Ingredient Notes

Creating the perfect Brown Butter Cadbury Egg Skillet Cookie starts with understanding the role of each ingredient. While simple, the quality and preparation of these components are key to that irresistible chewy, gooey, and nutty flavor profile.

Unsalted Butter: This is the star of the show, obviously! We’re browning it, which transforms its flavor from simple dairy to a complex, nutty, caramel-like essence. Using unsalted butter allows us to control the overall saltiness of the cookie. Don’t be afraid to let it get deeply golden brown – that’s where all the magic happens!
Granulated Sugar & Brown Sugar: The combination here is strategic. Granulated sugar contributes to a slightly crisp edge and helps the cookie spread, while brown sugar (especially dark brown sugar) adds moisture, chewiness, and a deeper molasses-like flavor that complements the brown butter beautifully. Don’t swap them out for just one type if you want that perfect texture.
Large Egg & Egg Yolk: The whole egg provides structure and moisture, while the extra egg yolk adds richness, chewiness, and helps keep the cookie super tender. Make sure your eggs are at room temperature for better emulsion with the butter and sugars, leading to a smoother, more uniform dough.
Vanilla Extract: Use a good quality pure vanilla extract here. Its warmth and sweetness enhance all the other flavors, especially the brown butter and chocolate. Don’t skimp on the vanilla!
All-Purpose Flour: Standard all-purpose flour works perfectly for this skillet cookie. Make sure to measure it correctly, either by weight (my preferred method for accuracy) or by lightly spooning it into your measuring cup and leveling it off. Too much flour can make your cookie dry and dense.
Baking Soda & Salt: Baking soda helps the cookie rise and spread slightly, contributing to its chewy texture. Salt, often overlooked, is crucial for balancing the sweetness and intensifying all the flavors, especially the rich brown butter and chocolate. I always use fine sea salt in my baking.
Cadbury Mini Eggs: Ah, the seasonal stars! These provide that iconic crunch, creamy milk chocolate, and vibrant pop of color. I prefer using the mini eggs and roughly chopping them before adding to the dough. This ensures you get a piece of chocolate and candy shell in almost every bite.

Substitution Tip: If Cadbury Eggs aren’t in season or available, feel free to substitute with an equal amount of good quality milk chocolate chunks, chocolate chips (milk, dark, or a mix), or even other festive candies like M&M’s, chopped Snickers, or Reese’s Pieces. The core recipe is robust enough to handle various mix-ins.

Step-by-Step Instructions

Let’s get baking! This Brown Butter Cadbury Egg Skillet Cookie comes together with a few straightforward steps, but paying attention to the details will ensure a spectacular result.

Brown the Butter: In a light-colored saucepan or skillet (this helps you see the color change), melt the unsalted butter over medium heat. It will foam, then bubble, and eventually, the milk solids at the bottom will start to turn golden brown and smell nutty. Continuously whisk to prevent scorching. Once you see rich, amber-colored specs at the bottom and smell that irresistible nutty aroma, immediately remove it from the heat and pour it into a large, heat-proof mixing bowl. Let it cool for about 10-15 minutes until it’s no longer sizzling hot but still liquid. This cooling step is crucial to prevent scrambling your eggs later.
Combine Sugars and Butter: To your slightly cooled brown butter, add both the granulated sugar and brown sugar. Whisk them vigorously until well combined and the mixture looks smooth and glossy. The sugars will start to dissolve a bit into the warm butter.
Add Eggs and Vanilla: Now, add the large egg, the extra egg yolk, and the vanilla extract to the butter-sugar mixture. Whisk really well for about 1 to 2 minutes until the mixture is light in color, thick, and looks emulsified. This aeration step adds lightness to the cookie.
Whisk Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt until they are thoroughly combined. This ensures even distribution of your leavening agent and salt.
Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing with a wooden spoon or spatula until just combined. Be careful not to overmix! Overmixing develops the gluten in the flour too much, which can lead to a tough, dry cookie. Stop mixing as soon as you no longer see streaks of dry flour.
Fold in Cadbury Eggs: Gently fold in your chopped Cadbury Mini Eggs (or your chosen substitution) until they are evenly distributed throughout the dough. Reserve a few extra chopped eggs to press onto the top of the cookie before baking for a pretty finish.
Prepare Skillet & Bake: Lightly grease a 9-inch cast iron skillet with butter or a non-stick spray. Press the cookie dough evenly into the bottom of the prepared skillet. Press the reserved Cadbury Eggs onto the top. Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the edges are golden brown and set, and the center still looks slightly soft and gooey. Remember, it will continue to cook slightly from the residual heat of the skillet after it comes out of the oven.
Cool & Serve: Remove the skillet from the oven and let the cookie cool in the skillet on a wire rack for at least 15-20 minutes before serving. This allows it to set up properly. Serve warm, directly from the skillet, with a spoon for ultimate gooey indulgence!

