This small-batch apple crumble for two bakes in two individual 10-ounce ramekins. The filling uses two apples, while melted butter creates a crisp oat topping without a pastry cutter. It is sized for a quiet dessert night rather than a crowd.
RECIPE CARD
Small-Batch Apple Crumble for Two
Ingredients
- 1 teaspoon unsalted butter, softened, for the ramekins
- 2 medium firm apples (about 10 ounces/285 grams before coring), peeled, cored, and cut into 1/2-inch cubes (about 2 cups)
- 1 tablespoon packed light brown sugar
- 1 teaspoon fresh lemon juice
- 1 teaspoon cornstarch
- 1/2 teaspoon ground cinnamon
- 1 small pinch fine salt
- 1/3 cup (30 grams) old-fashioned rolled oats
- 1/4 cup (30 grams) all-purpose flour
- 3 tablespoons (38 grams) packed light brown sugar
- 1/4 teaspoon ground cinnamon
- 1 small pinch fine salt
- 3 tablespoons (42 grams) unsalted butter, melted and cooled for 2 minutes
Quick Method
Condensed overview. Use Full Instructions for the complete method, timing and doneness details.
- Preheat and prepare the ramekins: Heat the oven to 375°F (190°C). Butter two oven-safe 10-ounce ramekins and place them on a rimmed baking sheet.
- Mix the apple filling: Combine the apple cubes with 1 tablespoon brown sugar, lemon juice, cornstarch, 1/2 teaspoon cinnamon, and salt. Rest for 5 minutes.
- Make the oat topping: Stir oats, flour, 3 tablespoons brown sugar, 1/4 teaspoon cinnamon, and salt. Mix in melted butter until pea-size clumps form.
- Fill the ramekins: Divide the apples and juice evenly between the ramekins, then scatter half the loose crumble topping over each.
- Bake until bubbling: Bake for 25 to 30 minutes, until the topping is golden, juices bubble in several spots, and a center apple cube is tender with…
- Rest and serve: Cool on the baking sheet for 10 minutes so the filling thickens, then serve the hot ramekins on small plates.
The useful cues are visible: cut the fruit evenly, keep the topping in loose clumps, and bake until juices bubble around the apples—not merely until the surface looks brown.
Why This Small Batch Works
- Two defined portions: the mixture fits two oven-safe 10-ounce ramekins without relying on a vague “small dish.”
- Even apple cubes: half-inch pieces soften within the same window that browns the topping.
- Cornstarch controls the juices: one teaspoon lightly thickens the modest amount of fruit.
- Melted-butter topping: it forms reliable clumps with a fork and needs no special tool.
Ingredients
Apple Filling
- 1 teaspoon unsalted butter, softened, for the ramekins
- 2 medium firm apples (about 10 ounces/285 grams before coring), peeled, cored, and cut into 1/2-inch cubes (about 2 cups)
- 1 tablespoon packed light brown sugar
- 1 teaspoon fresh lemon juice
- 1 teaspoon cornstarch
- 1/2 teaspoon ground cinnamon
- 1 small pinch fine salt
Oat Crumble Topping
- 1/3 cup (30 grams) old-fashioned rolled oats
- 1/4 cup (30 grams) all-purpose flour
- 3 tablespoons (38 grams) packed light brown sugar
- 1/4 teaspoon ground cinnamon
- 1 small pinch fine salt
- 3 tablespoons (42 grams) unsalted butter, melted and cooled for 2 minutes
Use apples that remain pleasantly structured when baked, such as Honeycrisp, Pink Lady, Braeburn, or Granny Smith. A sweet-tart pair gives the filling more depth. Quick oats absorb differently and will make a finer, less distinct topping.
Equipment and Pan Size
- Two oven-safe 10-ounce ramekins, approximately 4 inches across
- One rimmed baking sheet
- Two medium mixing bowls
- Fork, flexible spatula, peeler, and knife
Do not substitute small drinking glasses or decorative bowls unless the manufacturer identifies them as oven-safe at 375°F (190°C). If using one small baking dish instead, choose roughly 5 by 7 inches and begin checking at 25 minutes.
