Full Ingredients
Oatmeal Base
- 1 cup (240 ml) milk (whole milk makes the creamiest oatmeal, but any milk works)
- 1/2 cup (120 ml) water
- 1 cup (90 g) old-fashioned rolled oats
- 1/2 teaspoon ground cinnamon
- 1/8 teaspoon fine salt
Apple + Sweetener
- Choose one:
- 1 medium apple (about 180 g), cored and diced small (about 1 1/2 cups diced)
- 1/2 cup (120 g) unsweetened applesauce (stir in near the end)
- 1 tablespoon packed light brown sugar or 1 tablespoon (15 ml) maple syrup
Peanut Butter + Toppings
- 2 tablespoons (32 g) peanut butter (creamy recommended)
- 1/4 cup (30 g) walnuts, chopped
- 2 tablespoons (18 g) raisins
Step-by-Step Instructions
Step 1: Prep the apple (or measure applesauce)
If you’re using a fresh apple, core it and dice it small (about 1/4-inch pieces). Smaller dice soften quickly and distribute evenly through the oats.
You can peel the apple for a softer texture, or leave the peel on for a little more bite.
If you’re using applesauce instead, measure out 1/2 cup (120 g) and set it aside to stir in near the end so it keeps its fresh apple flavor.
Step 2: Warm the cooking liquid
In a small saucepan (2-quart works well), combine 1 cup (240 ml) milk and 1/2 cup (120 ml) water.
Set over medium heat and bring to a gentle simmer, stirring occasionally so the milk doesn’t scorch.
This should take about 3–5 minutes.
Step 3: Add oats, cinnamon, and salt
Stir in 1 cup (90 g) rolled oats, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt.
When the mixture returns to a gentle simmer, reduce the heat to low.
Step 4: Cook until creamy and tender
If using diced apple, stir it in now. Cook on low for 6–8 minutes, stirring often (every 30–60 seconds).
The oats should look creamy and the apple pieces should be tender.
If the oatmeal starts to thicken too quickly, add an extra splash of milk (1–3 tablespoons / 15–45 ml) and keep stirring.
Step 5: Sweeten and add peanut butter
Turn off the heat. Stir in 1 tablespoon brown sugar (or 1 tablespoon maple syrup) and 2 tablespoons peanut butter.
Stir until the peanut butter fully melts and the oatmeal looks glossy and thick.
Step 6: Stir in applesauce (if using) and adjust texture
If you’re using applesauce, stir in 1/2 cup (120 g) now.
Taste and adjust: add a pinch more cinnamon for extra warmth, or a small splash of milk if you want it looser and creamier.
Step 7: Serve and top
Divide the oatmeal between two bowls. Top each with a sprinkle of chopped walnuts and raisins.
Serve hot while the oats are creamy and the toppings are slightly softened from the warmth.
Pro Tips
- Stir often for creaminess: frequent stirring releases starches from the oats, making the texture extra creamy without needing more ingredients.
- Keep the heat low after adding oats: a gentle simmer prevents scorching and helps the milk stay sweet and smooth.
- Dice apples small: 1/4-inch pieces cook quickly and feel integrated rather than chunky.
- Add peanut butter off heat: it blends more smoothly and keeps a rich, roasted peanut flavor.
- Toast the walnuts (optional but great): toast in a dry skillet over medium heat for 3–4 minutes, stirring often, then add as a topping.
Variations
- Apple pie oatmeal: add 1/8 teaspoon ground nutmeg and a tiny pinch of ground cloves along with the cinnamon.
- Extra protein: stir in 1 tablespoon (10 g) ground flaxseed or 1 tablespoon (12 g) chia seeds with the oats (add an extra 2–4 tablespoons / 30–60 ml milk if it thickens too much).
- Different nut butter: swap peanut butter for almond butter or cashew butter; keep the same measurement (2 tablespoons / 32 g).
Storage & Make-Ahead
Store leftover oatmeal in an airtight container in the refrigerator for up to 3 days.
Reheat in the microwave or on the stovetop over low heat, adding 2–4 tablespoons (30–60 ml) milk to loosen it as it warms.
For quick mornings, pre-dice the apple the night before and store it tightly covered in the fridge. (If you want to reduce browning, toss the diced apple with 1 teaspoon lemon juice; this is optional and will add a faint brightness.)
