How to Resoften Buttercream Frosting

By Elle Hanson

Buttercream frosting is created primarily using butter and sugar. A delicious confection, it stores well either in the refrigerator or freezer but becomes hardened after being chilled or frozen. Re-softening buttercream frosting, however, is simple and will not change the taste or texture.

Step 1

Allow frozen buttercream frosting to thaw in the refrigerator overnight. Test it with a butter knife, which should slide into the frosting fairly easily.

Step 2

Remove the frosting from the refrigerator and let it sit for couple hours until it reaches room temperature.

Step 3

Break the buttercream frosting into chunks and place them in a large microwave-safe bowl.

Step 4

Microwave the frosting at 10- to 15-second intervals until it begins to melt. Avoid allowing all of the frosting to melt.

Step 5

Use a whisk to whip the melted and solid frosting together until smooth and soft. If it does not soften as you beat it, return the frosting to the microwave for a few more seconds and try again.
