Your Italian meringue buttercream may be runny due to temperature issues. Ensure the meringue is cooled to room temperature before adding butter. If the mixture is too warm, the butter will melt, causing a runny texture. If it’s already runny, refrigerate the buttercream for 15-20 minutes and then re-whip until it firms up.
