If you love mug cakes, and sometimes crave s’mores, this is for you.

And for me. I do crave the smell of marshmallows roasting over an open fire. The crackle and pop and the gathering of those around a summer fire pit.

It’s not easy to capture the bonfire indoors, but you can satisfy those flavor cravings with this simple smores mug cake.

And make it for one… or two.

It’s a small batch dessert that’s utterly delicious. Much like our popular mug cakes, this is special.

The chocolate cake base alone is worth making. It’s so moist, tender, and chocolaty delicious.

  • Two minutes to utterly delicious

S’mores Mug Cake Ingredients

  • All-purpose flour: Be careful to measure and level the flour. Too much flour can cause the cake to be dense. 
  • Unsweetened cocoa powder: Both natural unsweetened cocoa powder and dutch-processed cocoa powder work equally well. 
  • Granulated sugar: Helps bring out the chocolaty flavor.
  • Baking powder: Essential to help the mug cake rise. 
  • Salt: Ya pinch of salt enhances the flavor. 
  • Milk: I always use whole milk because it’s what I keep on hand and gives baked goods a richer taste. That being said, 2%, 1%, skim, or even almond milk would work fine too.
  • Oil: You can use canola, vegetable, or melted coconut oil. 
  • Vanilla extract: Use pure vanilla extract, if possible. 
  • Semi-sweet chocolate chips: I love the extra chocolate flavor they add, so I highly recommend using some if you have them on hand.

HOW TO MAKE A MUG CAKE

You will need a 12-ounce or larger microwave-safe mug. I like to grease the mug with a bit of butter or nonstick spray.

Whisk together the dry ingredients before adding the milk, oil, and vanilla extract; stir until just combined. 

When I’m making one mug cake, I mix the ingredients in the mug. When I’m making 2 or more, I like to use a separate bowl.

Sprinkle the tops of the unbaked mug cake with chocolate chips. Microwave for 1 to 2 minutes. For me, 1 minute and 10 to 15 seconds is always perfect.

You want to microwave the cake just until it’s set. Otherwise, it can become dry very quickly.

How to Roast Marshmallows in the Oven

It’s so easy… and no campfire is needed. Set the oven to broil and raise the rack to near the top.

Then, simply add large marshmallows to a baking pan. Watch carefully, but broil the marshmallows for 10 to 15 seconds, or until nicely browned. 

With a spatula, flip the marshmallows over and broil for another few seconds. Remove from the oven promptly.
