Peanut Butter M&M Cookies
Deliciously thick, chewy, and soft peanut butter loaded cookies that are stuffed full of chocolate M&M's. These are the absolute BEST peanut butter cookies!
Servings: 16 - 18 cookies
Ingredients
- 2 cups (250g) plain/all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- 2 teaspoons cornflour/cornstarch
- ¼ teaspoon salt
- ½ cup (115g) unsalted butter melted
- ¾ cup (150g) light brown sugar
- ¼ cup (50g) caster/granulated sugar
- 1 large egg
- 2 teaspoons vanilla extract
- ½ cup (125g) smooth peanut butter
- 1 cup (170g) chocolate M&M's
Instructions
- Preheat the oven to 180C/350F/Gas 4. Line a baking tray with parchment paper or a silicone mat, and set aside.
- Whisk together the flour, baking powder, baking soda, cornflour, and salt. Set aside.
- In a separate large bowl, whisk together the melted butter and sugars until combined.
- Add the egg, vanilla, and peanut butter, and mix until combined.
- Add the dry ingredients, and mix until just combined. Fold in the M&M's.
- TIP: If you find the cookie dough too crumbly, add milk (1 tablespoon at a time) and mix until it comes together and is easier to manage.
- Roll the dough into 2-oz balls (or use a medium cookie scoop), and place onto the prepared baking tray. Bake for 10 - 12 minutes.
- Allow to cool on the baking tray for 5 - 10 minutes before transferring them to a wire rack to cool completely.
