Reese's Stuffed Monster Cookie Cups

WE'VE MOVED! Now redirecting you to our new page.

Some recipes are the ripe, succulent fruits of pure inspiration. (Apple Pie Babycakes) Some recipes are the product of craving (PB&J Pretzel Swirl Brownies) or commission (Pumpkin Whoopie Pies). Some recipes are made for an occasion. (Chocolate Pumpkin Cheesecake Layer Cake) Some recipes are what happens when a "What if...?" actually reaches fruition. (Childhood Sandwich Supreme Cupcakes) And some recipes happen because you have surplus ingredients lying around leftover from previous projects that you're sick of looking at in the pantry and just want to get rid of. Irritation is the mother of invention, as they say. (Wait. That's not what they say? Oh. Well. Never mind.)

These fall into the final category.

I've had a half-used bag of mini Reese's taking up space in my small makeshift dorm pantry (really just a glorified cabinet in what's supposed to be my closet space) since about September. It was time to get rid of those suckers.

I've also been craving monster cookies lately. (Oat-y, peanut buttery, M&M and chocolatey goodness. What's not to crave??) So I decided to combine these two agendas. I guess that means these cookies really fall into two categories of invention: craving AND I-just-want-to-stop-looking-at-these-dang-Reese's-already.

I decided to solve my surplus Reese's problem by hiding them inside monster-sized monster cookie cups. Kind of like the baking equivalent of cleaning your room by shoving all your stuff under the bed and hoping your mom wouldn't notice. But I'm sure you never did that, because you were the model of childhood obedience. Right? Right. ;) So kind of just like that...only better. Because Reese's certainly make for a better surprise when your secret is (inevitably) discovered. I'm pretty sure this one will earn you hugs, not scolding.

I used Sally's soft-baked monster cookie recipe as my base. It turned out well enough, but I would have liked more oats to give the cookies extra substance and general oomph factor.

The Reese's in the middle, though...now that (to toot my own horn) was inspired. That nugget of peanut buttery/chocolatey goodness made the cookie. Sinking your teeth into a mouthful of peanut butter, oats, mini M&M's, and Reese's is a one-way fast route to your happy place. Guaranteed.

I'll post Sally's recipe below, but if you have your own favorite monster cookie recipe already, I would recommend just using that instead. All you need to do to turn them into Reese's Stuffed Monster Cookie Cups is to bake them in a cupcake pan with a Reese's hidden between two layers of cookie dough. And bake them a little longer than you normally would. (Not too long, though - keep an eye on them! Start at just a couple minutes over the usual baking time.)

Easy peasy!

Whatever your reason for making this recipe, I'm sure it's a good one. And if you don't already have a reason, here's a fool-proof one: Just because.

Reese's Stuffed Monster Cookie Cups
Adapted from Sally's Baking Addiction

1/2 cup salted butter, softened to room temperature
1/2 cup light brown sugar
1/4 cup sugar
3/4 cup creamy peanut butter
1 large egg
1 teaspoon vanilla extract
1/2 teaspoon baking soda
1 and 1/4 cups all purpose flour
1/2 cup quick oats
3/4 cup mini M&Ms
12 mini Reese's cups

Preheat oven to 350F degrees. Grease a cupcake pan.

In a large bowl, using a hand-held mixer or stand mixer with paddle attachment, cream the butter and sugars together on medium speed, about 3 minutes. Mix in the peanut butter, egg, and vanilla (in that order). Scrape down the sides of the bowl as needed. Slowly mix in the baking soda and flour. Do not overmix. Fold in the quick oats, M&Ms, and chocolate chips. If the dough is very soft and unmanageable by hand, chill the dough for 30 minutes before rolling.


Line the bottom of the cupcake cups with cookie dough. Place a Reese's inside. Cover with enough dough to conceal Reese's. Bake for 10-14 minutes, or until just browning. (Keep an eye on them!) Allow cookies to cool completely before removing from cupcake pan. Enjoy!
