Equipment

My 9" square baking tin

Ingredients

100 g caster sugar
100 g light brown sugar
140 g butter melted
150 g gluten free plain flour
1 tbsp cornflour cornstarch
250 g peanut butter (smooth or crunchy - but ideally a more creamy peanut butter)
1 egg
1/2 tsp bicarbonate of soda
1/2 tsp vanilla extract
1/4 tsp xanthan gum (if you don't have it, it doesn't matter so much for this recipe)
75 g chocolate chips
50 g Reeses chips if you don't have these add more chocolate chips
90 g Reeses Peanut Butter Cups I used the mini ones

Instructions

Preheat your oven to 160C Fan / 180C and prepare a 9x9 inch square baking tin with non-stick baking paper.
Place your caster and light brown sugar into a bowl. Add your cooled melted butter and mix throughly until combined. After I've mixed mine, I leave it briefly until it stiffens up more.
Add in your egg, vanilla and mix in until combined.
Next add your peanut butter. Mix until smooth and combined - I use an electric hand mixer for this.
Then add in your gluten free flour, corn flour, bicarbonate of soda and optionally a 1/4 tsp of xanthan gum. Mix together until fully combined.
Mix in your chocolate chips and if you have them, your Reeses chips and chopped up Reeses peanut butter cups. Ensure they are evenly dispersed.
Spoon your mixture into your square tin. Press it in with your hands and the back of a spoon so it gets right to the edges and is level.
Press in some additional chopped up peanut butter cups and chocolate chips.
Place in the oven for between 18-22 minutes. You can leave them in longer too but I love a soft peanut butter cookie bar!
Remove from the oven and allow to cool in the tin till they firm up, then remove from the tin and allow to finish cooling on a rack.
Once cooled, chop into squares and enjoy!

Notes

You don't have to use any Reeses peanut butter cups or chips in these. You can just make them with chocolate chips and they would be amazing too, and still super peanut butter like! This is the best way to make them dairy free too (+ vegan with an egg replacer).
