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. Add the chopped chocolate-coated peanuts and fold in. Place in the fridge for about 30 minutes.

2. Preheat the oven to 350°F (180°C). Line a baking sheet with baking parchment. Use a cookie scoop or tablespoons and place dough portions with some space in between on the baking sheet (keep remaining dough in the fridge) and bake for 10-12 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 the remaining dough.
