Double chocolate cookies are my absolute favorite. This single serving chocolate cookie is for when the cookie craving hits, but you can’t be bothered to make a whole batch of cookies. It’s fudgy, thick and stuffed with melty chocolate chips. The outside is slightly crispy and the middle is gooey. The dough can be made with fork – no mixer required – and there’s no need to chill the dough.

To say this is a recipe for one, double chocolate cookie might be stretching the truth a bit because it’s a very, very large cookie. But I won’t judge you if you make it for yourself on a Friday night.

Making a Single Serving Chocolate Cookie: Step by Step Photos

Here’s the step-by-step details on how to make your rich and gooey cookie.

1. Start by preheating the oven to 350F (180C) and lining your cookie sheet.
2. Whisk together 2 tablespoons of melted butter with 1/4 cup light brown sugar.
   • You can use 2 tablespoons dark brown sugar and 2 tablespoons of white sugar if that’s all you have on hand. You want to whisk until the butter no longer looks separate.
3. Then whisk in 1 large egg yolk (discard the egg white) and 1/4 teaspoon vanilla extract. Make sure to whisk until the mixture looks even – AKA you don’t see lumps of egg.

4. Stir in the dry ingredients: 6 tablespoons all-purpose flour, 2 tablespoons cocoa powder, 1/4 teaspoon baking powder and a pinch of salt. At first it will look like the dry ingredients won’t mix in – but with a little extra stirring they will all combine without a problem.
   • If your cocoa powder is very lumpy, then I recommend sifting it into the bowl.
5. Then stir in 2 tablespoons of chocolate chips. I like to use dark chocolate chips – but feel free to use whatever your preference is.

6. Form the dough into a large ball (about 3/4 – 1 inch thick in the middle) and place on a lined cookie sheet.
7. Bake in the oven for about 13-15 minutes, or until the top looks set. Remove from the oven and place extra chocolate chips on top of the cookie for a truly decadent look.

Important Tip: Make sure to measure the ingredients using a measuring cups and spoons, and not kitchen utensils. When measuring the flour and cocoa powder especially, make sure to level off the top of the tablespoon, so that it isn’t heaping. Using heaping tablespoons of chocolate chips is definitely OK though 🙂

Chewy, thick, fudgy and a little gooey – this double chocolate cookie for one is perfection. It’s the perfect chocolate treat for when you’re in desperate needof something decadent. And if you’re looking for more single serving cookies and late night treats, then be sure to try:
