The best frostings to stand up in the heat are fondant frosting and royal frosting.
The frosting of a poptarts is mostly refined sugar. "Dry" sugar melts at a higher temperature than "wet" sugar (wet like regular cake frosting with water and fat mixed in). Poptarts frosting is more likely to burn before melting, but it will eventually melt given enough heat and enough time.
If you frost a hot cake, the heat from the cake will melt your frosting. You should allow the cake to cool completely before frosting. Cake is delicious warm; if you aren't planning on frosting it, it's perfectly fine to serve the cake before it cools. Allowing a cake to sit and cool for a bit also helps the cake to hold together better.
when u frost a warm cake, the cake absorbs the icing making the icing soak into the cake which will make your cake nasty and stiff...
Buttercream frosting is made by combining a fat (butter or shortening) with sugar; both fat and sugar tend to soften and eventually melt in warm weather. Any buttercream frosting will melt if left in a warm room or outside in the sun in warm weather.
no sorry you have to make a glaze
it depends on what kind of frosing you use and the tempuriture.
because the frosting will melt if you dont
Well, sweetheart, that frosting on a pop-tart is tougher than it looks. It's designed to withstand the heat of the toaster without turning into a gooey mess. So, while the pastry gets all nice and toasty, that frosting stays put like a champ. Just like a good pair of Spanx, it's all about that heat resistance, honey.
Because if you use things like : Cake frosting, whip cream ect.. They'll melt and drip off.
yes, just put it in the microwave on low for 30 seconds
depends on the heat but usually it will melt
To correctly answer this I would need to see the recipe. But many frosting recipes require you to only soften the butter and never to melt it. In order to have a frosting turn out thick the butter needs to be softened. If it's melted it won't properly combine with the other ingredients.
