Lemon Curd Loaf Cake is the perfect afternoon treat. Serve with a cup of tea, you just can't beat lemon cake. This lemon cake is swirled with lemon curd all throughout for an extra tangy-sweet dessert! Use homemade or store-bought lemon curd!

Lately, lemons have been ruling my house. And you know what I don't hate it. I love lemon on just about anything, squeeze it on top of some soup, with salmon, in my tea, in a cake...you get it.

My mom has a lemon tree so I am lucky enough to have fresh lemons pretty much whenever I want. Last week I made my tart lemon curd recipe, the recipe makes a fair bit so I had leftovers, what to make I thought? So many ideas- Eton mess, lemon curd biscuits, cheesecake with lemon curd, lemon layer cake with lemon curd filling, then I decided on a lemon loaf cake that would be swirled with lemon curd.

I based the recipe loosely off of my wildly popular lemon and raspberry loaf cake. I love that in this lemon curd loaf cake you can see the swirls of the lemon curd. This was the perfect treat, my whole family loved it. I hope yours does too!

The texture of this lemon cake is thick, soft, and dense, this is not a light and airy cake, but that's what I love about it!

Bake It 'Til You Make It!

First things first, you need lemon curd, you can make your own but keep in mind it does need to chill in the fridge for a few hours or you can use store-bought.

Baking is a science and to really achieve the best results I highly recommend investing in a kitchen scale. This OXO Kitchen Scale is the one I use and is also the number one recommended kitchen scale by Cook's Illustrated. Think about it -what one person scoops into a "cup" is completely different from what someone else scoops!

Baking for success

Bake for 40 minutes then place a piece of foil on top to prevent the lemon curd from turning too dark, place back in the oven for an additional 20-30 minutes or until a toothpick inserted in the center of the cake comes out clean. Everyone's oven is different so I highly suggest checking the cake at a total of 55 minutes just in case your oven runs very warm.

While most everyone has had success with this recipe a few readers complained of an underbaked cake. So I recently made the cake again, at 30 minutes I added a lightly greased piece of foil on top of the cake to cover it and prevent it from browning too much. Then I let it cook for another 20 minutes, at this point the cake was perfectly done. I do find that doing less swirling to the outside edges of the cake helps prevent any super dark spots on the cake from the lemon curd.
