These Marry Me cookies are impossible to resist! Made with chocolate chips, oats, cinnamon, and brown butter, they're a rich, decadent treat.
In a large saucepan, melt the butter over low-medium heat until foamy. Stir constantly and cook until it’s brown and smells nutty, about 5-7 minutes. Remove the pot from the heat and let it cool for 2-3 minutes.
In a large mixing bowl, combine the brown and white sugars. Add the browned butter and whisk it by hand until blended and smooth. Place the bowl in the fridge for 10-15 minutes.
When the brown butter and sugars have cooled, add the egg, egg yolks, and vanilla and whisk well until fully combined.
In a separate bowl, stir the flour, oats, baking soda, salt, and cinnamon to distribute the ingredients evenly.
Add half of the dry mixture to the wet ingredients and stir with a spatula until it's mostly combined. Then, add the rest of the dry ingredients, chocolate chips, and chopped nuts (if using), and stir until it's just combined.
Portion the cookie dough into 2 tablespoon balls. Arrange them on one parchment-lined baking sheet (without spacing), cover with plastic, and chill for 30 minutes.
Preheat the oven to 325 degrees Fahrenheit (160°C) and line a second baking sheet with parchment paper.
Divide the firm cookie dough balls between the 2 sheets, leaving at least 2 inches between each one. For thicker cookies, leave them as is. For thinner cookies, flatten them slightly with the bottom of a glass. Bake for 10-12 minutes until golden around the edges.
Let the cookies cool on the baking trays until they're firm enough to move. Then, transfer them to a wire rack to cool completely. Serve and enjoy!
