Chocolate Syrup Mug Cake

Mug cakes have been around for ages and there is a reason why… they are both quick and easy to make. And, the best part is, you make them in individual servings in the microwave to enjoy whenever you are craving chocolate cake. There is no need to get out all the ingredients to bake an entire cake; you just need some basic ingredients, a microwave-safe mug or ramekin, and a microwave.

If you opt to make this in a coffee mug, it will not fill the cup entirely, which is why I opted for a ramekin to serve mine.

How to Make a Mug Cake

To make this dessert, get out your favorite microwave-safe mug or ramekin. Add the chocolate syrup, flour, granulated sugar, melted butter, and baking powder to the mug. Mix everything together until there are no lumps. Microwave on high for 60 seconds. Remove it from the microwave and let it rest for one minute. Top the mug cake with ice cream or homemade whipped cream and more chocolate syrup

How to Make Chocolate Syrup

Get out the following ingredients to make your own chocolate syrup:

  • Cocoa powder
  • Granulated sugar
  • Salt
  • Water
  • Vanilla

Combine the cocoa powder, sugar, salt, and water in a saucepan. Put the saucepan over medium heat. Continue to whisk constantly until the mixture thickens and begins to simmer. Remove from heat after a few minutes (the longer you let it simmer, the thicker it will be) and stir the vanilla into the sauce. Refrigerate until ready to use in this recipe. 

Store any leftovers (which you will have) in the refrigerator for up to a week. Use it up to make your own chocolate milk or use it to drizzle on this Chocolate Cherry Dump Cake.  It’s so easy to make, don’t worry about running out of it!

  • Shelby says:

    I followed this recipe exactly and microwaved it for 3 minutes (60 seconds at a time) and it WOULD NOT set. It was just molten hot liquid

    • Amanda Rettke says:

      Oh my word… I would think after 3 minutes it would be hard as a rock! I have not ever encountered this specific problem so have no real advice, but I will try to replicate it and see if I can come up with any options. Thank you.
