No flour monster cookie bars are the perfect back-to-school snack! They freeze really well and who can resist these bars loaded with oatmeal, peanut butter, chocolate chips, and m&m’s?!
Are you ready for back-to-school? This is my first year sending a child to “real school”, like at an elementary school where he is there all day and rides the bus. I’m so nervous but yet so excited. I know he will love it.
With back-to-school comes the dreaded, “I’m starving mom!” the second they walk in the door. I remember doing that growing up, so I am sure my sweet little kindergartner will do the same thing. These no flour monster cookie bars are so delicious and perfect for an after school snack to fill their little bellies after a long day. The recipe makes an entire cookie sheet, so I always freeze some and pull them out when needed. I just put a couple in a Ziploc bag and freeze them that way. They only have to sit out for several minutes to thaw a bit or you could microwave for 20 seconds or so.
I mean, seriously!? WHO can resist that? I am a sucker for all things monster cookie. The combo of peanut butter, oats, and those cute mini rainbow m&m’s just can’t be beat.
I will note that this recipe calls for both quick oats and old-fashioned (regular) oats. You could use all quick, but I have found that using all quick oats results in a tough/dense cookie bar. Splitting the oats results in a soft and delicious cookie bar. Another tip is to use a pizza cutter to cut these into squares. I do that every time and it’s so easy!
1 cup packed brown sugar
1 cup granulated sugar
1/2 cup (1 stick) salted butter, softened
1 1/2 cups creamy peanut butter
3 large eggs
1 tablespoon vanilla extract
1 1/2 cups quick oats
3 cups old-fashioned oats
1 teaspoon baking soda
1-2 cups mini m&m’s
1 cup mini chocolate chips
Heat oven to 350 degrees. Prepare a cookie sheet by lining it with parchment paper, silpat liner, or spray with cooking spray.
In large bowl, or bowl of a stand mixer, combine brown sugar, granulated sugar, peanut butter, and butter.
Beat until pale in color and fluffy.
Add the eggs and vanilla extract. Blend together.
Add in the oats and baking soda. With a rubber spatula or wooden spoon, mix by hand until combined.
Add in the m&m’s and chocolate chips (reserve some for top of bars if wanted). Stir together well until combined.
Dump onto your parchment lined cookie sheet and spread out. This will take several minutes, but it can be done. Sprinkle the reserved m&m’s and chocolate chips on top (if wanted). Press down slightly into dough.
Bake for 17-20 minutes. The edges will be lightly browned and the middle will still look pale and underdone, but it will finish baking as it cools.
Let cool for at least an hour so the bars can firm up and come together. You do not want to over-bake these!
