Step-by-Step Instructions
- Preheat Oven:
Set your oven to 350°F (177°C). Spray a 12-cup muffin pan generously with nonstick spray (skip liners if you want to avoid sticking). - Mix Wet Ingredients:
In a large bowl, whisk together milk, eggs, maple syrup (or honey), vanilla extract, and applesauce until smooth. - Add Dry Ingredients:
Stir in the oats, baking powder, cinnamon, nutmeg, and salt. - Fold in Apples & Nuts:
Gently fold in the chopped apples and optional nuts using a spatula. - Fill Muffin Pan:
Evenly divide the mixture into all 12 muffin cups, filling each to the top. Ensure you get both oats and liquid in each cup. - Optional Topping:
Sprinkle a little coarse sugar on top for extra texture and crunch. - Bake:
Bake for 28–30 minutes or until the tops are set and lightly golden. If browning too fast, tent with foil halfway through. - Cool & Serve:
Let them cool in the pan for 5–10 minutes before removing. Serve warm or cool completely for storage.
Helpful Tips:
- The batter will look a bit runny—totally normal! Just stir well before scooping.
- Want extra crunch? Top with chopped walnuts or a sprinkle of coarse sugar before baking.
- Store leftovers in the fridge for up to 1 week or freeze for up to 3 months.
Flavor Ideas to Try:
- Banana: Swap applesauce for mashed banana.
- Blueberry: Use berries instead of chopped apples.
- Chocolate Chip: Stir in a handful of mini chips for a fun twist.
- Nut Butter: Swirl in peanut or almond butter for extra richness.
How to Serve
- Warm with a drizzle of nut butter or maple syrup for a comforting breakfast.
- Top with yogurt and fruit for a protein-packed morning meal.
- Pair with coffee or tea as a light snack.
- Pack in lunchboxes for kids or adults — they hold their shape well and don’t crumble.
Tip: To reheat, microwave for 15–20 seconds or warm in a 350°F oven for 5 minutes.
Storage
- Fridge: Store cooled oatmeal cups in an airtight container for up to 1 week.
- Freezer: Wrap individually or store in a ziplock bag. Freeze for up to 3 months.
- To Thaw: Leave on the counter or refrigerate overnight. Reheat before serving.
Best practice: Freeze in batches to always have a healthy option ready!

Common Mistakes to Avoid
- Skipping the spray (even with liners): These stick easily—always grease your muffin tin well.
- Not mixing the batter well: Make sure oats, liquid, and fruit are evenly distributed in each cup.
- Using steel-cut oats without prepping: These need soaking and longer bake times.
- Overbaking: Leads to dry or tough oatmeal cups. Check at 28 minutes!
- Letting the batter sit too long before baking: The oats will soak up the liquid and throw off the texture. Mix and bake immediately.
❓ Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?

Q: Are these freezer-friendly?
A: Absolutely! Freeze after baking and cooling. Reheat in the microwave or oven before serving.
