What changes the calories
- Sifting makes a big difference by volume: 1 cup unsifted weighs 120 g (467 calories), while 1 cup sifted weighs 100 g (389 calories).
- How tightly the sugar is packed into a spoon or cup changes how much you actually use.
- Mixing it into icing or glaze with butter, cream or milk adds the calories of those ingredients on top of the sugar.
- A light dusting over a dessert usually uses far less than a measured spoonful, so estimate the amount that actually ends up on your plate.
Tips for logging it accurately
- Weigh powdered sugar in grams when you can, since cup measurements vary a lot with sifting and packing.
- When logging by volume, pick the sifted or unsifted cup entry that matches how you measured.
- For frosting or glaze, log the butter, milk or cream separately, or log the whole recipe in BerryFit and divide by servings.
