More invert sugar than the recipe calls for
I am making sugarlogie's american buttercream. The recipe for 1 cup of butter cream only calls for 3 1/2 tbsp of sugar syrup. I chose invert syrup because it's the sweetest of the options she provided. I didn't want to have excess syrup so I did 62 grams of sugar, 1/4 of cream of tarter, and 30 grams of water. Can I use my entire recipes worth of syrup in the buttercream and just reduce the powdered sugar? I wanted a recipe with sugar syrup specifically because I'm using it for ice cream
