How To Make A Layer Cake

This is one of the most impressive cakes I’ve tried, and I think you’re going to love it as much as I do. It’s flavorful, moist, fluffy, and begging you to devour it! Take a look at these simple steps to make this multi-layer cake. 

First Step: Put the oven rack in the center of the oven and preheat it to 350 degrees F. Use nonstick cooking spray and lightly spray the bottom of two 9-inch pans. Use parchment paper to line the bottom of the pan and spray it with cooking spray. 

Second Step: Using a medium bowl, combine the flour, salt, baking powder, and baking soda together. Set aside. 

Third Step: Combine the buttermilk, rum, vanilla, and lemon juice in a small bowl using a whisk. 

Fourth Step: Using a stand mixer and paddle attachment combine the butter and sugar. It should be fluffy and well blended. It will take around 3 minutes. Put the eggs and egg yolk one at a time and beat until it’s combined. Slowly pour in one-third of the flour mixture and beat on medium-low speed. 

NOTE: Don’t overmix the batter or the cake will become dense. Just beat for 30 seconds or so. 

Fifth Step: Pour in half the buttermilk mixture and beat for 30 seconds. Scrape the bowl as needed. Add half of the remaining flour mixture, buttermilk, and mix together. Finally, add the rest of the flour and mix. 

Sixth Step: Pour the vanilla layer cake batter into the prepared pans and bake for 25 minutes. A toothpick should come out clean when inserted in the center of the cake. Cool the rum cakes for 10 minutes, then turn the pan over and place the cakes on a cooling rack. Let the cake layers sit for a least 2 hours. 

Seventh Step: After the cakes have cooled, use a serrated knife to cut the tops off and make them level. 

Eighth Step: Begin making the rum soak as the cake has cooled. Using a small saucepan, bring the granulated sugar, rum, and water to a boil, then simmer over medium-low heat until the sugar has dissolved all the way. This takes around 2 minutes. Whisk in the butter until smooth.

Ninth Step: Take a fork and poke holes in each layer of the cake all over. Brush the cake layers with rum syrup and allow it to soak for at least 30 minutes. Then add frosting. 

Tenth Step: Prepare the frosting by adding butter to a stand mixer and beating with the paddle attachment. Once it’s fluffy, add the confectioner’s sugar, coconut rum, and vanilla and continue mixing until it’s light and fluffy. Place in the fridge until you are ready to frost this layer cake recipe. 

Eleventh Step: Place one layer of cake out and put 1 1/2 cups of the coconut frosting on top. Spread it out, so it’s even. Next, add the second layer of cake on top of the first. Place the remaining frosting on the top and sides of the cake. 

That’s all you need to do to make this double layer cake. I promise it’s worth every second of effort you put into it.  Now you can serve and enjoy!

How Many Pieces Of Cake Do You Get With This Layer Cake Recipe?

Every cake you make can be cut into different sized pieces. My intention with this easy layer cake is to cut it into 12 pieces. Because the rum cake recipe is pretty rich with butter, sugar, and rum, the pieces don’t need to be huge to enjoy it. 

What Is The Difference Between Light And Dark Rum?

Typically, when you bake, you want to use dark rum instead of light rum because it’s aged longer. This can make it a darker color, and it just tastes better in baked goods.

If you don’t have dark rum on hand and only have light rum, you can still bake this amazing cake recipe! Simply replace the white sugar with brown sugar. This will give you the same effect of using dark rum. 

How Do You Store This Layer Cake Recipe?

It’s best to store this layer cake recipe in the refrigerator for up to one week. You could also keep it on the counter if that works better for you, but the double layer cake will only last about 3 days at room temperature. No matter how you store it, it’s important to keep this rum cake recipe wrapped and airtight, so it doesn’t go bad.

Can You Freeze This Double Layer Cake?

Yes, absolutely, you can freeze this double layer cake! It’s easy to do. Just wrap each piece in plastic wrap and place them in a freezer bag. Or wrap up the entire cake and freeze in an airtight container. This layer cake recipe will last up to 3 months in the freezer, so it’s perfect for meal planning and a quick snack idea.
