One-Bowl Kitchen Sink Cookies

These simple cookies come together in one bowl without a mixer, and the best part is they can be packed with whatever mix-ins on hand. We like to spoon the cookie dough into bowls and let people build their own perfect cookie with different flavor combinations. Thanks to the higher ratio of dark brown sugar, they bake up extra chewy—perfect for family night.

1/2 cup unsalted butter (1 stick), softened to room temperature

1 cup dark brown sugar

1/4 cup granulated sugar

1 teaspoon vanilla extract

1 egg, cold from the refrigerator

1 1/2 cups all purpose flour

1/2 teaspoon baking soda

1/2 teaspoon baking powder

Mix-ins & Toppings (all optional):

Chopped chocolate bars (dark, milk, white)

Small candy pieces, such as M&Ms, Reese’s Pieces or soft caramels

Crushed cookies, such as Oreos or Biscoff wafers

Crushed cereal, such as corn flakes or Fruit Loops

Crushed potato chips or mini pretzels

Mini marshmallows

Rainbow sprinkles

Malted milk powder

Flaky sea salt

Suggested cookie flavor combinations:

• Malted Milk & Cookies – Crushed Oreo cookies and sprinkle of malted milk powder
• Salted Caramel Corn Flake – Soft caramel candies, crushed cornflakes and a pinch of flaky salt
• Triple Chocolate Chunk – Chopped white, dark, and milk chocolate bars

Preheat oven to 350°F.

In a large mixing bowl, vigorously whisk softened butter, dark brown sugar, granulated sugar, and vanilla extract for about 1 minute until thoroughly mixed and whipped. (If the butter and sugar are clumping on the whisk, the butter isn’t soft enough. Allow to sit out at room temperature until it easily whips.)

Add the egg and whisk for another 30 seconds. Add the flour, baking soda and baking powder. Using the whisk, gently mix the dry ingredients into the wet. Then, switch to a wooden spoon or spatula and begin stirring dry ingredients into the butter mixture. Keep stirring for about 30 seconds, until it goes from dry crumbles to a cohesive dough. 

Spoon 1/4 cup-sized cookies into a small bowl and add mix-ins. Place cookies onto the unglazed side of a pizza stone and bake in preheated oven for 12 minutes until the cookies are just starting to brown along the edges.

Remove from the oven and let sit for 15 minutes before serving.
