Coconut Cake with Lime Curd and Coconut Buttercream

A secret ingredient of sour cream makes this cake so moist, dense, and delicious!

Cook:

25 mins

Yield:

2 – 9 inch round cakes

Ingredients

·      1 (18.25 ounce) package white cake mix

·      1 cup al purpose flour

·      1 cup white sugar

·      ¾ tsp salt

·      1 1/3 cups water

·      1 cup sour cream

·      2 tbl vegetable oil

·      2 tsp coconut extract

·      2 eggs

Directions

Preheat oven to 325 degrees F (165 degrees C). Grease and flour an 11x13 inch cake pan.

Stir together the white cake mix, flour, sugar, and salt in a large bowl until well mixed. Pour in the water, sour cream, vegetable oil, almond and vanilla extracts, and egg whites, and beat with an electric mix on low until all the ingredients are mixed and moistened but some lumps still remain, 4 minutes.

Pour the batter into the prepared cake pan, and bake in the preheated oven until the top is a light golden brown and a toothpick inserted into the center of the cake comes out clean, about 25 minutes. Allow to cool before frosting.

Lime Curd

Use limes, key lime juice, or even lemon to make the perfect curd at home. This recipe is easy and is done in under 10 minutes!

Ingredients

·         3 large eggs

·         3/4 cup granulated sugar

·         Pinch of salt

·         1/2 cup fresh lime juice or bottled Key Lime juice

·         Zest of 1 large or two small limes or Key limes

·         4 tablespoons unsalted butter diced

Instructions

1.                   Place eggs, sugar, salt, juice, and zest in a medium saucepan. Do not put it over the heat yet. Whisk the ingredients together until smooth.

2.                   Place over low heat. Stir constantly with a wooden spoon until the mixture thickens, about 4-5 minutes. Turn all the way to low and add the butter. Stir until smooth.

3.                   Remove from heat and pour into jar(s). Makes just shy of 2 cups.

Coconut Buttercream

1 cup unsalted butter at room temperature

½ cup coconut milk

4 cups powdered sugar

½ tsp vanilla extract

1-2 tsp coconut extract

1/8 tsp salt

In the bowl of a stand mixer fitted with the paddle attachment, beat together the butter and coconut milk on medium speed until smooth, about 2 minutes.  Add the powdered sugar, vanilla and coconut extracts, and salt, raise the speed to medium-high and beat until combined, about 1 minute, stopping the mixer to scrape down the sides of the bowl as needed.  Cover and refrigerate until ready to use.  I added more powdered sugar to make it easier to pipe.

Assemble the Cake

Pipe buttercream around the round cake edge, fill in with lime curd.  Add second layer and frost the cake.  I put shredded coconut around the sides and then flaked toasted coconut on top. 

I doubled the recipes and made 4 layers, it was very tall.  I would suggest a 3 layer cake and make the rest into cupcakes or single layer cake.
