Whisk together most of your dry ingredients – the flour, baking soda, and sea salt in a bowl and set aside.
¾ cup + 1 tablespoon All-Purpose Flour, ½ teaspoon Baking Soda, ¼ teaspoon Salt
Place the butter, lemon zest and sugar in your mixing bowl and using the paddle attachment, cream until you reach a fluffy, rather pale color. This should take about 3-5 minutes. Make sure to take a second to scrape down the bowl before then adding your egg and vanilla - mixing for an additional few minutes until combined.
½ cup Unsalted Butter, ½ cup Brown Sugar, 1 Egg, 1 teaspoon Vanilla Extract, 2 Lemons
Slowly add the mixed dry ingredients in two separate stages, mixing until your ingredients have JUST fully combined. Then, add oats and mix until combined before doing the same with the blueberries.
1 ⅔ cups Rolled Oats, 1 ⅓ cup Blueberries
When ready to bake, preheat the oven to 350 degrees Fahrenheit and prepare your baking tray with parchment paper.
Using a large-sized cookie scoop, place your preferred number of cookies onto a baking sheet, press the tops down slightly and bake for about 13-15 minutes depending on the size of your cookies. For medium-sized cookies, bake for 12 minutes. Remove from the oven, use a large cookie cutter to scoot cookies into a perfect circle if desired, and let cookies sit undisturbed for 3-5 minutes - add flakey sea salt here if preferred! Then, transfer to a wire rack and allow to cool before enjoying!
