[header] How to frost a cake [title] Let your cake cool. [step] The biggest mistake you can make when frosting your cake is using a hot cake and cold frosting. If your cake is even slightly warm, it will melt the icing which will then run over the edges and soak into the top layer, making it soggy. <sep> (A) If you've got excess cold frosting you could try placing it into a cooler another time. If you really like cold cake mix, it will stay cooler. (B) Further, if you use cold frosting it won't be smooth enough to spread and will bring up a lot of crumbs. [substeps] Always wait for both your cake and your frosting to reach room temperature. (C) Let it cool on a cooling rack or on the counter until it's completely cooled, which should be 3 to 4 minutes. [substeps] You can either leave it on the refrigerator for a little while, or put it in the freezer. (D) The best temperature to frost the cake is in the early morning hours. Use a thermometer to gauge the cooling time before freezing.
