I thought I had written a blog post on these already -- I had definitely talked about them enough on facebook, but alas, there is no post here.
So, without much ado, but definitely much belated, here are these delicious (and easy!!) Peanut Butter Monster Cookie Bars!
Peanut Butter Monster Cookie Bars
From Averie Cooks
1/2 cup (1 stick) unsalted butter, melted
1 large egg
1 Tbsp vanilla extract
1 cup packed light brown sugar
1/2 cup (heaping) creamy peanut butter (the original recipe says to skip homemade or natural since they're too runny, but I used Skippy natural and it worked just fine)
1 cup flour
1 cup peanut butter M&Ms, plus a few extra for the top
3/4 cup semi-sweet chocolate chips, chunks, or a combination (I used a mixture)
1/2 cup peanut butter chips
1/3 cup toffee bits
Preheat the oven to 350F.
Line an 8x8" pan with foil.
Spray foil-lined pan with cooking spray.
In a large, microwave-safe bowl, melt the butter.
I did mine on 30 second intervals, to make sure it didn't get too hot.
Let cool for a few minutes, so that you don't scramble the eggs when you add them.
Add the egg, brown sugar, and vanilla.
Whisk until smooth.
Add the peanut butter, and with a whisk, incorporate until smooth.
Add the flour and stir until just combined, being sure not to overmix.
Add the add-ins (M&Ms, chips and chunks, and toffee bits).
Fold until incorporated.
Pour the batter into the pan.
With a spatula, smooth the top to make it flat.
Place a few of the peanut butter M&Ms on top, since it'll make them look extra pretty :)
Bake for about 24 minutes, or until the top is set.
Inserting a toothpick in the center is a good way to check -- it should come out clean or with a few moist crumbs. If there is batter, they are undercooked and need to bake longer.
Allow them to cool in the pan for at least a half hour, before cutting them.
