Single Serving Apple Crumble
This Single Serving Apple Crumble bakes up bubbling and golden in one small baking dish. No leftovers, no fuss, just warm cinnamon apple and a buttery oatmeal pecan crumble.
Single Serving Apple Crumble: Fall Dessert Without the Leftovers
I love a good apple dessert, but I don't always want a whole pan of apple crumble. Dare I say, I lack self control when it comes to warm, spiced fall desserts?
So, I developed this Single Serving Apple Crumble for those cool, fall days when the apples are fresh off the trees so I can have a small fruit pie, just for me.
Or if I have a bunch of people, everyone gets their own little dessert! That makes everyone feel special.
I love to top the crumble with a scoop of ice cream or a dollop of Homemade Whipped Cream and siton the porch while I enjoy the cooler weather and beautiful Fall colors. Maybe you'll find a little time the apple season to do the same.
Ingredients & Why They Matter
- Baking Apple - Needs to hold its shape under heat instead of collapsing into mush. I love Granny Smith and Honey Crisp.
- Brown Sugar - Brings molasses moisture that melts into the apple juices and turns into that syrupy pool at the bottom of the baking dish.
- Old-Fashioned Oats - Gives the topping its chew. Skip quick oats here - they turn pasty instead of textured.
- All-Purpose Flour - The structural glue that holds the crumble together in clumps and thicken the yummy juices.
- Pecans, Chopped - Toasty crunch and richness that plays off the soft baked apple underneath.
- Kosher Salt - A single pinch sharpens every other flavor in the dish.
- Ground Cinnamon - The warm backbone. Small quantity, big presence.
- Cold Butter, Cubed - Has to stay cold going in. Cold butter cut into the dry mix is what creates those craggy, buttery crumble pockets instead of a flat paste.

How to Make Single Serving Apple Crumble
1. Prep the Apple and the Oven
Preheat to 375°F and get your apple peeled, sliced, and settled into a small baking dish - an 8-ounce ramekin is the sweet spot for a single portion. Setting the apple aside while you build the topping means it's not sitting exposed and browning any longer than it has to.
2. Build the Crumble Topping
Combine the brown sugar, oats, flour, pecans, salt, and cinnamon in a small bowl, then cut in the cold butter with a fork or your fingers. Work it just until you've got pea-sized, buttery clumps. This is the step people overdo, and it's the difference between a crumble that bakes up craggy and one that melts into a flat sheet.
3. Assemble and Bake
Pour the crumble topping over the apple and bake until golden brown. You're watching for color on top and bubbling around the edges - that bubbling is the sugar and apple juices reducing into syrup, which is exactly what you want pooling at the bottom.
In a Pinch Ingredient Swaps
Ideas to test in your own kitchen before they go in the recipe card:
- Baking Apple - Granny Smith holds its shape best if that's what's in your crisper; Honeycrisp or Braeburn will work but soften a touch more.
- Pecans - Walnuts or sliced almonds could sub in for a different crunch.
- Old-Fashioned Oats - Quick oats in a pinch, knowing the topping will be softer and less textured.
- Butter - A cold, solid coconut oil could theoretically stand in for a dairy-free version.
Creative Variations
- À la Mode - A scoop of vanilla ice cream melting into the warm crumble the second it comes out of the oven.
- Salted Caramel Drizzle - A spoonful of caramel sauce over the top before serving.
- Warm Spice Bump - A pinch of nutmeg or fresh ginger alongside the cinnamon for a deeper spiced-apple flavor.
- Dried Fruit Add-In - A few dried cranberries or raisins tucked under the apple slices before the topping goes on.
Storage & Reheating
The Fridge Life
Once cooled, this keeps covered in the refrigerator for 3-4 days.
The Container Matters
Cover the ramekin directly with plastic wrap or foil rather than transferring it - moving a warm crumble disturbs that syrupy apple layer and the crisp topping.
Can You Freeze It?
The unbaked apple-and-crumble combo freezes well in a ramekin - wrap tightly and bake straight from frozen, adding extra time. A fully baked crumble can be frozen too, though the topping loses some of its crispness on thaw.
Cooking for One or Two
If you're cooking for two, don't scale the recipe up into one bigger dish, just repeat it side by side in two ramekins on the same sheet pan. Each one bakes independently and you both get your own bubbling topping intact.
FAQ
Make sure your butter is cold before building the crumble and don't over mix it.
If you mug is oven-safe, then yes! Any dish marked "oven safe" on the bottom is usable here.
I prefer my apples peeled, but if you like the peeling, leave it on!
