Key Lime Pound Cake-a nice change up from the same old lemon!

So who gets all green for St. Patty’s Day? Honestly, I’m really not that into the holiday. When we were kids it was fun to go around pinching people who forgot to wear green but otherwise…it’s just another day. There is a big bonus to the holiday and that the food. I love any excuse to eat special food, especially sweets so I was all in when Jen from Jen’s Favorite Cookies invited me to participate in a St. Patty’s post.

We have this little cupcake bakery here in town. They make the most unbelievable Key Lime Cupcakes. I’d eat them by the dozen if I could afford to. Sadly, the bakery has overhead, blah, blah, blah and one cupcake is about $2.50. Two cupcakes for $5.00, sorry, no way. And they’re tiny. The cake part doesn’t even fill up the paper wrapper. I’m glad they’re doing well, I do try to support local, I’m just not going to shell out the bucks for something I can make myself.

I’m still trying to replicate their cupcakes but I did come up with this fantastic Pound Cake. The flavor is almost identical to those sweet little cupcakes. The cake is just denser, definitely a pound cake. I even found real Key Lime Juice at the store so I didn’t have to squeeze harm any Key Limes in the making of this cake.

Be sure to check out all the other wonderful recipes my friends have made for St. Patty’s.

  1. I feel the same as you, those cupcake shops charge a lot for a little cupcake and you can make something even better at home. Your cake is such a pretty green color. It has me looking forward to St. Pat’s and spring even more.

  2. ha! I love your comment about harming any key limes ;) There’s a few cupcake places here in Philly that make delicious cupcakes, but most of them are $4/cupcake! Granted, some of them have fancy flavors, but I feel like I’m paying for a ton of frosting and I don’t even like a lot on my cupcakes to begin with! /endrant. Anyway, this is a gorgeous poundcake and I’m sure it would also translate beautifully to cupcakes! Happy St. Patrick’s Day!

  3. Most cupcake places around us are at least $4 a cupcake too. Insane amount for one cupcake that I can make at home too!!! This is such a fun cake! I love how bright green it is!!!

  4. Sounds absolutely delicious and I just love the color! :)

  5. I’d rather have these in poundcake form anyways…that way I don’t have measured portions. :D

  6. I grabbed a bottle of key lime juice as a total impulse buy the other day. Obviously, this was the universe’s way of telling me that I should make this cake. (Well, either that, or the universe wants me to make key lime margaritas… I’m still trying to sort that out.)

  7. I’m glad no key limes were harmed in the making of this cake! I’m with Jen, I love pound cake, this looks really delicious.

  8. It looks great! I love lime flavored desserts, so I’ll sure love this one!

  10. Yum, key lime pound cake sounds absolutely delicious!

  11. Joan, I hear ya, girl. I never buy cupcakes because they’re always overpriced and they have more sugar laden frosting than the cake portion. I’d much rather bake them myself! Good luck on replicating the cupcake. In the meantime, this pound cake looks divine! I loooooove pound cake and this looks perfectly moist, dense and flavourful. Not to mention that amazing green colour – so festive!

  12. Oh my goodness …I love Key Lime Cake Joan! This is definitely on my “to-do” list

  13. I know, $5 dollars for a cupcake? Pu-lease. They cost like 60cents each to make.

    This is a PERFECT st. patty’s day treat! Yum!

  14. This is spectacular lady. I love a good pound cake and key lime is perfect for St Patty’s Day. Green is good. Bring on the green.

    I swear I’m a sucker for the tiny little cupcakes with coloured sprinkles at the grocery store. I don’t know why but I occasionally indulge. It’s hard to say no. Now Starbucks, whole different story. I once paid $6 for a cupcake and it wasn’t that good.

  15. This is perfect for St. Patty’s! I love the key lime!

  20. This looks great! Perfect for any time of the year not just St. Patricks Day! Thanks for sharing:)

  21. I totally agree with the whole “Not gonna pay that much when I can make a cupcake just as good” philosophy. One, OK. Because I like to support local, too. This is pretty amazing-looking pound cake!

  35. Love, love key lime! Adding it to a pound cake is genius!

  36. Ok, I made this wonderful looking cake yesterday and sadly it is very dry and not much flavor except for the frosting. Was there supposed to be a little oil in it or something? It looked beautiful and smelled really good while it was baking. I followed the recipe to the T. Any suggestions?

  37. Hey Joan! This looks so yummy! I am obsessed with lime anything! I would love for you to share this & any other recipes at my link party:
