Peanut Butter Cookies with Chocolate Chips and Sesame

4 days off from work! I treated myself to an extended weekend. Baking, of course, is part of my relaxation program :-) Here comes a modification of a cookie recipe I have recently posted.

Recipe
(adapted from here)

175g peanut butter (smooth or crunchy)
75g unsalted butter, melted
200g brown sugar
2 medium eggs
2 tsp vanilla extract
60g sesame seeds, plus extra to finish
125g plain flour
½ tsp bicarbonate of soda
60g dark chocolate, in pieces

Preheat the oven to 180°C and line two baking trays with parchment paper.

Beat together the peanut butter, melted butter and sugar until smooth, add the eggs and vanilla, and beat again. Stir in the seeds, chocolate, flour and soda until smooth. Line a tray with nonstick baking paper, spoon 30g blobs of dough on to it spaced 4-5cm apart, sprinkle with more sesame seeds and bake for 12-14 minutes. Let cool on a wire rack.
