One of the best ways I know to use malted milk powder is Malted Milk Pancakes. To be honest, we don't eat pancakes very often, but when we do I try to make them special and this is just one way (outside of blueberries, chocolate chips, etc).
The malted milk powder makes them a little lighter, adds malty flavor and a tiny touch of sweetness.
Freezing Malted Milk Pancakes
You can cut the recipe in half if you want a small batch, but an even better option is to make all the pancakes, stack them between sheets of parchment paper, put them in a freezer bag and freeze them. The night before, put the pancakes in the refrigerator too thaw, then just warm them in the microwave for a few seconds.
Here's a link to the recipe -- King Arthur Flour's Simply Perfect Pancakes.
