Sugar & Chocolate Calculators for Home Bakers and Sweet-Makers
Working with sugar and chocolate demands precision. Whether you are tempering chocolate for truffles, boiling sugar syrup to the soft ball stage, or calculating how much fondant you need to cover a tiered cake, getting the quantities and temperatures right is the difference between a professional finish and a sticky mess. Our sugar and chocolate calculators take the guesswork out of confectionery and cake decorating.
The chocolate tempering calculator provides precise temperature targets for dark, milk, and white chocolate, guiding you through the melt, cool, and working phases. The fondant coverage calculator uses your cake dimensions to work out exactly how much rolled fondant you need, while the buttercream calculator gives you butter and icing sugar quantities for filling and coating cakes of any size. For traditional sweet-making, the fudge, toffee, and marshmallow calculators scale classic recipes to your desired batch size.
If you are reducing sugar in your baking, the sugar to sweetener converter handles the maths for stevia, erythritol, honey, and other alternatives, accounting for their different sweetness intensities. The icing sugar glaze calculator lets you choose your desired consistency — from a thick coating to a thin drizzle — and gives you the precise sugar-to-liquid ratio. All calculations use metric measurements and UK product references.
