Monster Cookie Bars Oatmeal Chocolate

Monster Cookie Bars always have a way of bringing instant joy to a table They are loaded with oats peanut butter chocolate and those colorful bits of candy that always catch a kid’s eye One pan feeds a crowd and the result is chewy buttery and packed with sweet and salty goodness It is my go-to for bake sales birthday parties or those days you just want something comforting and fun

I remember the first time I made these I walked into the kitchen to find my kids sneaking bites before they even cooled Now we cannot get through a holiday without making a batch

Ingredients

• Butter at room temperature: makes your bars tender and rich Look for a creamy texture and a sweet milk aroma
• Light brown sugar: adds a touch of caramel flavor and gives a chewy softness Check for fresh soft sugar that clumps slightly under your fingers
• White sugar: balances sweetness and helps create crisp edges Choose fine granulated sugar for even mixing
• Eggs: bind all the ingredients together and give structure Use large eggs at room temperature for best texture
• Baking soda: helps the bars rise just enough so they are not too dense Make sure it is fresh for good lift
• Vanilla extract: gives warmth and a bakery-style aroma Pure extract brings out the best flavor
• Maple syrup: brings depth and an extra note of sweetness Use real syrup for that unmistakable taste
• Crunchy peanut butter: adds flavor and wonderful bits of peanut throughout Choose a jar with nuts listed high on the ingredient list for the best crunch
• Old fashioned oats: give hearty texture and chewiness Avoid quick oats for better structure
• Semi sweet chocolate chips: deliver gooey chocolate in every bite Use good quality chips for smooth melting
• M and M candies: create a festive colorful topping I like grabbing seasonal colors for special occasions

Step-by-Step Instructions

Beat the Butter and Sugars:

Cream the butter with both sugars in a large bowl using a hand or stand mixer Keep mixing until it looks fluffy and pale This is what makes your bars tender and helps everything blend smoothly

Add the Eggs and Flavorings:

Crack in the eggs then pour in the vanilla extract maple syrup and sprinkle in the baking soda Beat again until you have a thick glossy mixture The maple syrup adds moisture and a hint of richness

Incorporate the Peanut Butter:

Spoon in the crunchy peanut butter and mix thoroughly The mixture will look thick and creamy with little bits of peanut visible throughout

Add Oats and Chocolate Chips:

Pour in all the oats and stir slowly to avoid flour flying out Mix until the oats are evenly coated and distributed Add the chocolate chips last and gently fold them in to keep them whole

Press Dough into Pan and Add M and Ms:

Scoop the dough into a parchment lined large baking sheet or jelly roll pan Press it down with your hands or a spatula so it reaches every corner Scatter the M and Ms over the top and press lightly so they adhere but do not sink too deep

Bake to Perfection:

Slide the pan into the oven at three hundred fifty degrees F Bake for about sixteen to seventeen minutes Watch for the top to look just dry around the edges but slightly shiny and soft in the center They will firm up as they cool so do not overbake

Cool and Slice:

Allow the bars to cool completely in the pan This step is key They finish setting up as they cool and slicing is easier when they are firm
