What Is a Brookie? 

A brookie is a unique dessert that is made with both brownie batter and cookie dough, usually chocolate chip. Typically, the dessert is made with a base of brownie batter, and cookie dough pieces are sprinkled on top. 

Then, it’s baked in the oven. The end result is an indulgent dessert that is moist and fudgy like a brownie on the bottom yet crisp and slightly crunchy on the top like a cookie! 

Originally created by Jovon English, brookies now exist in a wide variety of shapes, sizes, and flavors with endless options like brown butter brookies cookies, our sheet pan brookie recipe, and easy s’mores brookie bars

What’s In an M&M Skillet Brookie? 

  • Flour – Regular all-purpose flour forms the base of both the brownie batter and cookie dough. If needed, a 1:1 gluten-free all-purpose flour can be used instead. 
  • Sugar – Both granulated sugar and light brown sugar are used to sweeten the dessert while keeping it soft and moist. 
  • Large Eggs – One egg and one egg yolk are used in both the batter and the dough to provide structure and make the flavor extra rich.
  • Unsalted Butter – If salted butter is what you have on hand, just adjust the amount of extra salt included.  
  • Baking Soda – Make sure it’s fresh! Otherwise, your brookie skillet won’t rise. 
  • Sea Salt – Just a pinch helps the rest of the ingredients stand out. 
  • Vanilla Extract – Pure vanilla extract is crucial in baking to help add depth to the flavor. 
  • Chocolate Chips – Semi-sweet chocolate chips are folded into the cookie dough for a classic chocolate chip cookie recipe. Then, we add dark chocolate chips into the brownie batter for layers and layers of chocolatey goodness! 
  • Unsweetened Cocoa Powder – Forms the base of the brownies. 
  • Instant Coffee Powder – Technically optional, this helps enhance the chocolate in the brownie batter. If preferred, feel free to use decaf coffee powder instead. 
  • M&Ms – Sprinkled on top, these make your skillet brookie extra delicious. Use holiday-themed M&Ms to make this brookie skillet festive!

How to Make an Easy M&M Skillet Brookie

Because we’re technically making two recipes, this skillet brookie recipe takes a little effort. But don’t worry! It’s still easy and super fun. Here’s what to do: 

  1. Sift the Dry Ingredients. Sift the dry ingredients together in a large bowl, and set it aside. 
  2. Mix the Wet Ingredients. In a separate medium-sized bowl, cream the melted butter, brown sugar, and white sugar until smooth. Add the eggs one at a time, beating them until they’re well incorporated and the mixture is fluffy. Add the vanilla extract, and beat again. 
  3. Combine the Wet and Dry Ingredients. Add the dry ingredients to the bowl of wet ingredients, and stir just until smooth. Gently fold in the chocolate chips.

  2. Cream the Wet Ingredients. In a separate medium-sized bowl, cream the butter, brown sugar, and granulated sugar until smooth. Add the eggs one at a time, beating in between. Beat in the vanilla extract. 
  3. Combine the Wet and Dry Ingredients. Slowly add the dry ingredients to the bowl of wet ingredients, and stir to combine. Be careful not to overmix. Then, fold in the chocolate chips. 

Skillet Brookie

  1. Prepare. Preheat your oven, and grease a large skillet. 
  2. Layer the Ingredients. Add the cookie dough and brownie batter to the skillet in an alternating pattern, pressing it down gently. 
  3. Top. Sprinkle the M&Ms on top using as little or as much as you’d like. 
  4. Bake. Place your skillet brookie in the oven until the cookie dough is golden and a toothpick can be inserted into the center and comes out clean. It may seem a little underdone at first, but it will continue to set as it cools. So, be careful not to overbake!
  5. Enjoy! Let your brookie cool slightly, and enjoy while it’s still warm, preferably topped with a scoop of vanilla ice cream!

Common Questions About This M&M Skillet Brookie Recipe

Can I make this recipe ahead of time? 

Feel free to assemble the brookie skillet, cover it with plastic wrap, and store it in the fridge for a few hours before baking. For the best results, let it come to room temperature before baking. 

Can I add different ingredients? 

Absolutely! Feel free to mix and match whatever you like best. For instance, you could use a different cookie dough such as peanut butter cookie dough, monster cookie dough, or s’mores cookie dough. Or, swirl in caramel sauce, add chopped nuts, and swap out or add to the M&Ms with any other candy pieces such as Reese’s Pieces, KitKats, or toffee bits. 

How long does this recipe last? 

Leftovers can be transferred to an airtight container and stored at room temperature for up to one week or in the freezer for up to six months. To enjoy, allow your skillet brookie to thaw in the fridge overnight. Then, enjoy it cold, or pop it in the microwave for a few seconds to warm back up.
