Ok, I said, I forgot about peanut butter... for a moment. It lasted exactly until just now! Here's one for all the addicts!
(slightly adapted from: Trish Deseine - I love Cake)
1 teaspoon baking powder
1 teaspoon salt
225g butter, soft
225g peanut butter, smooth or crunchy
2 teaspoons vanilla extract (if you don't have vanilla extract, substitute with a teaspoon of vanilla sugar or so)
340g brown sugar
3 eggs, beaten
Preheat the oven to 180°C.
Sieve the flour into a bowl together with the baking powder and the salt. In another bowl, combine butter, peanut butter and vanilla extract with the electric hand mixer. While beating, add the sugar. Add half of the flour, then the eggs and then the rest of the flour.
Form scoops of about 3cm diameter out of your dough and place them onto baking trays line with parchment paper. Leave about 7-8cm distance between the cookies. Press the tines of a fork into the scoops crosswise so that you get a grid pattern.
Bake the cookies for about 15 minutes (I baked them for about 12 minutes or so) until the surface is dry and the downside golden-brown. Take them out of the oven, let cool for about 5 minutes on the tray, then transfer to a wire rack and let cool completely.
I got 26 cookies.
