How to Make Big Giant Monster Cookies
Prep Dry Ingredients: In a large bowl, whisk together the flour, oats, baking soda, and salt. This helps ensure an even distribution of dry ingredients throughout your cookie dough, creating the perfect blend of flavors and textures.
Cream Butter and Sugars: In your stand mixer, beat the softened butter with granulated sugar and brown sugar until the mixture is light and fluffy, about 3-5 minutes. This step is crucial for incorporating air into the mixture, contributing to the cookie s delightful texture.
Mix in Wet Ingredients: Add in the eggs, peanut butter, and vanilla extract to the butter-sugar mixture, and mix until fully incorporated. You want a smooth, creamy consistency this richness will give your cookies their signature taste.
Combine Ingredients: Gradually blend in the flour mixture until just combined. Then, fold in the oats, chocolate chips, and Mini M&Ms until a thick dough forms. This gentle folding helps retain the airiness from the creamed butter and sugars.
Chill Dough: Refrigerate the dough for at least 30 minutes before baking. This helps enhance the flavor and improves the texture by preventing excessive spreading during baking.
Portion & Bake: Scoop the dough using a cookie scoop (about 65g each) and place it on a parchment-lined baking sheet. Bake in a preheated oven at 350 °F (175 °C) for about 15 minutes, or until the edges are lightly golden.
Optional: Drizzle with melted chocolate for an extra indulgent touch!
