These Oat Flour Chocolate Chip Cookies are lightly crisp on the outside with a perfectly soft and chewy center, every bite is full of melty chocolatey goodness. You would never know that they are actually gluten-free and made with oat flour instead of regular flour.
Using a hand mixer or stand mixer fitted with a paddle attachment, cream together butter, brown sugar, and granulated sugar on high speed until pale and fluffy.
Scrape the sides of the bowl with a spatula. Add egg and vanilla. Beat the mixture until well combined.
Add oat flour, baking soda, and salt. Beat on low speed just until combined. Don't overmix.
Add chocolate chips, leaving a little bit to decorate on top. Mix with a spatula until well combined.
Chill for at least 30 minutes or up to 3 days in the fridge. Don't skip or the cookies will spread during baking.
When ready to bake, preheat the oven to 350℉/180℃. Line baking sheets with parchment paper.
With a 1.6 inch/4 cm ice cream scoop (about 1.5 tablespoons), drop the dough on prepared baking sheets, leaving 2 inches apart.
Place some chocolate chips on top of each cookie to decorate.
Bake for 9-11 minutes.
Immediately after removing the cookies from the oven, sprinkle sea salt flakes on top of the cookies.
Let cookies cool on the pan for 5 minutes before transferring them to a cooling rack to cool completely.
