Easter brookies are a Cadbury's mini egg cookie bar base, topped with a fudgy Cadbury mini creme egg brownie. Why choose between cookies and brownies when you can have both!?
Mix together the cookie batter as normal, creaming sugars and butter before adding egg and vanilla. Then adding in dry ingredients before folding in the mini eggs.
Whisk the wet ingredients together and stir the dry ingredients separately. Add the dry to the wet and mix to create a thick batter. Spread this over the cookie layer.
