrap individual bars in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw at room temperature before enjoying.
Handy Q&A
Can I use a different type of milk?
Yes! While sweetened condensed milk is key to the texture of these bars, you can experiment with different varieties like coconut or almond milk. Just be aware that the texture may differ slightly.
What’s the best way to cut the bars?
For neat squares, use a sharp knife and wipe the blade with a damp cloth between cuts. This prevents sticking and makes for cleaner edges.
Can I add other mix-ins?
Absolutely! Feel free to get creative by adding chopped nuts, shredded coconut, or any of your favorite candies. The more, the merrier!
How do I know when the bars are done baking?
Look for a golden-brown edge and a slightly set center. The bars will firm up as they cool, so don’t worry if the center seems a bit soft when you pull them out of the oven.
