I love how these brownies take the iconic Cadbury Egg and transform it into something entirely new. After tinkering with various ways to recreate that magical yellow-and-white filling, I discovered that the secret lies in getting the consistency just right - firm enough to create distinct layers but soft enough to mimic that gooey center we all love from the original eggs.
Last Easter, my brother (who hoards Cadbury Eggs every spring) ate three of these in one sitting. Sometimes the best recipes are the ones that riff on flavors we already love.
Essential Ingredients
- Dark Chocolate Brownie Mix: The deeper color creates better contrast with the filling
- Corn Syrup: Creates that signature gooey texture
- Powdered Sugar: For sweetness and body in the filling
- Yellow Food Coloring: For that iconic "yolk" layer
- Store-Bought Frosting: The shortcut that makes the topping so perfect

Creating Your Brownies
The Base Build
- Start with your brownie mix - follow those box directions exactly. The base needs to be perfectly cooked and cooled before adding those special layers:
The Filling Magic
- Beat your corn syrup, butter, vanilla, and powdered sugar until perfectly smooth. This mixture is the star of the show - just like in the eggs themselves:
Layer Love
- Split that filling, color half yellow, then create your layers. The chilling time between layers is crucial - don't rush this step!
The Frosting Trick
- Warming that store-bought frosting makes it pourable, creating that perfect smooth top layer:

Through countless Easter gatherings and spring celebrations, these brownies have become my signature holiday treat. They prove that sometimes the best recipes are the ones that combine nostalgic flavors with a fresh presentation.
