Key Lime Pound Cake with a sweet vanilla glaze

I’ve been getting so many request for a homemade key lime pound cake! I think that the recipe request started pouring in since the beginning of summer 2016. Must admit, that I had to play around with a few recipes, before I could bring you the perfect key lime pound cake. Some of the recipe for this cake we’re kind of “blah”, some we’re good, but I was looking for spectacular. I think one of the best recipes that I tried (before this one anyway) was southern livings key lime pound cake. Although I loved the recipe, I decided to switch out, and add some ingredients to make the perfect key lime cake recipe.

This light and moist key lime pound cake is a sinfully sweet dessert

This pound cake is made from scratch. This is not a key lime bundt cake with lime jello. Yeah, it sounds good, but we’re going skip out on the gelatin. For now anyway….

    Hi Rosie! I adore key lime and your recipe showed up just in time for me to make and bring it to a Super Bowl party. It was a hit – even with my 18-month-old niece! She sat right up in her highchair and was stuffing her face with little cubes of it. The cake was moist and delicious and came out of the pan very nicely. I will definitely make this again – 5 stars all the way! Thank you for another great recipe.

  7. My family loves key lime anything. I a going to try this recipe but make it gluten free with a cup-4-cup gluten free flour. This is so exciting. Thank you for sharing. It all looks so wonderful. Didn’t know where to start til I saw this recipe. I’m just south of Seattle. It’s a nice place to live.

    This cake is very, very good. One of the best pound cakes in my cake files. I am a serious baker that sells homemade cakes, cookies and tea cakes.
    I did not deviate from the recipe, but I could barely taste the key lime. I wanted a more intense key lime flavor so the following day I made a syrup of key lime juice and sugar, punched holes all over the cake and poured it over the cake. I also brushed the bottom of the cake and the sides of the cake with the syrup.
    Now it has the same flavor as a key lime pie. Wow! To die for.
    Thanks for this wonderful recipe.
