How to Store Buttermilk Cake

When you make this cake, you will to make sure you have stored the cake correctly to make it last the longest. The most important thing when you store buttermilk sheet cake is to make sure it is not left uncovered. The air will make this cake get stale faster. Store the cake wrapped in plastic or in an airtight container. The cake can be kept at room temperature for about 4 days. If you do not think you can eat all the cake before it starts to spoil, move it to the freezer right away.

Can I freeze this sheet cake recipe?

Whenever you make a sheet cake, there are several ways to freeze it. Normally I make the cake and we have it for about 2 days. Then, I will cut the rest of the cake into slices. First I put the cake on a plate or baking sheet in the freezer to freeze. Once it is frozen, I move it to freezer bags. I like to freeze the cake first because that way the frosting does not stick to the freezer bag. When it is time to thaw the cake, you will want to take it out of the freezer bag first. Otherwise, the frosting will stick as the cake thaws.

You can also make the cake and as soon as it cools, you can freeze the cake as a whole. This is before adding the frosting. This is a great way to have the cake when you want it but do not have to worry about the frosting.

Do I have to use fresh lemon for this best lemon cake recipe?

While fresh lemon juice is the better choice for the best lemon cake recipe, you can use lemon concentrate in its place. There are many types of lemon concentrate that is available. Look for a lemon juice that is pure lemon without any added things to it. Whenever possible, use fresh lemon juice directly from the lemon.

Ingredients for homemade lemon cake

  • cake flour
  • baking powder
  • baking soda
  • salt
  • buttermilk
  • lemons
  • vanilla extract
  • granulated sugar
  • unsalted butter
  • eggs
  • confectioners’ sugar

How to make lemon sheet cake

Preheat the oven to 325°. Grease a 9×13 inch square baking pan and set aside.

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt; set aside.

Combine buttermilk, lemon juice, and vanilla in liquid measuring cup.

In the bowl of a stand mixer beat granulated sugar and lemon zest until moist and fragrant, about 1 minute. Transfer 1/4 cup of the sugar mixture to small bowl, cover, and set aside. Add butter to the remaining sugar mixture and beat until light and fluffy, about 2 minutes. Beat in eggs and yolk, one at a time, until combined. Reduce speed to low. Add flour mixture in 3 additions, alternating with 2 additions of buttermilk mixture, and mix until smooth, about 30 seconds.

Pour batter into prepared pan and smooth top with an offset spatula. Bake until cake is golden brown and toothpick inserted into center comes out with a few moist crumbs attached, 25 to 35 minutes. Transfer cake to wire rack and let cool 10 minutes.

To Make the glaze: In a medium bowl whisk confectioners’ sugar, lemon juice, and buttermilk until smooth. Using an offset spatula, spread glaze over warm cake and sprinkle evenly with the reserved sugar mixture. Cool completely, at least 2 hours. Serve.
