Prepare the ingredients per the instructions above.
Brew the coffee then refrigerate to cool.
In a medium saucepan, bring water to a boil.
Once boiling, stir in the rolled oats and a pinch of salt.
Reduce heat to medium-low and simmer for about 5 minutes, stirring occasionally, until oats are tender and the mixture thickens.
While the oats are cooking, prepare the apple. Peel, core, and dice it.
Add diced apple and cinnamon to the oatmeal mixture. Cook for an additional 2-3 minutes until the apple softens and incorporates with the oats.
Once the oatmeal is ready, divide it into bowls. Top each bowl of oatmeal with chopped nuts and drizzle with honey.
Pour the coffee over ice and prepare to your liking.
Enjoy your hearty and delicious apple cinnamon oatmeal alongside iced coffee.
