Preheat the oven to 180C / 160C Fan. Prepare a 9x9 inch square tin with parchment/baking paper. Allow a little extra paper so you can lift the brownies out once they are cooked.

Melt together your butter and dark chocolate over a bain marie or in the microwave until completely melted. Mix together and leave out to cool down to room temp.

Sieve together your cocoa powder and gluten free flour in a bowl. Mix briefly until combined, put to one side.

In another bowl crack 3 eggs and pour in your caster sugar. Beat together (I use an electric hand whisk) until pale in colour and almost a little frothy.

Once the chocolate and margarine mixture is cooled to room temp, pour it into your egg/sugar mixture. Fold it in, it will initially marble and then turn super chocolatey.

Next fold in the your gluten free plain flour and cocoa powder mix. Ensure it's fully folded in.

Fold in your chocolate wafer pieces.

Pour/spoon your brownie mixture into your prepared tin, smooth it over so it's even and level.

Bake for about 25 mins. Cooking for this amount of time at this temp should create incredible fudgy brownies. (You can check them during cooking they may take a little less time)

Remove from the oven and carefully push in KitKat bunnies into your brownies.

Allow to completely cool (the chocolate bunnies too!) before removing from the tin and cutting into squares. Enjoy!
