Place the remaining ingredients into a cupcake wrapper. Carefully place the cupcake wrapper in the jar on top of the oats. Cover with the lid tightly.
When you're ready to prepare the oats, carefully remove the cupcake wrapper from the jar. Place the oats in a microwave safe bowl and add water, and then microwave (according to the package directions - make sure you check this before you leave home!). Once the oatmeal is prepared, mix in the toppings and enjoy!
Notes
Have fun choosing which nuts, seeds, dried fruit, and other toppings you choose! I used various mixed nuts, golden raisins, and pepitas!
