Key Lime Pie Sheet Cake

Today, I was at Old Navy. Gord and I had a mini morning date and so we went to breakfast and did a little shopping. Gord needed shorts {allegedly} and I needed everything in the store, so we went.

You guys. I got a romper…ok, technically a ‘jumpsuit’. And it is the most wonderful thing in the world. I didn’t realize how friggin’ comfy and roomy they are. Shelly first told me about her love for them in Sandestin and I’ve been meaning to get to a store to actually try one out.
Well, the stars aligned so I took it as a sign and tried it out and lo and behold, it was as glorious as I had hoped. Stretchy waistbands with ties! Loose pant legs! Lightweight fabric! So I got one.

I texted my husband a picture who was out in the store and he…..did not like it. Like at all. Actually his exact words were “Hey! Now when we play the newlywed game, I’ll have something to say when people ask what article of clothing your wife owns that you hate!” Yeah, thanks honey.

The whole ride home I googled ‘man romper’ and showed him the pictures…….and threatened to get him this one for Father’s Day.

I’m such a good wife.

I’ll keep you posted if I make any man romper purchases in the near future. 😉 LOL!!

Anyways, ever since I created this Peanut Butter Pie Sheet Cake I’ve been toying around with other flavors I could try…why it took me a few years to come around to making another one again, I’ll never know. But, you lucky souls get to behold the glory of my newest sheet cake creation….ode to key lime pie on a sheet cake.

I’ve had quite a few key lime pies over the years and there has only been one that I didn’t particularly enjoy…and it’s been so long ago that I can’t remember why I didn’t like it. We can all thank mom brain for that.

The point is, I love key lime pie so much that I’ve added it right on top of a sheet cake. It’s like the ultimate pie-cake love child that happens to feed a crowd.

Perfect for those family summer BBQ’s.

I may or may not be making several large sheet cakes for a big Brennan family reunion this July.

Anyways, this is a fun, easy, no hassle dessert that everyone will love! It’s just the right amount of sweet, tang, cake and cream! Although, you can never have too much whipped cream.

    I am not sure if it is just my browser or not but there are no directions on the Key Lime Pie Sheet Cake. The Ingredients list is there so I can probably guess but would like to make sure. I did click the printable recipe just in case but it is the same. Thanks for sharing your wonderful recipes!

      It was an html error that’s all fixed now! You should be able to print everything no problem now. Glad you enjoy the recipes, Linda!

    Linda – the same thing happened to me. I can see the directions, but when I try to print the recipe, the ingredients print, but not the directions.

    Sorry, but I have to agree with Gord. I was forced to wear one as a child and it was a nightmare when you had to go. I did the giant shirt with leggings too. I guess those are cool again.

    I was 8 months pregnant and living in a jumpsuit. On Mother’s Day my husband took me out to buy new clothes. I tried to explain to him that I was due soon and it was a waste of money. He didn’t care. He HATED the jumpsuit. Men are funny. Love this guy.

      I’ve never tried it in a 9×13 but I think it should work just fine…the layers will be twice as thick, but still super delicious 🙂

    Your Key Lime Sheet Cake looks delicious! Can you tell me the size of your jelly roll pan. I went to buy one and they are all different sizes. Thank you for this awesome recipe!!

    I’m having trouble getting the topping to thicken. I’ve been mixing for almost 10 minutes now & it’s still pretty thin. I followed the instructions perfectly.

    I made this for Easter and everyone enjoyed it. It is a fairly light dessert which was perfect after a big meal.

    FYI, my jelly roll pan is ~13×17 and the cake was done in 12 minutes if not a little sooner

    […] saw this Key Lime Pie Sheet Cake from Lauren’s Latest recently and was immediately intrigued. I am more of an orange girl […]

    Made this cake about a month or so ago, everyone liked it BUT said it was too bitter/sour tasting. I used just regular limes, I am making it again next week and will try some bottled key lime juice instead. Other than that it was very good.
