Whether you’re in the mood for a quick treat or you’re looking for something easy and special to make for Valentine’s Day, this flourless chocolate mug cake should do the trick.
For best results, be sure to read the recipe notes before making your cake.
- 1/4 cup semisweet chocolate chips
- 1 tbsp heavy cream
- 1/2 tbsp dutch processed cocoa powder
- 1 large egg
In a large microwave-safe mug (at least 12 oz), add chocolate chips and heavy cream. Heat for about 40 seconds in the microwave and then whisk until chocolate is completely melted and smooth. Add in remaining ingredients and whisk vigorously so that you do break down the egg. Whisk until the egg is fully incorporated and the batter is smooth.
Microwave cake for about 1 minute. Cake will rise extremely high while in the microwave, probably passing the top of the mug, and will the sink back down once the cooking has stopped. Cake should be solid and completely cooked but slightly wet around the edges. Rest the cake for about 20 minutes so that the flavors fully develop.
You can remove cake and place it into a smaller cup or bowl as the cake will continue to shrink and condense as it cools. Top with powdered sugar and fresh fruit before serving.
- This cake cannot be cooked in a small mug even though the final result will be smaller than a regular sized mug. When it cooks it will rise extremely high so you must make it in an oversized mug otherwise it will spill and make a mess in your microwave. Once it’s cooked the cake will shrink. For a pretty presentation, you can transfer the cake to a smaller mug or bowl. For the photos in the post, I actually cut them in half and stuffed each half into small cups.
- Make sure you give the cake some time to rest so the flavors fully develop. After it cooks the chocolate flavor will not yet be as rich, and it might taste slightly eggy, but that goes away after you give it some time to cool.
- I prefer my chocolate desserts less sweet and with a deep chocolate flavor. If you like sweeter desserts, you can always add a little sugar to the batter or top the cake with frosting or a glaze before serving.
