Ingredients You’ll Need
- 2 & 2/3 cups all-purpose flour: Creates the perfect base for your cookie bars. Ensure you measure correctly for the right texture.
- 1 teaspoon baking soda: This leavening agent helps the bars rise and become fluffy.
- 3/4 teaspoon salt: Enhances the sweetness and balances the flavors.
- 1 cup unsalted butter, browned and cooled to room temperature: Browning the butter adds a rich, nutty flavor that’s irresistible.
- 2/3 cup granulated sugar: Provides sweetness and structure.
- 3/4 cup packed light brown sugar: For moisture and a hint of caramel flavor.
- 2 teaspoons vanilla extract: Adds warmth and depth to your cookie dough.
- 2 large eggs at room temperature: They help bind the ingredients together. Bring them to room temperature for better emulsification.
- 2/3 cup semi-sweet chocolate chips: Perfect for that classic chocolate chip flavor.
- 1/2 cup pastel Easter M&M’s: Bright, fun additions that add crunch and sweetness.
- 1/2 cup crushed Cadbury mini eggs: A must for that Cadbury flavor; these provide delightful bits of candy throughout.
- 8-12 halved Cadbury crème-filled mini eggs (for topping): Place these on the bars right out of the oven for an eye-catching finish.
How to Make Cadbury Egg Cookie Bars

- Brown the Butter: In a medium saucepan over medium heat, melt 1 cup unsalted butter. Stir constantly until it foams, then sizzles, and you see golden brown bits form at the bottom. This usually takes about 5-7 minutes. Allow it to 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 to combine. Set aside the dry mix.
- Combine Wet Ingredients: In a large mixing bowl, add the cooled browned butter, 2/3 cup granulated sugar, 3/4 cup packed light brown sugar, and 2 teaspoons vanilla extract. Mix until smooth and glossy. Then, add in 2 large eggs and blend until combined.
- Combine Wet & Dry Mixtures: Gradually stir the dry ingredients into the wet mixture until just combined. Be careful not to overmix!
- Add Fun Ingredients: Stir in 2/3 cup semi-sweet chocolate chips, 1/2 cup pastel Easter M&M’s, and 1/2 cup crushed Cadbury mini eggs. Gently fold to distribute everything evenly. Cover the bowl and chill the dough in the refrigerator for 30-60 minutes to firm up.
- Prepare the Baking Pan: While the dough chills, preheat your oven to 350°F (175°C) and spray or line a 13.8×10 jelly roll pan with parchment paper for easy removal.
- Spread the Dough: Once chilled, spread the cookie dough evenly into the prepared pan. Want a visual treat? Reserve a few M&M’s and chocolate chips to sprinkle on top.
- Bake Them: Bake in the preheated oven for 18–22 minutes, until the edges are golden brown. The center should look just set; don’t overbake! Keep an eye on them towards the end.
- Topping with Cadbury Eggs: As soon as the bars come out of the oven and are still hot, gently press the halved Cadbury crème-filled mini eggs on top. They’ll stick nicely without fully melting. Allow the bars to cool completely before cutting.
Storing & Reheating
Store any leftover Cadbury Egg Cookie Bars at room temperature in an airtight container for up to 3 days. If you want to keep them fresh longer, refrigerate for up to a week. For longer storage, freeze in an airtight container for up to 3 months. To enjoy again, simply thaw in the refrigerator and reheat in the oven at 350°F for about 5-10 minutes, or until warmed through. Note, the texture may change slightly after freezing, but a quick warmth refreshes the flavor!
Chef’s Helpful Tips
- Ensure your butter is cooled after browning; hot butter can cook the eggs, affecting the texture.
- Avoid overmixing after adding the dry ingredients to maintain softness.
- Use fresh Cadbury mini eggs for the best flavor and texture; stale ones won’t have that delicious crunch.
- You can easily make these bars ahead of time—perfect for Easter or holiday planning!
- Test doneness with a toothpick; it should come out with a few moist crumbs but not wet batter.
There’s something truly special about homemade desserts that brighten up any occasion. These heavenly Cadbury Egg Cookie Bars embody the very spirit of sharing sweetness and joy. Whether it’s springtime festivities or just an afternoon craving, these bars are sure to satisfy. Don’t hesitate to switch out ingredients or toppings to create your unique twist.

Recipe FAQs
Can I use different types of candy?
Absolutely! While this recipe features Cadbury mini eggs and pastel M&M’s, feel free to substitute with your favorite candies. Try using chocolate-covered pretzels or seasonal candies to switch things up!
How do I know when the cookie bars are done baking?
Now, the key to perfect cookie bars is not to overbake them. The edges should be golden brown, while the center may still look slightly underbaked. They will continue cooking after being removed from the oven, so keep an eye on them!
Can I make these cookie bars ahead of time?
Yes! You can prepare the dough a day in advance and refrigerate it until you’re ready to bake. Once baked, they can stay fresh at room temperature for a few days, making them great for planning ahead.
What if I don’t have a jelly roll pan?
If you don’t have a jelly roll pan, you can use a 9×13-inch baking dish instead. Just adjust the baking time slightly since thinner bars will cook faster! Be sure to check them a few minutes earlier. Enjoy your baking!
