Ingredients
Scale
Wet Ingredients
- 1/2 cup butter (115 g)
- 1/2 cup granulated sugar (100 g)
- 1/2 cup light brown sugar (110 g)
- 1/2 cup peanut butter (130 g)
- 1 egg
- 1 teaspoon vanilla extract (5 ml)
Dry Ingredients
- 1 cup all-purpose flour (120 g)
- 1 1/4 cups old-fashioned rolled oats (112 g)
- 1/4 teaspoon salt (1.5 g)
- 1/2 teaspoon baking powder (2 g)
- 1/2 teaspoon baking soda (2.5 g)
Add-ins
- 3/4 cup M&M candies (130 g)
- 1/2 cup semi-sweet chocolate chips (90 g)
Instructions
- Preheat Oven: Preheat your oven to 350 degrees Fahrenheit to ensure it reaches the right temperature for baking the cookies evenly.
- Cream Butter and Sugars: Using a mixer, cream together the butter, granulated sugar, and brown sugar for 2-3 minutes until the mixture is light and fluffy, which helps create a tender cookie texture.
- Add Peanut Butter, Egg, and Vanilla: Incorporate the peanut butter into the creamed mixture and mix well, then add the egg and vanilla extract, beating to combine all wet ingredients smoothly.
- Combine Dry Ingredients: In a separate bowl, stir together the all-purpose flour, old-fashioned rolled oats, salt, baking powder, and baking soda. Measure the flour carefully by spooning it into the cup and leveling it off for accuracy.
- Mix Wet and Dry Ingredients: Add the dry ingredient mixture to the wet ingredients and stir until just combined to avoid overworking the dough.
- Fold in Chocolate Chips and M&M’s: Gently stir in the chocolate chips and M&M candies, distributing them evenly throughout the cookie dough.
- Scoop and Bake: Using a 1-inch cookie scoop, place dollops of dough onto a baking sheet and bake at 350 degrees for 10-12 minutes. Bake a little longer if making larger cookies but avoid overbaking; cookies should look just set when done.
- Cool Cookies: Remove the cookies from the oven and allow them to cool completely on the baking pan to set properly and develop their chewy texture.
Notes
- Do not overbake the cookies; they should look set but still soft to maintain chewiness.
- Measuring flour correctly is important: spoon into the measuring cup and level off to avoid dry, dense cookies.
- Allow cookies to cool completely on the pan — this helps the cookies firm up and enhances their chewy texture.
- Optional: For different flavors, consider swapping M&Ms for peanut butter chips or adding chopped nuts.
