Happy Halloween everyone! I am excited to pass out candy later this evening and see all the cute costumes. I saw these children-sized mugs at Sur la Table and just had to get them. I knew exactly what to use them for! My Leftover Halloween Candy Mug cake.

I use plain chocolate bars as the base of the cake and then add more chopped candy into the cake. You can choose whatever candy you want, though I try to stick to chocolate coated candy bars. It’s a fun and easy way to get rid of some of your leftover Halloween candy or to make for a Halloween party.

The cake fits exactly into a small mug, though I don’t actually recommend making them in a tiny mug as it’s really hard to mix the batter and it may overflow while cooking. I cooked this is a larger mug and then plated it in the smaller Jack-O-Lantern mug.

  • In a large, microwave-safe mug, add 1/4 cup chocolate and 3 tbsp of milk. Heat in microwave for about 30 seconds. Stir with a mini whisk to completely melt chocolate into the milk. If chocolate is not completely melted, heat an additional 10 seconds and whisk again.

  • Dark chocolate or milk chocolate bars work for this recipe.
  • I recommend sticking to chocolate-based candy bars.
