Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • 1 cup white chocolate chips
  • 1 cup crushed pretzels
  • 1 cup potato chips, lightly crushed
  • 1 cup M&M’s candies (or holiday mix-ins)
  • 1/2 cup chopped nuts (optional)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Line baking sheets with parchment paper.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This takes about 3 minutes.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix the dough.
  6. Fold in all your mix-ins: semi-sweet chocolate chips, white chocolate chips, crushed pretzels, crushed potato chips, M&M’s, and nuts if using. Mix until evenly distributed.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. For a bakery style cookie, press a few extra chips or candies onto the tops of the dough balls.
  8. Bake for 9 to 12 minutes, or until the edges are golden brown and the centers are set but still look slightly soft.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For a chewy bakery style cookie, slightly underbake them. The residual heat will finish the cooking process.
  • To make the Holiday Cookie Variation: Substitute the standard M&M’s with red and green M&M’s or festive holiday sprinkles. You can also swap the white chocolate chips for peppermint baking chips.
  • This is a highly customizable cookie recipe. Feel free to swap out any chips or candies for your favorites, like butterscotch or peanut butter chips.
  • For a sweet and salty cookies experience, ensure your pretzels and potato chips are lightly salted.
