Key Lime Cake with Key Lime Cream Cheese Frosting

Citrus makes me think of Spring. This cake makes a great springtime dessert. St Patrick’s Day, Easter, and Mother’s Day would be the ideal time to enjoy this cake.

One of my favorite things to do is take an extensive recipe and make it easier to prepare. (You know how impatient I am!) I would love to spend hours in the kitchen baking and decorating cakes, prepping and preparing beautiful meals. But, the truth is, I just don’t have that kind of time. My boys have activities and need help with homework and such. I did implement a chore system for them to follow this summer, but they still need supervision. Therefore, for now, it’s simple, easy, and quick dishes!! (Mostly)

Tips and Method

This recipe was inspired by Trisha Yearwood’s Key Lime Cake, but I made it easier! I started with a cake mix with additions that make it taste homemade. The Key Lime Cream Cheese Frosting is completely from scratch.

Pour the batter into the pan, then bake until the cake sets. You’ll know it’s baked when a toothpick inserted in the center comes out clean, or with a few moist crumbs.

I was planning to give the key lime cake away, so I baked it in a disposable aluminum pan.

When I originally made this lime cake for my site, I made at in a 9×13-inch aluminum pan. I made it again for a celebration and made three 8-inch round layers. For both cakes, I topped them with a Key Lime Cream Cheese Frosting (recipe given below)!

How to frost a layer cake

Tip #1: Begin by ensuring your cakes are level; if they’ve domed during baking, trim the tops with a serrated knife or a cake leveler. If they’ve caved, no need to level them; simply fill the cavity with frosting.

Place the first cake on a cake board or plate using a cake lifter, then place the plate on a cake turntable. Add approximately 1/2 cup of frosting. Use an angled spatula to spread it evenly.

Tip #2: Evenly measure the frosting for each layer. Spread the frosting evenly over each layer, pushing any excess towards the edges.

Continue stacking the layers, ensuring equal portions of frosting between them. If it’s the final layer, place it with the flat side up and add about 1/2 cup of frosting on top. Smooth it evenly, and then apply a thin crumb coat of frosting to the sides.

Chill the cake for at least 30 minutes to set the crumb coat. Afterward, spread another 1/2 cup of frosting on top and frost the sides with a thick coat. Use a cake knife to smooth the sides, and then apply the same technique to smooth the top.

Tip #3: For easier smoothing, frost the cake with a thick layer of frosting. Following these steps will give you a clean canvas for your cake decorating endeavors.
