Cadbury Egg Chocolate Brownies

There's something about the moment when you crack open a fresh box of Cadbury mini eggs that makes you feel like a kid again, even if you're standing in your kitchen at midnight with flour in your hair. I stumbled onto these brownies by accident one Easter, staring at a half-empty bag of mini eggs and thinking, why not throw them into something warm and chocolatey? The result was so ridiculously good that I've made them dozens of times since, each batch a little ritual of chocolate indulgence wrapped up in nostalgia.

I brought these to a work potluck once and watched someone take a second bite and just close their eyes like they were processing a spiritual experience. That's when I knew I'd stumbled onto something special, something that transforms a simple brownie into a proper celebration.

Ingredients

• Dark chocolate, 200 g: This is the backbone, so don't skimp on quality—a good 70% cocoa content gives you depth without bitterness.
• Unsalted butter, 120 g for base: Keeps the brownies fudgy and lets the chocolate shine without competing flavors.
• Granulated sugar, 200 g: The main sweetener that helps create those chewy edges and fudgy center.
• Light brown sugar, 100 g: This adds moisture and a subtle molasses note that deepens the chocolate flavor.
• Eggs, 3 large: They bind everything together and create that signature dense, fudgy texture when you don't overmix.
• Vanilla extract, 1 tsp: A tiny bit that amplifies the chocolate without making itself known.
• All-purpose flour, 120 g: Measure by weight if you can, otherwise spoon and level to avoid a dry brownie.
• Unsweetened cocoa powder, 30 g: The second hit of chocolate that makes these brownies sing.
• Salt, ½ tsp: This small amount balances sweetness and makes the chocolate taste more intense.
• Cadbury mini eggs for base, 100 g: Halve or crush them lightly so they distribute throughout without sinking.
• Unsalted butter for topping, 50 g melted: Binds the crumble mixture into those gorgeous golden clusters.
• All-purpose flour for topping, 75 g: Creates the crumbly texture that contrasts beautifully with soft brownie.
• Light brown sugar for topping, 25 g: Sweetens the crumble without overpowering the chocolate.
• Cocoa powder for topping, 2 tbsp: Another layer of chocolate flavor right on top.
• Dark or milk chocolate for topping, 50 g: Chopped fine so it melts slightly in the oven and adds richness.
• Cadbury mini eggs for topping, 50 g: Crushed roughly for visual appeal and those little bursts of sweetness in every bite.

Instructions

Prep your pan and oven:

Preheat to 180°C (350°F) and line a 23 cm square pan with parchment paper, leaving some overhang so you can lift the whole thing out later. This is the difference between brownies you can share and brownies that crumble into sadness.

Melt chocolate and butter together:

Use a heatproof bowl over simmering water or the microwave in 30-second bursts, stirring between each one—this keeps everything smooth and prevents seizing. Let it cool for a minute before moving on.

Build the base batter:

Whisk in both sugars until they're combined, then add eggs one at a time, whisking after each so they incorporate properly. This is where your brownie gets its structure, so don't rush it.

Add the dry ingredients:

Sift in flour, cocoa powder, and salt, then fold gently until just combined—stop as soon as you don't see streaks of dry flour. Overmixing develops gluten and makes brownies cake-like, which is the opposite of what we want.

Fold in the mini eggs:

Add the halved or crushed Cadbury eggs and spread everything into your prepared pan, smoothing it out gently. The eggs should be somewhat evenly distributed but don't stress about perfection.

Make the crumble topping:

Mix melted butter, flour, brown sugar, and cocoa powder until you get sandy, crumbly bits, then stir in chopped chocolate and crushed mini eggs. This should feel loose and chunky, not wet.

Top and bake:

Sprinkle the crumble mixture evenly over the batter and bake for 28-32 minutes until the edges are set but the center still jiggles slightly. A skewer inserted in the middle should come out with a few moist crumbs, not wet batter and not clean.

Cool completely:

This is the hardest part—let them sit in the pan until they're completely cool before lifting out and cutting. Warm brownies are delicious but they'll fall apart; cold ones cut cleanly and taste even better.

There's a moment when you pull these out of the oven and the smell hits you that feels like pure magic, like something bigger than just dessert. These brownies stopped being about food and became about the excuse to gather people around something warm and chocolatey.

The Crumble Topping Magic

The crumble is honestly what elevates these from good brownies to the kind you dream about. It adds this textural element that keeps you coming back for more, and those little pockets of chocolate and mini eggs are like finding treasure with every bite.

Storage and Serving Ideas

Store these in an airtight container for up to five days, though they rarely last that long in my house. They're perfect slightly warm with vanilla ice cream, or eaten straight from the fridge when you need a 3 p.m. chocolate boost.

Customization and Substitutions

These brownies are forgiving enough to adapt to whatever you have on hand, which is part of why I keep making them. Swap the mini eggs for crushed Maltesers, use milk chocolate instead of dark, or even add a pinch of instant espresso powder to deepen the chocolate flavor.

• If you can't find Cadbury mini eggs, any chocolate-covered candy works beautifully, or just use extra chopped chocolate.
• For a nuttier version, fold some toasted hazelnuts or almonds into the batter before baking.
• Make these dairy-free by using quality dairy-free chocolate and butter—the texture stays fudgy and delicious.
