Description

These One-Bowl Oatmeal Cookies are soft, chewy, and ready in under 30 minutes—no mixer and no chill time needed! Packed with old-fashioned oats and just the right amount of sweetness, they’re the perfect quick cookie fix. Add chocolate chips, raisins, or nuts if you’re feeling fancy!

 


Ingredients

  • 1/2 cup (1 stick) unsalted butter, melted

  • 1/2 cup brown sugar, packed

  • 1/4 cup granulated sugar

  • 1 large egg

  • 1 tsp vanilla extract

  • 3/4 cup all-purpose flour

  • 1/2 tsp baking soda

  • 1/2 tsp cinnamon (optional)

  • 1/4 tsp salt

  • 1 1/2 cups old-fashioned rolled oats

 

  • 1/2 cup add-ins (chocolate chips, raisins, or chopped nuts – optional)


Instructions

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

  2. Mix wet ingredients:
    In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla, and mix until well combined.

  3. Add dry ingredients:
    Sprinkle flour, baking soda, cinnamon (if using), and salt over the wet mixture. Stir until just combined.

  4. Fold in oats and add-ins:
    Stir in the oats and your choice of mix-ins (if using) until everything is evenly distributed.

  5. Scoop and bake:
    Drop dough by rounded tablespoons onto the prepared baking sheet, spacing them about 2 inches apart. Flatten slightly with the back of the spoon.

  6. Bake for 10–12 minutes, or until the edges are lightly golden and the centers still look slightly soft. Let cool on the baking sheet for 5 minutes before transferring to a wire rack.


Notes

  • For crispier cookies, bake an extra 1–2 minutes.

  • Use quick oats for a slightly softer texture.

 

  • Cookies will keep in an airtight container for up to 5 days or can be frozen for later!
