- 1 tbsp (14 g) unsalted butter
- 1 tbsp (12–13 g) packed light brown sugar

- 1 cup (90 g) old-fashioned rolled oats
- 1 1/2 cups (360 ml) milk (2% dairy milk recommended for creaminess; or unsweetened almond/oat/soy milk)
- 1/2 cup (120 ml) water
- 1 tbsp (12–13 g) packed light brown sugar
- 1/2 tsp ground cinnamon
- 1/8 tsp fine salt

To Serve (Optional, but Delicious)
- 2 tbsp (14 g) chopped toasted pecans or walnuts
- Extra brown sugar, to taste (start with 1 tsp per bowl)
- A small pat of butter (about 1 tsp / 5 g) per bowl
- A splash of milk, as needed to loosen oatmeal

Step-by-Step Instructions
Step 1: Prep the apple and set up your pans
Core 1 medium apple and dice it into 1/2-inch pieces so it cooks quickly and evenly. Gather a small skillet (8–10 inches) for the apples and a small saucepan for the oats.
If you like nuts on top, you can chop 2 tablespoons (14 g) pecans or walnuts now.
Step 2: Sauté the apples in butter
Place a small skillet over medium heat (burner level 5/10) and melt 1 tablespoon (14 g) unsalted butter.
Add the diced apple and cook for 3 minutes, stirring once or twice, until the edges start to soften.
Step 3: Add brown sugar and cinnamon, and cook until glossy
Stir in 1 tablespoon packed light brown sugar, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt. Continue cooking over medium heat for 3 to 4 minutes, stirring frequently, until the apples are tender and coated in a shiny, cinnamon-brown glaze.
If the pan looks dry or the sugar starts sticking, splash in 1 to 2 tablespoons water to loosen it. Turn off the heat and stir in 1 teaspoon lemon juice (optional) to brighten the flavor. Cover to keep warm.
Step 4: Bring the oatmeal liquid to a gentle simmer
In a small saucepan, combine 1 1/2 cups (360 ml) milk and 1/2 cup (120 ml) water. Place over medium heat (burner level 5/10) and bring to a gentle simmer (small bubbles around the edges), about 3 minutes.
Step 5: Cook the oats until creamy
Stir in 1 cup (90 g) rolled oats, 1 tablespoon brown sugar, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt.
Reduce heat to medium-low (burner level 3/10) and cook for 5 to 6 minutes, stirring often, until the oats are tender and the texture is creamy. If it thickens too quickly, add an extra 1 to 3 tablespoons milk to loosen it.
Step 6: Rest the oatmeal for extra creaminess
Turn off the heat and let the oatmeal sit for 2 minutes to finish thickening. Stir in 1/2 teaspoon vanilla extract if using. Taste and add a tiny pinch of salt or an extra teaspoon of brown sugar if you want it sweeter.
Step 7: Assemble and serve
Divide the oatmeal between 2 bowls. Spoon the warm cinnamon apples over the top, making sure to scrape any buttery brown-sugar glaze from the skillet.
Finish with optional chopped nuts, an extra sprinkle of brown sugar, and (if you love a classic diner-style bowl) a small pat of butter melting into the oats. Serve immediately while hot.
Pro Tips
- For the creamiest oats: Stir frequently during the last 2 minutes of cooking to release starches and create a silkier texture.
- Keep apples tender, not mushy: Dice to 1/2-inch and cook just until they yield when pressed—about 6–7 minutes total.
- Balance sweetness: The pinch of salt and optional lemon juice make the brown sugar taste deeper and less one-note.
- Prevent sticking: Use a nonstick skillet for the apples or add 1–2 tablespoons water if the sugar tightens up.
- Want extra warmth: Add 1/8 teaspoon ground nutmeg or a pinch of ground cloves to the apples.
Variations
- Apple pie oatmeal: Add 1 tablespoon (8 g) raisins while the oats simmer, and finish with a pinch of nutmeg and extra toasted nuts.
- Maple-cinnamon version: Replace the brown sugar in the oats with 1 1/2 tablespoons (30 g) pure maple syrup; keep brown sugar on the apples for caramel notes.
- Protein-boost: Stir 2 tablespoons (32 g) peanut butter into the finished oats, or top with 1/2 cup (120 g) Greek yogurt (served on the side or swirled in).
Storage & Make-Ahead
For best texture, store the oatmeal and apples in separate airtight containers in the refrigerator for up to 4 days. Reheat oatmeal in a saucepan or microwave until steaming hot (about 2 minutes in the microwave, stirring halfway), adding 1–3 tablespoons milk to loosen as needed. Reheat apples in the microwave for 30–60 seconds or in a small skillet over medium-low heat for 2–3 minutes. The apples may soften slightly after storing, but they’ll still taste great.
