Use immediately to frost your favorite cakes or cupcakes.
Ermine frosting is best used on cakes that will be stored at room temperature or in the refrigerator.
Tips and Notes:
Cooling the Paste: Ensure the flour paste is completely cooled before adding it to the butter mixture. If the paste is too warm, it will melt the butter and the frosting will be soupy.
Room Temperature Butter: Your butter needs to be at room temperature, but not melted. It should be soft enough that you can easily make an indention with your finger.
Be Patient: The frosting might look curdled or separated at first, but don’t worry! Just keep beating it, and it will eventually come together into a smooth, fluffy frosting.
Not Too Sweet: Ermine frosting is known for being less sweet than traditional buttercream frostings. If you prefer a sweeter frosting, you can add more sugar, but do so gradually and taste as you go.
Storage: Store leftover frosting in an airtight container in the refrigerator for up to 3 days. Re-whip before using.
