Ingredients You’ll Need
- 2 & 2/3 cups all-purpose flour: The foundation for your cookie bars. For gluten-free options, you can use a gluten-free baking blend.
- 1 teaspoon baking soda: This ingredient helps the bars rise and achieve that fluffy texture.
- 3/4 teaspoon salt: Elevates the sweetness by balancing flavors; kosher salt can work too.
- 1 cup unsalted butter browned and cooled down: Browning the butter adds a nutty flavor that really enhances the bars. Ensure it cools to room temperature to avoid cooking the eggs.
- 2/3 cup granulated sugar: For sweetness and structure, granulated sugar helps create that chewy base.
- 3/4 cup packed light brown sugar: The molasses content adds moisture and a deeper flavor. If you’re out, dark brown sugar can work as a substitute.
- 2 teaspoons vanilla extract: This aromatic ingredient imbues a warm, rich flavor. Pure vanilla extract is always the best choice!
- 2 large eggs at room temperature: Eggs help bind the mixture and provide moisture. Remember to let them sit out if they’re cold.
- 2/3 cup semi-sweet chocolate chips: They provide melty pockets of goodness throughout your bars.
- 1/2 cup pastel Easter M&M’s: Their colorful coating adds a fun touch. You can change this to seasonal M&M’s for variety.
- 1/2 cup crushed Cadbury mini eggs: These candy-coated treats bring a delightful crunch.
- 8-12 halved Cadbury crème-filled mini eggs (for topping): These glorious little eggs not only look beautiful on top but also offer a delicious creamy filling that complements the bars perfectly.
How to Make Cadbury Egg Cookie Bars

- Brown the Butter: In a medium saucepan over medium heat, melt 1 cup unsalted butter, stirring constantly. Watch as it foams, then sizzles, and starts to develop brown bits at the bottom. When the butter turns a golden brown and smells nutty, remove it from heat. Let it cool for 10-15 minutes.
- Mix Dry Ingredients: In a medium bowl, whisk together 2 & 2/3 cups all-purpose flour, 1 teaspoon baking soda, and 3/4 teaspoon salt. Set aside.
- Combine Wet Ingredients: In a large mixing bowl, combine the cooled browned butter (make sure it’s not too hot), 2/3 cup granulated sugar, 3/4 cup packed light brown sugar, and 2 teaspoons vanilla extract. Mix until smooth and glossy, then add 2 large eggs, mixing until fully combined.
- Incorporate Dry Ingredients: Gradually stir the dry mixture into the wet ingredients until just combined. There should be no dry pockets, but don’t overmix to keep them tender.
- Fold in the Fun Stuff: Gently fold in 2/3 cup semi-sweet chocolate chips, 1/2 cup pastel Easter M&M’s, and 1/2 cup crushed Cadbury mini eggs. Ensure they’re evenly distributed. Cover the bowl with plastic wrap and chill the dough in the fridge for 30-60 minutes. This step is crucial for developing flavor and preventing spreading.
- Preheat the Oven: While the dough chills, preheat your oven to 350°F (175°C). Prepare a 13.8×10-inch jelly roll pan by spraying it or lining it with parchment paper—the perfect non-stick layer.
- Spread the Dough: After chilling, spread the cookie dough evenly into the prepared pan. Feel free to reserve a few M&M’s and chocolate chips to press on top for extra flair!
- Bake the Bars: Pop them in the oven and bake for 18-22 minutes or until the edges are golden brown, and the center looks just set. Be careful not to overbake; they should remain soft in the middle!
- Add Toppings: Once baked, gently press the halved crème-filled Cadbury eggs on top of the still-hot bars. Their heat will help them adhere without melting completely. Allow the bars to cool completely before cutting.
Storing & Reheating
Store your Cadbury Egg Cookie Bars in an airtight container at room temperature for up to 3 days. For longer-lasting freshness, refrigerate them in a sealed container for up to a week. You can also freeze these delectable bars for up to 3 months. Just wrap them tightly in plastic wrap or foil and place them in a freezer bag for added protection. To refresh their taste and texture, reheat them in the microwave for about 15-20 seconds or until just warm.
Chef’s Helpful Tips
- Always cool the browned butter to prevent scrambling the eggs when combined.
- If using different types of chocolate chips, adjust the sweetness to your taste.
- To ensure even baking, use a light-colored pan to avoid over-browning.
- Feel free to mix in other candies or nuts based on your preferences—there’s plenty of room for creativity.
- Consider making the dough a day in advance. It chills beautifully, and you can simply bake fresh bars whenever you’re ready to indulge!
Cadbury Egg Cookie Bars not only promise a delightful blend of flavors and textures but also deliver an irresistible sweetness that feels both nostalgic and brand new. The combination of chocolate, M&M’s, and Cadbury eggs offers a great reason to celebrate with friends and family. Don’t hesitate to get creative and customize it to your liking!

Recipe FAQs
Can I use salted butter instead of unsalted?
Absolutely, you can use salted butter! If you go this route, just omit the additional salt in the recipe. The slight difference might add a nice flavor depth!
How do I know when the bars are fully baked?
Look for golden-brown edges and a center that seems just set—if it still looks slightly jiggly, it’s time to take them out. The bars will continue to firm up as they cool.
What can I substitute for Cadbury mini eggs?
If you can’t find Cadbury mini eggs, consider using other chocolate-covered candies, such as Reese’s Pieces or even chocolate chips for a simpler option.
Can I make these cookie bars ahead of time?
Yes! These cookie bars store well. Prepare them in advance and simply reheat before serving for that fresh-out-of-the-oven vibe, or enjoy them chilled for a refreshing treat!
