Ingredients:
- 1 cup (225g) unsalted butter, softened
- 1 cup (200g) dark brown sugar, packed
- 0.5 cup (100g) granulated white sugar
- 1 large egg, room temperature
- 1 tbsp pure vanilla extract
- 1.5 cups (190g) all-purpose flour
- 1 tsp baking soda
- 1 tsp ground cinnamon
- 0.5 tsp sea salt
- 3 cups (270g) old fashioned rolled oats
Instructions:
- Cream the fats. Beat 1 cup softened butter with 1 cup dark brown sugar and 0.5 cup white sugar for 3 minutes until pale and fluffy.
- Incorporate the liquids. Add 1 large egg and 1 tablespoon vanilla extract. Beat 1 minute until the mixture looks velvety.
- Whisk dry ingredients. In a separate bowl, stir 1.5 cups flour, 1 teaspoon baking soda, 1 teaspoon cinnamon, and 0.5 teaspoon sea salt until fully blended.
- Combine the bases. Pour the flour mixture into the butter mixture. Mix on low until just a few streaks of flour remain.
- Fold in texture. Stir in 3 cups old fashioned oats using a spatula. Mix until the oats are evenly distributed.
- Portion the dough. Scoop rounded tablespoons of dough onto a lined sheet. Space them 2 inches apart to allow for spreading.
- Bake with precision. Place in the oven for 10 minutes until edges are slightly browned.
- Rest on tray. Leave cookies on the hot baking sheet for 5 minutes. They will finish cooking via carryover heat.
- Final cooling. Move to a wire rack until completely room temperature.
