One Big Oatmeal Cookie Recipe

Yield: 1 cookie
Prep Time: 5 minutes
Cook Time: 15 minutes
Total Time: 20 minutes
When a cookie craving strikes in the mid-afternoon or after the kids have gone to bed, this is the cookie I make. It's basically a paired down version of my brown sugar oatmeal cookies, but it's made in one bowl and mixed with a fork so it's as easy as can be.
I have to warn you, this is a big cookie! If you want to share this with someone, or hide one away for later, feel free to make two cookies with the dough.

Ingredients

  • 2 tablespoons butter, at room temperature
  • 2 tablespoons brown sugar
  • 1 large egg yolk
  • ½ teasoon vanilla
  • ¼ teaspoon molasses
  • 4 tablespoons all-purpose flour
  • ⅛ teaspoon EACH: baking soda and cinnamon
  • 1 pinch salt
  • 4 tablespoons quick oats
  • 1 tablespoon EACH: chocolate chips and raisins

Instructions 

  • Preheat your oven to 350 degrees Fahrenheit. In a small bowl (like a cereal bowl), microwave the butter for 10 seconds - it should not melt.

  • Roll the dough into a ball and place it on your baking sheet. Use your hand to flatten it out so that it is about 4 inches round. OR make two cookies and flatten them out to 3 inches around.

  • Bake for 14-16 minutes, until the edges look crispy and the center is cooked through. Let the cookie cool for 10-15 minutes on the baking sheet - the hardest part!
    If you're making two cookies, bake them for 10-12 minutes.

Notes

Make two cookies: If you'd rather make two normal-sized cookies, go for it! They will take about 10-12 minutes to bake. 
Egg: If you'd like to omit the egg, mix the baking soda with 1 tablespoon of hot water and add that with the flour in step 3. It works quite well, but we liked the flavor better with the egg yolk.
Raisins: If they are not your thing, swap them for more chocolate chips.
