Simmer the base: In a small saucepan, combine 1 cup milk (or half milk/half water), 1/2 cup rolled oats, and a pinch of salt. Bring to a gentle simmer over medium heat, stirring occasionally so it doesn’t stick.
Add the cherries: Stir in 1/2 to 3/4 cup pitted cherries.
If using frozen, add them straight from the freezer. Cook 3–4 minutes, until the oats soften and the cherries release a little juice.
Thicken and flavor: Reduce heat to low. Continue cooking until the oats are creamy, about 2–3 more minutes.
Stir in 1/2 to 1 teaspoon vanilla extract.
Incorporate the protein: Remove the pan from the heat. Whisk 1 scoop vanilla protein powder with a splash of milk in a small cup to make a smooth slurry. Stir the slurry into the oatmeal until fully combined.
Add a touch more milk if too thick.
Sweeten to taste: Taste and add 1–2 teaspoons maple syrup or your preferred sweetener if needed. The cherries might already provide enough sweetness.
Serve and top: Spoon into a bowl. Finish with your favorite toppings—crunchy nuts for texture, Greek yogurt for extra protein, or cacao nibs if you like a chocolate-cherry vibe.
