Mug Cookie: Ingredients & Substitutions
- Salted Butter. Unsalted butter & coconut oil are both good substitutes.
- Granulated sugar. Use organic cane sugar if you’d like.
- Light brown sugar. Dark brown sugar or coconut sugar are great choices.
- Mini chocolate chips. I prefer mini chips because they spread well throughout the dough so there’s chocolate in every bite. You can use regular-sized chips, chopped chocolate bars, etc.
How to Make a Cookie in a Mug
Let’s walk through how to make a cookie in a mug together – and you can watch the video if you need some more help! The best thing about this recipe is that it’s all made in the mug! So easy!
First, melt the butter in the mug.
Then, let it cool slightly by stirring it a few times, and mix in the sugar, brown sugar, vanilla, and egg yolk.
Next, add the flour, salt, and baking soda and stir to combine.
Then, stir in the mini chocolate chips until they’re evenly distributed throughout the dough.
Cook in the microwave for 55 seconds. Then let the mug cookie cool before serving.
Serve
Serve this cookie in a mug nice and warm with a sprinkle of flaky sea salt or a scoop of vanilla ice cream. We also love topping it with some homemade whipped cream!
Store
You really shouldn’t need to store this because it’s made to be eaten by one person in a single serving. However, if you don’t finish it, just cover the top of the mug with plastic wrap and store it in the fridge for up to 3 days. Reheat in the microwave for a few seconds.
