Allulose is a rare sugar that tastes and behaves like sugar but is largely not metabolized by the body. It provides sweetness with minimal impact on blood glucose, making it a popular choice for low-carb, keto, and diabetic-friendly cooking.

How to Use Allulose

Allulose is a low-calorie sweetener that can replace sugar in many drinks, sauces, desserts, and baked goods. It provides about 70% of the sweetness of regular sugar, so an equal amount of allulose will taste less sweet.

Using Allulose as a Sugar Substitute

When sweetness is the main concern, start with about 1 1/3 cups of allulose for every 1 cup of sugar. You can adjust the amount to taste. Some packaged allulose products contain other sweeteners and may be designed to replace sugar 1:1, so check the package directions before using a larger amount.

Allulose works especially well in cookies, cakes, muffins, sauces, beverages, ice cream, and other recipes where sugar normally provides both sweetness and bulk. Unlike highly concentrated sweeteners such as stevia or pure monk fruit, allulose can provide some of the volume that sugar contributes to a recipe.

Baking with Allulose

Allulose browns more quickly than regular sugar and many other low-carb sweeteners. Baked goods made with allulose may become dark before the center is fully cooked. Check baked goods early and consider reducing the oven temperature slightly if excessive browning becomes a problem.

Allulose also helps baked goods retain moisture and can produce a softer texture. In frozen desserts, it can help reduce iciness and keep the finished dessert softer than some other alternative sweeteners.

Quick Tip: Watch color rather than relying only on the usual baking time. Allulose can brown rapidly, so a deeply browned surface does not necessarily mean the center is finished cooking.
