Preheat your oven to 160C Fan / 180C and prepare a 9x9inch square tin with non-stick baking paper.
Melt together your butter and chocolate in a microwave or over a bain
marie until completely melted. Mix together and leave out to cool down
to just warm / 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 paler
in colour and almost a little frothy.
Once the chocolate and butter mixture is cooled to room temp, pour it into your egg/sugar mixture. Fold it in with a spatula - it will
initially marble and then turn super chocolatey. Add in your mint/orange extract, if using.
Next fold in the your gluten free plain flour and cocoa powder mix. Ensure it's fully folded in.
Fold in your white chocolate chips.
Pour/spoon your brownie mixture into your prepared tin and smooth it over so it's even and level.
Bake for about 25 mins. The brownies will wobble slightly upon removing from the oven but will firm up as they cool. If you want them even more gooey, cook for 5 minutes less, if you want a firmer brownie, cook for slightly longer. I find with brownies all ovens seem to really vary.
Remove from the oven and carefully push your KitKat Santas and Festive Friends into your brownies.
Allow to completely cool (the chocolate Santas etc too!). Remove from the tin and cut into squares. Sprinkle over your crushed candy cane (be careful - the edges can be sharp!) if using.
Enjoy!
