Preheat your oven to 180°C/160°C(fan)/350°F/Gas 4.
Mix together 150 g Butter, 75 g Light brown sugar and 75 g Caster sugar until light and fluffy.
Add 1 Egg and 1 teaspoon Vanilla extract. Fold gently until combined.
Add 190g Plain flour, 0.5 teaspoon Baking powder, 100 g Milk chocolate chips and 150 g Mini eggs. Fold everything together until combined and a cookie dough is formed.
Divide the mixture into 12 and roll into balls. Put onto a large baking tray with as much space between the balls as possible. You may need to do this in separate batches.
Bake for 10 minutes, until the edges have started to get crispy, but the cookies are still soft in the middle. Press some more mini eggs into the tops of the cookies for decoration.
Leave to cool on the tray for 2 minutes and then transfer to a wire rack to cool for a few minutes more before eating the cookies warm.
Notes
To make portioning your cookies out easier, you can use an ice cream scoop.
We chopped up the mini eggs and mixed them in with the cookie mixture. However, if you want some extra whole mini eggs on top like you can see in the photos, then you need to reserve some of the mini eggs. You can either gently place 2 on top of the dough ball before it goes in the oven, or once the cookies are out of the oven and cooling on the tray, you can gently push a couple of mini eggs into each cookie.
You can use milk, dark or white chocolate chip cookies in this recipe.
Don't try to cut the mini eggs with a knife, as that is near impossible. Instead, put them in a freezer bag and smash them with a rolling pin.
