Key Lime Bundt Cake is delicious! This recipe made with a box of cake mix and a package of instant pudding. It’s a mixture of tangy citrus and soft, sweet cake.

I’m a fan of anything with key lime. It’s like taking a big bite of spring and summer. If you’re a fan, too, I betcha you’ll go nuts for these mouthwatering Key Lime Bars. If you’re in a big hurry, whip up a sweet Key Lime Cheesecake Dip. You never have to wonder what you’re taking to pot luck when you have the ingredients for these treats.

Key Lime Bundt Cake

Key Lime Bundt Cake

Did you know that key limes are somewhat different than regular limes? Key limes have a stronger smell, they are a bit more tart, and they don’t have as much juice as regular limes.

When I am using key limes in a recipe, I first microwave them to make them softer so I can more easily extract the juice. Pop them in for about 30 seconds or so and then roll them around on the counter using even pressure from your hands.

Juicing a key lime is not easy. I’m not going to lie to you. What doesn’t work well is to use your hands to try and squeeze the juice out of them. It’s too hard!

You can definitely buy the juice so that you don’t have to try and work with the limes. There is no shame in that game. But, like most things, the “real” tastes better than the stuff you get in the bottle. (That’s just my opinion.)

Once you’ve microwaved and rolled, cut it in half and use a fork to juice it. Stick the fork in the lime and twist, twist, twist over a bowl. You’ll get some pulp, but that can be easily removed. I’d pick up 6 or 7  key limes to get the right amount of juice for this recipe, although depending on the fruit you pick, you might need more.

And yes, you can buy regular limes that are a little bit easier to work with and use those. It’ll taste a smidge less flavorful, but you can be the judge as to whether you mind that trade-off.

Cream Cheese Frosting

There is no way I can even mention cream cheese frosting without telling you how much I love it! I am such a cream cheese fan, it’s ridiculous. Are you?

Before you make this recipe, take the cream cheese out of the refrigerator and let it sit until it’s softer. Hard, cold cream cheese won’t work.

    I’ve now made this twice and both times it’s been a hit.

    The flavor was great! I’m curious, how would this be adjusted to bake in a convection oven?

    OMG….it is delicious! I didn’t use key lime juice, I used the bottle of Key West Lime juice, and I put a lemon glaze on top. Everyone raved how moist and tasty it was! I will definitely make it again!

    This was super easy to make and wildly delicious! I left out the green food coloring because I’ve never had a key lime pie or tart that was actually green and sometimes food coloring leaves an aftertaste.

    I used this recipe and made a layer cake! Awesome recipe! I made home made whipped topping with lemon extract for the icing and it turned out great!

  6. Charley says:

    Does these need to be kept in the refrigerator or can it be left on a covered cake plate?

  7. Linda says:

    can this cake be made ahead and freeze?  Without the frosting of course!

    1. Jill says:

      Sure! Wrap it in plastic wrap first and then with foil.

    Your key lime bundt is the best! My husband asked me to bake one for my own birthday!!! Everyone loves it! Thanks.

     My sister loves anything key lime, I’ll make this for her birthday next week. 2 questions-can I substitute olive oil for the canola? And am I supposed to make the pudding or just use it dry? Also the final ingredient listed says “9 inch bundt cake” …

      Don’t make the pudding just add the package with sugar to the cake mix, whisk together then make a well. Add all the wet ingredients then mix well. We thought this was so good we didn’t even frost it!
