Vegans avoid using or consuming animal products. Many nonvegan recipes can be converted to vegan recipes with a few substitutions. In the case of powdered milk, there are several varieties of milk powder that may be viable options for vegans and people with certain food allergies.

Soy Milk Powder

Soy milk powder is soy milk with the water removed. Soy milk powder is white to beige in color and mixes well with both warm and cold water. It can be plain or flavored and may contain sugar and calcium. Soy milk powder is available in some mainstream grocers and online. It can even be found in bulk. Use soy milk powder to replace powdered milk in equal parts. Soy milk powder should be kept in the freezer or refrigerator.

Potato Milk Powder

Potato milk powder is a good option for people unable to tolerate soy or gluten. Available in both original and chocolate, potato milk powder is easy to find online. Use potato milk powder in a 1:1 ratio in place of powdered milk. People with a soy allergy should read the potato milk powder labels, as some brands contain soy.

Rice Milk Powder

Rice milk powder does not contain soy, gluten, dairy or lactose, making it a good substitute for those with food allergies or intolerances. Rice milk powder is available in some natural food stores and is found online. Use an equal amount of rice milk powder in recipes that call for milk powder.

Coconut Milk Powder

Coconut milk powder is significantly heavier than dairy milk powder and some brands contain as much as 70 percent oil. When using coconut milk powder for baking, the results will be heavier. Because of the high oil content, coconut milk powder is best suited for making different concentrations of coconut milk or used as a nondairy creamer. If you have a casein allergy or are lactose intolerant, read the labels on coconut milk powder, as some contain sodium caseinate.
