Ingredients You’ll Need
- 2 & 2/3 cups all-purpose flour: Provides the foundation of the cookie bars and gives them structure.
- 1 teaspoon baking soda: This leavening agent ensures a lighter texture, preventing heaviness.
- 3/4 teaspoon salt: Balances sweetness and enhances flavor.
- 1 cup unsalted butter, browned and cooled to room temperature: Browning the butter adds a nutty flavor that enhances the cookies.
- 2/3 cup granulated sugar: Sweetness for the cookie base.
- 3/4 cup packed light brown sugar: Adds moisture and a subtle caramel flavor.
- 2 teaspoons vanilla extract: For that classic cookie aroma and flavor.
- 2 large eggs at room temperature: Binds the ingredients together; room temperature helps them incorporate better.
- 2/3 cup semi-sweet chocolate chips: For added richness and chocolatey bites.
- 1/2 cup pastel Easter M&M’s: For color, a fun look, and extra sweetness.
- 1/2 cup crushed Cadbury mini eggs: Tries to capture that signature Cadbury flavor and fun crunch.
- 8-12 Cadbury crème-filled mini eggs, halved (for topping): Adds an eye-catching finish and a burst of flavor right on top.
How to Make Cadbury Egg Cookie Bars

- Brown the Butter: In a medium saucepan over medium heat, melt 1 cup of unsalted butter, stirring constantly. It will foam, sizzle, and develop brown bits. When it smells nutty and is golden brown, remove it from heat and let it cool for about 10-15 minutes.
- Mix Dry Ingredients: In a medium bowl, whisk together 2 & 2/3 cups of all-purpose flour, 1 teaspoon of baking soda, and 3/4 teaspoon of salt. Set this mixture aside.
- Prepare Wet Ingredients: In a large mixing bowl, combine the cooled browned butter (ensuring it’s not too hot) with 2/3 cup of granulated sugar, 3/4 cup of packed light brown sugar, and 2 teaspoons of vanilla extract. Mix until smooth and glossy. Add in 2 large eggs, one at a time, mixing until just combined.
- Combine Mixtures: Gradually stir the dry ingredients into the wet mixture, mixing until just combined.
- Fold in Extras: Gently fold in 2/3 cup of semi-sweet chocolate chips, 1/2 cup of pastel Easter M&M’s, and 1/2 cup of crushed Cadbury mini eggs. Cover the bowl and chill the dough in the fridge for 30-60 minutes; this helps the flavors meld and prevents spreading.
- Preheat Oven & Prepare Pan: While the cookie dough chills, preheat your oven to 350°F. Spray or line a 13.8×10 jelly roll pan with parchment paper.
- Spread Dough: Once chilled, spread the dough evenly into the prepared pan. For a decorative touch, you can reserve a few M&M’s and chocolate chips to press on top.
- Bake: Bake for 18–22 minutes, or until the edges are golden brown and the center looks just set. Don’t overbake to ensure they stay soft!
- Add Toppings: Immediately after removing the bars from the oven, gently press the halved crème-filled Cadbury eggs on top while they’re still warm. They’ll adhere but won’t melt completely. Allow the bars to cool completely before cutting.
Storing & Reheating
Store your Cadbury Egg Cookie Bars at room temperature in an airtight container for about 3-4 days, or in the refrigerator for up to a week. If you’re looking to keep them longer, freeze the bars in an airtight container, separating layers with parchment paper, for up to 3 months. When ready to enjoy, simply reheat them in a microwave for about 10-15 seconds to refresh the melty chocolate vibe. Keep in mind that the texture may slightly change after freezing, but they will still be delightful!
Chef’s Helpful Tips
- Don’t rush browning the butter: The nutty flavor is essential, so take your time.
- Room temperature eggs are crucial: They blend better and create a smoother batter.
- Avoid overmixing: Stir just until combined to prevent tough cookie bars.
- Chilling the dough is a must: It helps control spread and enhances flavors.
- Watch the baking time: Check around 18 minutes to pull them out even if they seem not fully baked; they’ll continue to firm up as they cool.
Cadbury Egg Cookie Bars offer the perfect sweet treat that balances nostalgia and indulgence. With their vibrant colors and comforting flavors, they make a fantastic addition to any celebration or simply to satisfy a sweet tooth. I encourage you to try this recipe, experimenting with maybe adding nuts or different candies for unique creations of your own. Enjoy every bite!

Recipe FAQs
Can I use different types of chocolate?
Absolutely! Feel free to swap semi-sweet chocolate chips with milk or dark chocolate chips based on your preference. Or, mix them for a varied chocolate experience.
Can I make these cookie bars gluten-free?
Yes! You can replace the all-purpose flour with a gluten-free flour blend. Just ensure that the blend you use has xanthan gum or adds some to help mimic the texture of regular flour.
How do I know when my cookie bars are done?
Look for golden brown edges and a center that looks set but slightly soft. A toothpick inserted in the middle should come out with moist crumbs, not wet batter.
Can I use whole Cadbury mini eggs instead of halved ones for topping?
While you can, halving them allows the creamy centers to ooze slightly on top and enhances the overall visual appeal and flavor experience right as they bake.
