In a large bowl, mix the bread flour, sugar, milk powder, and salt until combined. Carefully pour into a one-quart jar with screw top lid.
Put the yeast in a very small zip-top plastic bag and set it on top of the flour mixture inside the jar. Screw the lid on tight. Label and store in a cool, dry place until ready to bake.
When you're ready to bake the bread, pour the warm water and vegetable oil in the bottom of the bread pan of your bread machine. Place the dry ingredients from the jar on top of the wet ingredients, reserving the yeast for last. Follow the directions from your bread machine manufacturer when adding the yeast. Select white/light crust color on your bread machine.
Remove the finished bread from the pan after the baking cycle is complete and cool on a wire rack for 1 hour before slicing.
