Apple Cinnamon Oatmeal Cups

Last Tuesday morning, I stood in my kitchen waiting for coffee to brew when my daughter asked if we could make something we could grab on the way to school instead of stopping for pastries every other day. I remembered my grandmother's baked oatmeal, but I wanted something portable, something that felt like a treat but tasted wholesome. These apple cinnamon cups became our solution—they transformed a rushed weekday into a moment where I could send her out the door with something I made myself.

My friend Sarah brought her kids over one Saturday morning, and we made these together while the kids colored at the table. Something about the smell of apples and cinnamon filling the house made everyone slow down a little. By the time they came out of the oven, all four kids were gathered at the counter asking if they could have one warm, with a glass of milk. That's when I knew this recipe had staying power.

Ingredients

• Old-fashioned rolled oats (2 cups): Use the thick-cut kind, not instant—they hold their texture and give you that satisfying bite even after a few days in the fridge.
• Ground cinnamon (1 ½ tsp): This is where the magic lives; don't skip it or measure timidly.
• Baking powder (1 tsp) and salt (¼ tsp): The baking powder keeps these light and tender, while salt quietly deepens the sweetness.
• Large eggs (2): They bind everything together and add richness that makes these feel more cake than cereal.
• Milk (1 ⅓ cups): Dairy or non-dairy both work beautifully; the oats don't discriminate.
• Pure maple syrup or honey (⅓ cup): This sweetens the whole mixture without making it cloying, and it helps them stay moist.
• Melted butter or coconut oil (2 tbsp): Butter tastes richer, but coconut oil works if that's what you have.
• Vanilla extract (1 tsp): A small amount that whispers rather than shouts.
• Peeled, diced apple (1 ½ cups): One large apple, any variety that isn't mealy—I use Granny Smith or Honeycrisp depending on the season.
• Walnuts or pecans (⅓ cup, optional): Toast them first if you want them to taste bolder.
• Raisins or dried cranberries (¼ cup, optional): They plump slightly as these bake, adding little bursts of chewiness.

Instructions

Heat your oven and ready your muffin tin:

Preheat to 350°F and grease a 12-cup muffin tin or line it with paper liners. This matters—stick with the grease even if you're using liners, because nothing ruins a morning like a cup that refuses to release.

Mix the dry base:

In a large bowl, combine oats, cinnamon, baking powder, and salt. Stir gently so everything is evenly distributed; you're looking for a consistent tan color with flecks of cinnamon throughout.

Whisk the wet ingredients:

In a separate bowl, whisk eggs, milk, maple syrup, melted butter, and vanilla until the mixture is smooth and the eggs are fully incorporated. Don't leave streaky egg whites—take a few extra seconds here.

Bring wet and dry together:

Pour the wet mixture into the dry ingredients and stir until just combined. The batter will look thick and porridge-like, which is exactly right; overmixing makes these tough.

Fold in the apples and any extras:

Gently fold in your diced apples and optional nuts or dried fruit. The apples should be scattered throughout, not clumped in one section.

Fill the cups:

Divide the mixture evenly among the muffin cups, filling each almost to the top. A small ice cream scoop keeps this fair and efficient.

Bake until set:

Bake for 25–28 minutes; you're looking for them to be set in the center and lightly golden on top. A toothpick inserted in the middle should come out clean or with just a few moist crumbs clinging to it.

Cool with patience:

Let them rest in the pan for 5 minutes—this helps them set and makes them less likely to crumble when you lift them out. Then transfer to a wire rack to cool completely before wrapping or storing.

I'll never forget the morning my son came downstairs, grabbed one of these from the container, and asked if he could bring extras to share with his soccer team. That's when I realized I'd made something that felt like love in a cup—not fussy, not pretentious, just honest and warm.

Storage and Keeping

These keep beautifully at room temperature in an airtight container for up to 2 days, though the texture stays best if you refrigerate them. In the fridge, they'll last up to 5 days and actually taste even more tender the next day as the oats continue to absorb the liquid. Cold, warm, or gently microwaved for 20 seconds—they work any way you want them.

Variations Worth Trying

Once you make these once, you'll want to play. Swap the apples for diced pears in the fall or add fresh blueberries and lemon zest in summer. Ginger and apple is a stunning combination, and if you're feeling adventurous, a tiny pinch of nutmeg or cardamom adds mystery. I've even made a version with banana and chocolate chips for weekend mornings when we wanted something that felt more indulgent.

Make-Ahead Magic

These are the definition of a Sunday project with weekday payoff. Bake a full batch while you're catching up on laundry or a podcast, and you've solved breakfast questions for nearly a week. They freeze beautifully too—wrap individually and store in a freezer-safe bag for up to a month. Thaw overnight in the fridge or pop one directly into the toaster oven on a lazy Saturday morning.

• Freeze them on a baking sheet first before stacking in a bag so they don't stick together.
• If you're making these for someone else, wrap them in parchment and tie with twine—they make a thoughtful, edible gift.
• Double the batch and bake in two tins; the oven space is free anyway, and you'll be grateful later.
