Nutella® Chocolate Chip Cookies

Preheat the oven to 350 degrees F (175 degrees C). Grease 2 cookie sheets or line with parchment paper.

Whisk both flours and baking soda together in a medium bowl.

Cream the brown sugar, chocolate-hazelnut spread, butter, and white sugar in a large bowl with an electric mixer. Beat in eggs and vanilla.

Add the flour mixture to the butter mixture; stir until a stiff dough forms. Mix in chocolate chips and rainbow chocolate chips.

Roll dough into 2-inch balls. Place 1 to 2 inches apart onto the prepared baking sheets.

Bake in the preheated oven until cookies have risen, 10 to 12 minutes. Cool on the baking sheet for 5 to 10 minutes; cookies will firm up as they cool. Remove to a wire rack to cool completely.
