1. Add the butter and sugar to a large bowl and mix until light and fluffy. Add the egg and vanilla extract and mix until well combined. Add the peanut butter and mix in. Mix the flour with baking powder and baking soda and add to the bowl – mix until just combined. Place the dough in the fridge for about 30-45 minutes.

 

2. Preheat the oven to 350°F (180°C). Line a baking sheet with baking parchment. Divide the dough into 18 dough portions, shape into balls and roll in the cane sugar. Flatten the balls a bit and place with some space in between on the baking sheet (keep remaining dough in the fridge) and bake for 8-9 minutes. Take out of the oven and let cool down a bit on the baking sheet, then transfer to a wire rack and let cool down completely. Repeat with remaining dough.
