Ingredients:
- 1 ¾ cups (220g) all-purpose flour
- 1 tsp (3g) cornstarch
- 1 tsp (5g) baking soda
- ½ tsp (3g) sea salt
- ½ cup (115g) unsalted butter, softened
- ½ cup (125g) creamy peanut butter
- ¾ cup (150g) light brown sugar, packed
- ¼ cup (50g) granulated white sugar
- 1 large egg, room temperature
- 1 tsp (5ml) vanilla extract
- 1 cup (150g) Reese’s Peanut Butter Cups, chopped
- ½ cup (90g) Reese’s Pieces
- ½ cup (85g) semi-sweet chocolate chips
Instructions:
- Whisk the 1 ¾ cups flour, 1 tsp cornstarch, 1 tsp baking soda, and ½ tsp sea salt in a medium bowl.
- Cream the ½ cup softened butter, ½ cup creamy peanut butter, ¾ cup brown sugar, and ¼ cup white sugar in a large bowl. Beat for 3 minutes until pale and fluffy.
- Add the 1 large egg and 1 tsp vanilla extract to the creamed mixture. Scrape the sides of the bowl to make sure everything is fully incorporated.
- Switch your mixer to low and slowly add the dry ingredients to the wet. Mix only until the last streak of flour disappears.
- Fold in the 1 cup chopped Reese’s Cups, ½ cup Reese’s Pieces, and ½ cup chocolate chips using a spatula.
- Scoop 2 tablespoon mounds of dough onto a parchment lined tray and chill in the fridge for at least 30 minutes. Wait until the dough feels firm to the touch.
- Preheat your oven to 350°F (180°C) while the dough chills.
- Space the chilled dough balls 2 inches apart on a baking sheet. Bake 9 to 11 minutes until the edges are golden and the tops look slightly underdone.
- Remove from the oven and let them sit on the hot pan for 5 minutes.
- Transfer to a wire rack to cool completely. Wait until they are cool to experience the full shattering texture of the Reese's Pieces.
