Perfect for when you just want one dessert not three dozen, this Double Chocolate Mug Cookie Recipe will satisfy your sweet tooth – it’s an easy microwave cookie recipe created from my double chocolate chip cookies.
It’s a cookie. For one. In a mug! My Double Chocolate Chip Mug Cookie Recipe is my favorite cookie recipe scaled down to one single serving. Sometimes you just want a quick and easy dessert without chilling, baking, or leftovers and this mug recipe is one of my favorites (besides my mug cake recipe and my mug brownie, that is). The chocolate and richness of this cookie make it taste like a brownie!
Important Ingredients
- Butter: I use melted unsalted butter but you can substitute vegetable oil if you prefer. You’ll also want to add a pinch of salt.
- Cocoa Powder: You can use any unsweetened cocoa powder (or Dutch-process).
- Egg Yolk: The cookie needs some extra fat and structure, and it’s really hard to divide eggs into fractions. That’s why I use an egg yolk instead. Egg substitutions: Use 1 tablespoon milk or non-dairy milk or water, or 1 tablespoon egg beaters.
How to make a cookie in a mug
- Adapting full recipes to small ones is where my nerdy math background (summa cum laude in mathematics, thank you very much) comes in handy. I can convert fractions of cups into tablespoons and teaspoons and divide by 12 or 36 or whatever. It’s actually quite simple…which I know just made about 3/4 of you roll your eyes.
- Use at least an 8-ounce coffee mug or microwave safe-mug. The batter won’t fill it up completely but you don’t want it to overflow. You can also use a ramekin.
- Just stir all the ingredients together and then add to your mug or ramekin.
- Microwave for about 40 seconds, longer if you want it more done. All microwaves cook differently so you might have to play with the time.
- Sometimes I add a scoop of peanut butter on top for extra flavor.
Expert Tips
- This is meant to serve one, so no storing instructions needed. However if you don’t finish it, just cover with plastic and store at room temperature.
- The beauty of making a cookie in a mug is the ratios are easier to mess with. Leave out the cocoa powder and add 1 extra teaspoon flour and you’ll have a chocolate chip cookie in a mug!
- All microwaves cook differently, and all tastes are different. 30 seconds makes a gooey cookie in my microwave. You may need to cook it up to 60 seconds but play with it and test it a bit so it’s not dry.
- Serve plain or with a scoop of vanilla ice cream.
