Preheat your oven to 350 degrees and lightly grease the bottom of an 8×8 baking pan, then line it with parchment paper.
In a microwave safe bowl, melt the butter until soft and allow it to cool for a few minutes.
Add in the cocoa powder and sugar then whisk until combined.
Add the eggs, vanilla extract, and salt. Mix until the eggs are just incorporated.
Slowly add in the flour and baking powder, mixing until combined.
Fold in half the mini Cadbury eggs.
Pour the brownie batter into the pan you prepared earlier. Spread it out gently and evenly using a spatula.
Sprinkle the other half of the chopped mini eggs on top of the batter, trying to spread them out evenly across the batter.
Bake at 350 degrees for 20-25 minutes or until a toothpick inserted into the center comes out cleanly.
Remove from the oven and let the brownies cool in the pan until they reach room temperature. Then serve immediately!
Notes
Switch up the mix-ins – turn mini egg brownies into something completely different by swapping the chocolate eggs with M&Ms, Reese’s peanut butter cups, candied nuts, or even white chocolate chips.Clean slices – using a plastic knife is a great way to slice the brownies without having a buildup of brownie residue on the knife (although pretty delicious to pick off and eat!). You can also use a large sharp knife and wipe in between each cut.Store any leftover brownies in an airtight container for up to the three days at room temperature! I typically either put them in some sort of cookie jar, zipper top bag, or the same glass baking pan with a lid on top!To freeze, slice them into squares and freeze individually rather than all together. You can either wrap each brownie up in plastic wrap or you can layer them in a freeze bag with parchment paper between them to make it easy to grab as many you want!
