A delightful creamy, tangy frosting that goes so well with the flavours of sweet potato and five spice muffins.
Dextrose powder is known as glucose powder. Glucose powder is what's left from the sugar after you take out the fructose. It's suitable in small quantities for people with fructose malabsorption. You can buy it in any good health food shop or in the Home Brewing section of your supermarket.
If you are not following low fructose or fodmaps diet than you could replace the dextrose powder with regular icing sugar.
