1. Preheat the oven to 180°C (350°F). Line two baking sheets with baking parchment and set aside.

2. In a large bowl beat the butter on high speed until light in color. Add the peanut butter and two sugars and mix until all is well combined. Add the egg and vanilla extract and mix until well combined.

3. Combine flour, baking powder and salt and add the mixture to the bowl – mix until just combined. Add the chocolate chips and fold them in (force them in if they try to escape). Form little balls (approx. the amount of a tablespoon) and press them together to get flattened cookies.

4. Place the dough portions on the baking sheets with enough space inbetween. Bake the cookies for about 10-12 minutes – they should have some color but still be soft in the center. Take them out of the oven and let them cool down on the baking sheets for about 5 minutes – then transfer to a wire rack and let cool down completely.
