To fix soupy Swiss Meringue Buttercream, place the bowl back over a double boiler, whisking until the mixture reaches 160°F. Then transfer it to a stand mixer and whip on high until stiff peaks form. If still runny, refrigerate for 15-20 minutes and re-whip. Ensure the butter is added at the right temperature—not too warm. This process stabilizes the buttercream, giving it the right texture.
