Giant One-Pan Skillet Cookie (With Loads of M&Ms!)

Hi Bold Bakers!

If you’re wondering what this recipe is like — I urge you to get right up to your screen and check out the photos. It’s a giant gooey cookie that’s still crispy on the outside and had loads of M&Ms throughout, and it tastes as awesome as it looks. Did I mention that when you mix it all together, you do it right in the skillet? It couldn’t be easier, and it’s essentially a Homemade Pizookie!

And yet… I decided to make this recipe because Gina Brazão, the new co-host of our baking podcast Knead to Know, said it’s been a dream of hers to make one, but she kept coming up short in different ways (I suspect her oven’s temperature is secretly broken). So, I solved all of her hurdles through testing and showed her how she can be successful with it right at home. Check out the video below for the how-to and see Gina finally make her dream dessert!

What Is A Skillet Cookie?

A skillet cookie is a giant cookie made right in an oven-safe skillet — I use my cast iron pan for this. No, you don’t scoop out the cookie dough into balls and bake them on a sheet, you keep the dough right in the skillet and portion it out later with a big dollop of vanilla ice cream. This cookie has loads of flavor because of the melted butter getting a little brown.

Skillet Cookies vs. Regular Cookies

When you make a skillet cookie, you’re looking for one thing: gooey. When you make individual cookies, you can still find yourself with a gooey dessert, but trust me, it’s less so than you get with a skillet cookie. Think of it as a deep-dish cookie instead of your usual hand-held cookies made by the dozen.

Skillets

As I mentioned above, you want to use an oven-safe skillet. Make sure you don’t use one that has a handle that can melt, and double-check for what temperature your skillet is oven-rated. At 350 degrees, this recipe doesn’t bake so hot that you’ll have a hard time finding a skillet to work with. And if you don’t have a cast iron skillet yet, this is your sign to get one.

Toppings & Mix-Ins

It’s no secret that my favorite candy is M&Ms, though I don’t eat them often because if they’re in the house, I will eat them. This recipe is an exception, though, but you can make this recipe as a chocolate chip, chocolate chunk, or even peanut butter cup cookie if you’d like. I’m not going to stop you!

What You Need To Make The Best Skillet Cookie

• An oven-safe skillet
• Measuring cups and spoons
• A bowl to combine the dry ingredients

Essential Steps For Making My Skillet Cookie

There wasn’t a lot of trial and error in this recipe — but I did find that the best path to flavor has three things: the melted butter getting a little brown, plenty of vanilla, and plenty of salt (yes, salt will enhance sweet desserts!). Don’t skip these.

Also, make sure your eggs are at room temperature. This helps with blending the ingredients.

When it comes to texture, the ideal result here is a cookie that’s crispy on the outside, but still gooey in the middle. Don’t be afraid — it is not undercooked if it’s gooey or a bit doughie inside. Follow the time in the recipe for the right bake time & temperature, and watch my how-to video below to get a complete look at how this bad boy should look when you pull it out of the oven.

Gemma’s Pro Chef Tips For Making Skillet Cookies

• Make the dough in advance and keep it in the fridge for up to 2 days. Bake off fresh.
• Replace the M&M’s with chocolate chips, or white chocolate chips & toasted pecans.
• Don’t be shy with the vanilla or salt!
• Brown the butter a little to give your cookie a nutty, deeper flavor.
• Make sure your eggs are room temperature and not cold from the fridge. This is better for them to blend into the warm ingredients.
• Take care not to overtake so your cookie is gooey and soft in the middle.
