What to Buy

1 cup creamy natural peanut butter: Costco brand is my favorite for its smooth texture and rich flavor.
1/3 cup honey: This natural sweetener adds a lovely sweetness and helps bind the ingredients.
1 teaspoon pure vanilla extract: For that aromatic essence that elevates the flavor.
2 cups old fashioned oats: They provide a hearty base and chewy texture.
1/4 cup vanilla protein powder: Optional, but it adds a protein boost and creaminess.
1/2 teaspoon flaky sea salt: To enhance the flavors and create a delightful contrast.
1 cup semi-sweet chocolate chips: Essential for that melty chocolate goodness.
1 tablespoon coconut oil: Helps to bind the ingredients together and adds a hint of tropical flavor.
2 to 3 tablespoons M&Ms: For a pop of color and sweetness in every bite.
Flaky sea salt for sprinkling on top: A finishing touch that elevates the bars.

Gear Up: What to Grab

Mixing bowl: A large bowl for combining all the ingredients.
Spatula: For mixing everything together and ensuring no ingredient is left behind.
9×9 inch baking pan: To set your bars in and create the perfect shape.
Parchment paper: To line the baking pan, making it easier to lift the bars out later.
Measuring cups and spoons: Accurate measurements are key to a successful recipe.

From Start to Finish: No Bake Monster Cookie Bars

Step 1: Prepare Your Pan

Start by lining a 9×9 inch baking pan with parchment paper. This will make it easier to cut and remove the bars once they are set.

Step 2: Mix the Wet Ingredients

In a large mixing bowl, combine 1 cup of creamy natural peanut butter, 1/3 cup honey, and 1 teaspoon pure vanilla extract. Stir until it’s smooth and well combined. The warmth of the peanut butter and honey will help them blend seamlessly.

Step 3: Add the Dry Ingredients

Next, add in 2 cups of old fashioned oats, 1/4 cup vanilla protein powder, and 1/2 teaspoon of flaky sea salt. Mix everything together until the dry ingredients are fully incorporated into the wet mixture. You’ll want a thick, dough-like consistency.

Step 4: Fold in the Chocolate and M&Ms

Gently fold in 1 cup of semi-sweet chocolate chips and 2 to 3 tablespoons of M&Ms. Make sure they are evenly distributed throughout the mixture for a delightful surprise in every bite.

Step 5: Press into the Pan

Transfer the mixture to the prepared baking pan. Using a spatula, press the mixture firmly and evenly into the pan. This step is crucial for the bars to hold their shape once cut.

Step 6: Chill to Set

Place the pan in the refrigerator for at least 30 minutes to allow the bars to firm up. This will make cutting them much easier.

Step 7: Cut and Serve

Once set, remove the bars from the pan using the parchment paper. Cut into squares or rectangles, sprinkle with flaky sea salt on top, and serve. Enjoy your delicious No Bake Monster Cookie Bars!

Seasonal Ingredient Swaps

Nut butters: Swap peanut butter for almond butter or sunbutter for a nut-free version.
Sweeteners: Use maple syrup instead of honey for a vegan option.
Protein powder: Try chocolate protein powder for a richer flavor.
Mix-ins: Substitute M&Ms with dried fruits, nuts, or seeds for a different twist.

What Not to Do

Don’t skip lining the pan with parchment paper; it makes removing the bars a breeze!
Avoid using quick oats instead of old fashioned oats, as they may not provide the same texture.
Be sure to press the mixture firmly into the pan; loose bars will crumble when cut.
Do not forget to chill the bars long enough for them to set properly; this is key for the perfect cut!
