Full Ingredients
Oatmeal Base
- 1/2 cup (45 g) old-fashioned rolled oats
- 1/2 teaspoon baking powder
- 1/2 teaspoon ground cinnamon
- 1/8 teaspoon fine salt
Wet Ingredients
- 1/2 cup (120 ml) milk (dairy or unsweetened non-dairy)
- 1 large egg
- 1 tablespoon (15 ml) maple syrup (or honey)
- 1/2 teaspoon vanilla extract
Berries
- 1/3 cup (50 g) berries (fresh or frozen), plus a few extra for topping
Toppings (Choose One or Mix)
- 2 tablespoons (30 g) plain Greek yogurt
- 1 tablespoon (16 g) nut butter (peanut, almond, or cashew)
- Optional: 1 teaspoon maple syrup for drizzling

Step-by-Step Instructions
Step 1: Choose the right bowl
Use a microwave-safe bowl that holds at least 16 ounces (about 2 cups). A taller bowl helps prevent overflow as the oats puff while cooking. Lightly coat the bowl with a tiny bit of oil or butter if you want extra insurance against sticking, but it’s not required.
Step 2: Mix the dry ingredients
Add the rolled oats, baking powder, cinnamon, and salt to the bowl. Stir with a fork until everything looks evenly combined. This quick mix helps the baking powder disperse so the oatmeal cooks up fluffy instead of dense.
Step 3: Whisk in the wet ingredients
Pour in the milk, then crack in the egg. Add the maple syrup and vanilla extract. Whisk vigorously with a fork for 20–30 seconds, until the egg is fully blended and you don’t see streaks of egg white. The mixture should look like a loose batter.
Step 4: Fold in the berries
Gently stir in most of the berries, reserving a few for topping. If you’re using frozen berries, break up any large clumps first so they distribute evenly.
Step 5: Microwave, then check the center
Microwave on HIGH for 2 minutes 30 seconds (based on a 1000W microwave). Carefully open the microwave and check the center: it should be starting to look set around the edges but still a little glossy in the middle.
Microwave on HIGH for an additional 45–60 seconds, until the oatmeal has risen and the top looks mostly set. A small, slightly soft spot in the center is ideal; it will continue to firm up as it rests.
Step 6: Rest to set the “baked” texture
Let the oatmeal stand for 1 minute 30 seconds. This resting time is important: it finishes cooking gently, the crumb sets up, and the texture becomes more like baked oatmeal rather than porridge.
Step 7: Top and serve warm
Add the reserved berries on top. Finish with Greek yogurt for a creamy, tangy contrast, or swirl on nut butter for richness. If you like it sweeter, drizzle with 1 teaspoon maple syrup. Enjoy straight from the bowl while it’s warm and cozy.
Pro Tips
- Adjust for your microwave: If your microwave is under 900W, plan on adding 15–30 seconds. If it’s over 1100W, start checking 15–30 seconds early to avoid overcooking.
- Avoid overflow: Use a tall bowl and don’t fill it more than halfway with batter. If your microwave runs hot, pause at 2 minutes 30 seconds and let it settle for 10 seconds before continuing.
- Don’t skip the rest: The 1 minute 30 second rest is what gives you that soft baked-oatmeal texture instead of a wet center.
- Frozen berry tip: Frozen berries may cool the batter, so you may need the full extra 60 seconds. They can also turn the oatmeal purple in the best way.
- For a smoother texture: Stir the oats and liquid together and let sit 1 minute before microwaving so the oats start to hydrate.
Variations
- Blueberry lemon: Use blueberries and add 1 teaspoon finely grated lemon zest. Top with yogurt.
- Peanut butter and strawberry: Use strawberries and top with 1 tablespoon peanut butter and a pinch of extra cinnamon.
- Apple pie: Swap berries for 1/3 cup (45 g) finely chopped apple, add 1/8 teaspoon ground nutmeg, and top with yogurt and a drizzle of maple syrup.
Storage & Make-Ahead
This single serving is best eaten right away, but you can refrigerate leftovers in a covered container for up to 3 days. Reheat in the microwave on HIGH for 45–60 seconds, adding 1–2 teaspoons milk if it seems dry. For make-ahead, combine the dry ingredients in a small jar (oats, baking powder, cinnamon, salt). When ready to eat, add the wet ingredients and berries, then microwave as directed.
