Cooking with Less Kilowatts: Leftover Halloween Candy Mug Cakes

It’s cake! It’s candy! It’s Halloween in a mug!

This week’s low energy use recipe is a quick and easy “mug cake!” As in, it’s literally prepared in the microwave in less than one minute using a mug, and it’s is the perfect recipe to help your family re-purpose any leftover Halloween candy from this weekend’s trick or treating.

This might be the first time in our Cooking with Less Kilowatts series that I actually suggest to do everything in the microwave, but trust me, this recipe is so delicious you will feel like you just spent an hour baking a cake from scratch.

I have made many mug cakes in my time, including experiments with different ingredients and ratios to find a perfect texture, and this one is hands down my favorite. It’s the perfect recipe to pair with any leftover candy from your trick or treating, and it only takes a minute to prepare in the microwave!

C’mon – You know you have lots of candy leftover from Halloween. Why not do something interesting with it?

These cakes are moist, not too dense, but not too light like a sponge cake. The melted butter and sour cream are key ingredients for developing flavor and texture in these cakes. My three favorite leftover Halloween candies to use and candy-coated chocolate pieces, peanut butter cups, and straight-up chocolate bars.

I usually have a main whisking bowl and spoon the batter over so I can really whisk it all together. You can make the mug cakes even easier by whisking the batter right in the cup you’re using for baking (instead of mixing in a separate bowl). It is hard to get an even consistency mixing with a fork inside the mug, but many mug recipes recommend this method to save one more bowl to wash. Either way, these will be a hit!

Let’s get cooking!

Get creative with your ice cream and candy filling combinations. Pair mint chocolate chip ice cream with leftover peppermint patties for chocolate mint mug cakes.
