  • 2/3 cup old fashioned oats
  • 1 1/3 cups water (or use milk for creamier oatmeal)
  • 2 teaspoons instant coffee (use regular or decaf)
  • 1 teaspoon cinnamon
  • 2 tablespoons sugar or equivalent amount of sweetener (use more or less, according to your tastes)


  • Combine all ingredients in a large microwaveable bowl.
  • Microwave on high for 2 minutes. Watch carefully during the whole cooking process in case the oatmeal starts to boil over.
  • Stir, and microwave for another minute.
  • Stir, and microwave for another minute.
  • Test the oatmeal for thickness. If you would like it a little thicker, keep microwaving at 30 second intervals.
  • Oatmeal will also thicken a bit upon standing.


  • Be careful, the bowl will get very hot!
  • Use almond milk, or your favorite non-dairy milk, for creamy oatmeal without the dairy.
  • You can substitute honey or another natural sweetener for the sugar.
  • If this method is too tedious for you, try this:
    • Use a very large microwaveable bowl, to allow to the oatmeal to boil up a bit.
    • Microwave on high for 2 minutes, stir.
    • Microwave on 30% power for 4 minutes, stir.
    • If the oatmeal is still too thin, microwave on 30% power for another 1-2 minutes.
  • Add a little cocoa if you want more of a mocha experience.
