Chewy, bakery-style chocolate chip cookies made with wholesome oat flour. Crisp edges, soft centers, and loads of melty chocolate—naturally nutty flavor without wheat flour.
Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
In a medium bowl, whisk oat flour, baking soda, cornstarch, salt, and cinnamon until evenly combined.
In a large bowl, whisk melted butter, brown sugar, and granulated sugar until smooth. Whisk in the egg and vanilla until glossy.
Add dry ingredients to wet and stir just until a soft dough forms. If the dough looks dry or crumbly, stir in milk a little at a time until it comes together.
Fold in chocolate chips and nuts (if using).
Scoop dough into 1.5 tablespoon portions and place 2 inches apart on prepared sheets. For thicker cookies, chill scooped dough for 20 minutes.
Bake 9 to 11 minutes, until edges are set and centers look slightly soft.
Cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
For gluten-free cookies, confirm your oat flour is certified gluten-free. Store in an airtight container at room temperature for up to 4 days or freeze up to 2 months.
