Lime Mug Cake

This fluffy mug cake is scented with lime zest for a light and citrusy finish. It’s not too sweet and ready in less than five minutes.

I had a really fun weekend with some good friends visiting, but I didn’t have much time for baking. I couldn’t imagine ending the weekend without a baked good, so this 5 minute mug cake was the perfect solution.

Last week I had lunch with CC and she gifted me with some great food items, including a jar of lime curd. I immediately wanted to make a lime mug cake with it, much like my lemony mug cake.

I decided to mix it up a little, with this oversized wide-rimmed cup. It ended being the perfect size for this mug cake.

I also have an easy Lime Coconut Mug Cake that takes just minutes to make! Or, if you’re serving more people, try my Olive Oil Cake with Lime.

  1. it looks delish–i love lime!

  2. What a fun idea, love this!

  3. Oh yay! Now I know what to do with the lime curd!  My husband and daughter like sour desserts more than me so this is perfect! : )

    • i hope they like it! thanks again for the jar! i loved using the lime curd this way. and the lime zest makes it more lime-y flavored, giving it that slight tartness because the curd is pretty sweet
