Cadbury Mini Egg Blondies are a delightful treat that combines the rich, buttery flavor of classic blondies with the fun crunch of colorful Cadbury Mini Eggs. These little bars have a soft and chewy texture that melts in your mouth and are dotted with the vibrant candy eggs that add a yummy burst of chocolate and a bit of festive flair.
I love making these blondies around springtime or Easter because they feel extra special with those little pastel eggs baked right in. The contrast between the smooth, sweet blondie base and the crisp candy shells makes every bite feel like a little celebration. I usually sneak a few Mini Eggs on top just before baking for an extra pretty finish and because, honestly, more candy is always better in my book.
These blondies are perfect for sharing with friends or family, especially for dessert after a cozy meal or as a sweet snack during a movie night. I find they’re great served warm with a scoop of vanilla ice cream, but they also travel well if you want to bring some happiness to a picnic or a potluck. Whenever I make these, they disappear fast—think of them as a sweet little gift everyone’s happy to get their hands on!
Key Ingredients & Substitutions
Butter: Melted unsalted butter gives the blondies their rich, moist texture. You can swap it with salted butter, just reduce or skip adding extra salt in the recipe to keep balance.
Sugars: Using both brown and granulated sugar creates moistness and a slight crunch. If you want less sweetness, reduce granulated sugar a bit or try coconut sugar as a natural alternative.
Cadbury Mini Eggs: These add fun color and melty chocolate bits inside the blondies. If unavailable, you can use chopped chocolate eggs or even chocolate chips mixed with chopped candy shells for a similar effect.
Flour & Leavening: All-purpose flour works well to give structure. Baking powder helps the blondies rise lightly, keeping them soft but set. Don’t skip or replace it with baking soda—they work differently here.
How Do You Avoid Overmixing the Batter for Perfect Blondies?
Mixing is key to tender blondies. Overmixing the flour with wet ingredients can make them dense and tough, so it’s best to fold just until you see no more flour.
- Start by sifting flour, baking powder, and salt together for even distribution.
- Add dry ingredients gradually to the wet mix, folding gently with a spatula.
- Stop mixing as soon as the batter looks combined, even if some streaks remain.
- Fold in the chopped Mini Eggs carefully so the chocolate pieces stay intact and don’t melt too much before baking.

Equipment You’ll Need
- 9×9 inch (23×23 cm) square baking pan – I like it because it gives the blondies their perfect thickness and shape.
- Parchment paper – makes lifting out the blondies easy without sticking.
- Large mixing bowl – for combining the wet ingredients smoothly.
- Whisk or spatula – helps you mix the ingredients evenly without overworking the batter.
- Measuring cups and spoons – for accurate measurement, ensuring consistent results.
- Small bowl – for sifting the dry ingredients so they mix well with the wet.
Flavor Variations & Add-Ins
- Swap Cadbury Mini Eggs with milk or dark chocolate chips for a simpler chocolate fix.
- Add chopped nuts, like walnuts or pecans, for extra crunch and flavor.
- Mix in a handful of shredded coconut for a tropical touch.
- Sprinkle a pinch of sea salt on top before baking to enhance the chocolate flavor and add a salty contrast.

How Much Time Will You Need?
This recipe takes about 10 minutes of prep time and 25-30 minutes to bake. Then, allow the blondies to cool completely before cutting and serving—expect around an hour total, including cooling.
Step-by-Step Instructions:
1. Prepare to Bake:
Preheat your oven to 350°F (175°C). Line a 9×9 inch (23×23 cm) square baking pan with parchment paper, leaving some overhang on the sides so you can easily lift the blondies out later.
2. Mix the Wet Ingredients:
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
3. Combine Dry Ingredients and Mix Gently:
In a separate bowl, sift the flour, baking powder, and salt. Gradually fold the dry mix into the wet ingredients, stirring until just combined. Try not to overmix to keep your blondies tender.
4. Add the Chocolatey Touch:
Gently fold in the chopped Cadbury Mini Eggs, saving a handful to sprinkle on top of the batter once it’s in the pan.
5. Bake and Cool:
Pour the batter into your prepared pan, spreading it out evenly. Sprinkle the reserved Mini Eggs on top, and optionally add a sprinkle of granulated sugar for a sweet crunch. Bake for 25-30 minutes, until the edges look golden and a toothpick inserted in the center comes out with a few moist crumbs.
6. Finish and Serve:
Let the blondies cool completely in the pan on a wire rack. Use the parchment paper overhang to lift the blondies out, then cut into squares. Enjoy immediately, or store leftovers in an airtight container at room temperature.
Can I Use Frozen Cadbury Mini Eggs?
While you can, it’s best to use them at room temperature so they chop cleanly without crumbling too much. If frozen, let them thaw fully before chopping and adding to the batter.
Can I Make These Blondies Ahead of Time?
Absolutely! You can bake them a day in advance and store in an airtight container at room temperature. They actually taste even better after a day as the flavors meld together.
How Should I Store Leftovers?
Keep any leftover blondies in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze cut pieces wrapped tightly in plastic wrap and foil for up to 1 month.
Can I Substitute the Flour?
All-purpose flour works best here for the right texture. You could try a gluten-free blend, but results may vary — the blondies might be a little denser or crumblier. Always sift your flour for best results!