Tips & Suggestions

To ensure your Brown Butter Cadbury Egg Skillet Cookie is absolutely perfect, here are a few extra tips and suggestions I’ve picked up along the way:

Don’t Rush the Brown Butter: This is truly the foundation of the flavor. Take your time, keep the heat at medium, and stir frequently. Getting it deeply amber with nutty bits at the bottom is crucial for that signature taste. Don’t let it burn, but definitely don’t under-brown it either!
Embrace the Gooey Center: A skillet cookie is meant to be a little gooey in the middle. The beauty of baking it in a cast iron skillet is that the residual heat continues to cook the center even after you pull it from the oven. If you prefer a firmer cookie, bake it for an extra 2-3 minutes, but keep in mind it might lose some of its signature chewiness.
Room Temperature Eggs: I mentioned it in the ingredients, but it’s worth repeating. Room temperature eggs emulsify much better with the butter and sugar, leading to a smoother, more uniform dough and ultimately a better-textured cookie.
To Chill or Not to Chill?: While many cookie doughs benefit from chilling, this skillet cookie dough is designed to be baked immediately. No need to chill, which makes it perfect for a spontaneous treat!
Serving Suggestions: This skillet cookie is an experience. Serve it warm, right out of the skillet, with a generous scoop (or two!) of vanilla bean ice cream. A drizzle of chocolate sauce, a dollop of fresh whipped cream, or a sprinkle of flaky sea salt (to enhance the flavors even more) would also be fantastic additions. Everyone can dig in with their own spoon!
Customization Beyond Cadbury Eggs: While Cadbury Eggs are festive and delicious, feel free to get creative! Mix in toasted pecans or walnuts for extra crunch and nuttiness, add a handful of white chocolate chips, or even a different type of chocolate bar chopped into chunks. The brown butter base is incredibly versatile.
Using the Right Skillet: A 9-inch cast iron skillet is ideal for this recipe. If you use a larger skillet, the cookie will be thinner and bake faster, so adjust your baking time. A smaller skillet will yield a thicker cookie that needs more time.

Storage

While this Brown Butter Cadbury Egg Skillet Cookie is best enjoyed warm and fresh from the oven, especially with ice cream, sometimes you might have leftovers. Here’s how to store it to keep it delicious:

At Room Temperature: Once the skillet cookie has completely cooled in the skillet (which can take a while due to the cast iron), you can transfer individual slices to an airtight container. It will stay fresh at room temperature for up to 3-4 days. For best quality, I recommend transferring it out of the skillet after cooling to avoid any metallic flavors developing over time, especially if storing for more than a day.
In the Refrigerator: If you live in a warm climate or prefer your desserts chilled, you can store the cookie slices in an airtight container in the refrigerator for up to a week.
Freezing for Longer Storage: This skillet cookie freezes beautifully! Once completely cooled, you can wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag or airtight container. It will keep well in the freezer for up to 2-3 months. You can also freeze the entire cooled cookie if you prefer, wrapped tightly in several layers of plastic wrap and then foil.
Reheating:
- From Room Temperature/Refrigerator: The easiest way to bring back that warm, gooey goodness is to pop a slice into the microwave for 15-30 seconds, or until warmed through. Alternatively, you can reheat slices in a preheated oven at 300°F (150°C) for about 5-10 minutes.
- From Frozen: For frozen slices, you can microwave them for 45-90 seconds, checking periodically. For a crispier edge, place frozen slices directly into a preheated oven at 325°F (160°C) for 15-20 minutes, or until warmed through. If reheating the whole frozen cookie, remove all wrapping and place it back in the skillet (or on a baking sheet) in an oven preheated to 300°F (150°C) for 20-30 minutes, or until heated through.
