Thick and chewy monster cookies that are loaded with peanut butter, oats, chocolate chips, and m&m’s are sure to be a hit with your family!
I remember my mom making these Monster Cookies when I was in high school and I couldn’t get enough of them back then! These cookies are dense, moist and very filling!
Can you freeze monster cookie dough if you don’t want to bake the whole batch?
Absolutely! I like to scoop my dough out onto parchment-lined cookie sheets and press each dough ball into a flattened thick disc, like a hockey puck. Place pan in the freezer and freeze them overnight. Once frozen solid, I remove them from the paper and drop them into zip top freezer bags and freeze them until I’m ready to bake. They can bake from the frozen state in a preheated oven.
Tips for the Monster Cookies:
- Make sure to soften your butter but do not melt the butter.
- Creaming together butter and sugar is almost always the first step in a cookie recipe. Start with softened butter and use a mixer and beat until the mixture is no longer grainy when rubbed between your fingertips. This usually takes about 5 minutes. This is an important step that adds air to the dough which will help it rise while baking.
- Measure your flour accurately by scooping it lightly into a dry measuring cup and then level it off with a knife. You should never dip the measuring cup into the flour or pack it against the cup with your hand or a spoon — you’ll end up with tough, dry cookies.
- For best results, line your pans with parchment paper or silicone baking mats. This helps with even baking as well as quick clean up!
- Adding eggs one at a time is another important step to make sure that they emulsify with the fats.
- Add the dry ingredients in small batches and mix just until incorporated into the wet ingredients. Do not overmix or the result will be one tough cookie!
