Here is an easy birthday present when you are low on supplies. I got the recipe from here: How To Make Pancakes For One.
1 cup flour, 1 teaspoon baking powder, 1/2 tablespoon sugar, 1/4 teaspoon salt.
Combine these ingredients in a bowl, then pour them into a jar. Pack them down to make everything fit.
Make a label for the jar with what is inside (pancakes for one) and what to add (1 egg, 3/4 cup milk, 1 tablespoon butter).
