Ingredients
- 1 cup all-purpose flour
- 1/2 cup oat flour (or extra all-purpose flour)
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup unsalted butter, softened
- 1/2 cup brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 3/4 cup dark chocolate chips
- 1/2 cup chopped walnuts
Instructions
Preheat the Oven:
Set your oven to 375°F (190°C) and line a baking sheet with parchment paper or a silicone baking mat.
Mix the Dry Ingredients:
In a medium bowl, whisk together the all-purpose flour, oat flour, baking soda, and salt. Set aside.
Cream the Butter and Sugar:
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This will take about 3-4 minutes with an electric mixer.
Add the Wet Ingredients:
Beat in the egg and vanilla extract until fully combined.
Combine Wet and Dry Ingredients:
Gradually add the dry ingredients to the wet ingredients and mix until just combined. Be careful not to overmix; the dough should be thick and slightly sticky.
Add the Chocolate and Walnuts:
Fold in the dark chocolate chips and chopped walnuts, ensuring they’re evenly distributed throughout the dough.
Shape the Cookies:
Scoop out large portions of dough (about 3 tablespoons per cookie) and form into thick, round balls. Place them on the prepared baking sheet, spacing them about 2 inches apart.
Bake:
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown but the centers are still soft. Keep an eye on them—baking time may vary depending on your oven.
Cool & Enjoy:
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy the thick, gooey texture and rich flavors!
