I’m in love with this new lemon mug cake I recently made.

I posted a lemon mug cake recipe last year after receiving multiple requests for a lemon flavored mug cake. While it tasted satisfactory, I always felt like there was room for improvement, so I’ve been trying to make a better version ever since.

My biggest struggle was trying to recreate the lemony flavor without having the cake end up tasting like lemonade. After about a dozen attempts, I finally had a breakthrough.

Just adding lemon juice and lemon zest wasn’t enough. I needed something more concentrated. Like lemon curd. I was able to find some in the jam section of my local grocery store. It’s concentrated, it’s sweet, and adding a heaping spoonful of it to the cake batter gave it that lemony taste I was desperately searching for.

I loved how this cake came out. So light and fluffy and lemony.
