For the chia jam: Add the berries to a medium saucepan. (There’s no need to defrost if they’re frozen, although I usually let them sit on the counter for a few minutes so they are just soft enough to roughly chop. This makes the mashing easier when cooking, but it’s not critical.) Cover and bring to a simmer over medium heat, stirring frequently. Once the berries are warmed throughout and beginning to look saucy (about 5 minutes or so), mash them with a potato masher or dinner fork.
Stir in the sweetener and chia seeds and continue to cook, uncovered and stirring frequently, until the jam has thickened and reduced somewhat, about 5-10 minutes more. The jam will further thicken as it cools. Remove the pan from heat and add more sweetener if you’d like. (To help you gauge, I do think the jam tastes slightly sweeter once it has cooled.)
For the oatmeal: Melt the coconut oil or butter in a large skillet over medium heat. Add the oats and toast, stirring occasionally, until they start smelling fragrant and nutty, about 5-6 minutes. The oats may be toasted, cooled, and stored in an airtight container for approximately one week at room temperature or several weeks in the fridge.
In a medium, heavy bottomed pot, combine the water, milk, salt, and optional spices. Bring the mixture to a slow boil over medium heat. As soon as the mixture is simmering evenly across the surface, add the oats and stir to incorporate them into the liquid. Cover the pot and turn off the heat. Let the oats sit on the burner, untouched, for 7-9 minutes. After 7 minutes, uncover and check the oats. The liquid should be almost completely absorbed and the oats tender. If you still have some excess liquid, replace the lid and allow the oats to continue to absorb the liquid for a few more minutes.
Portion the oatmeal into bowls and top with a generous helping of the chia jam, melted peanut butter or peanut butter powder syrup**, and any additional toppings of choice. Mix it all together and enjoy!