Step-by-Step Instructions
1. Preheat and Prepare the Ramekins
Heat the oven to 375°F (190°C) with a rack in the center. Rub the softened teaspoon of butter inside two oven-safe 10-ounce ramekins. Set both on a rimmed baking sheet so any bubbling juice is contained.
2. Mix the Apple Filling
Place the half-inch apple cubes in a bowl. Add 1 tablespoon brown sugar, lemon juice, cornstarch, 1/2 teaspoon cinnamon, and a pinch of salt. Fold until no dry cornstarch remains. Let the bowl stand for 5 minutes while you make the topping; a light sheen of juice is normal.
3. Make Coarse Oat Clumps
In the second bowl, stir the rolled oats, flour, 3 tablespoons brown sugar, 1/4 teaspoon cinnamon, and a pinch of salt. Pour in the melted butter. Mix with a fork until the flour is moistened and the topping holds together in loose pea-size clumps. Stop before it becomes a compact dough.
4. Fill the Two Ramekins
Divide the apples and any juice evenly between the ramekins. Sprinkle half the crumble over each without pressing it flat. Keep the mixture just below the rim and wipe away stray sugar or butter from the outside.
5. Bake Until the Filling Bubbles
Bake for 25 to 30 minutes. The crumble is ready when the topping is golden, apple juices bubble at several points around the edge, and a thin knife slides into a center apple cube with only slight resistance. If the top browns before the fruit is tender, loosely cover the ramekins with foil for the remaining time.
6. Rest Before Serving
Move the baking sheet to a heat-safe surface and rest the ramekins for 10 minutes. The filling continues to thicken as it cools. The ceramic remains hot, so serve on small plates and warn diners not to touch the ramekins.
Doneness Cues That Matter
| Cue | Not ready | Ready |
|---|---|---|
| Topping | Pale with visible dry flour | Golden with crisp-looking oat ridges |
| Filling | No active bubbles | Juice bubbles in several spots around the fruit |
| Apple texture | Knife meets a hard crunch | Knife enters with slight resistance; cubes still hold shape |
| After resting | Juice looks thin and boiling hot | Juice lightly coats the apples after 10 minutes |
Substitutions and Variations
- One tart and one sweet apple: combine Granny Smith with Honeycrisp or Pink Lady.
- Warm spice: replace 1/4 teaspoon of the filling cinnamon with ground ginger or cardamom.
- Without oats: replace the 30 grams of oats with 30 grams additional all-purpose flour; the topping will be more like a classic flour crumble.
- Frozen fruit: is not a direct one-for-one substitution here because it releases liquid at a different rate.

Troubleshooting
- Watery filling: the apples may be cut too large, the cornstarch may be unevenly mixed, or the filling may not have bubbled. Continue baking in 3-minute increments.
- Dry, sandy topping: mix until every floury patch is moistened. Your tablespoon measure may also have been underfilled.
- Dense topping: do not press it onto the apples; loose clumps create crisp edges.
- Burned edge with firm apples: tent loosely with foil and continue until the center cube is tender.
- Overflow: the ramekins may be smaller than 10 ounces or overfilled. Keep them on the rimmed sheet and leave space below the rim.
Serving, Storage, and Reheating
Serve warm as-is or add a small spoonful of vanilla yogurt or ice cream after the 10-minute rest. For another cozy apple bake, pair a later breakfast with this moist apple cinnamon bread.
Cover cooled leftovers and refrigerate within 2 hours. Use within 3 to 4 days. Reheat an uncovered ramekin at 325°F (165°C) for about 10 to 15 minutes, until hot in the center and the topping is crisp again. Confirm that the ramekin is safe to move directly from refrigeration toward heat; when in doubt, let it lose its chill while the oven preheats to reduce thermal-shock risk.
Frequently Asked Questions
Can I make the crumbles ahead?
You can mix the dry topping and prepare the ramekins several hours ahead. Refrigerate the apples separately after mixing, then assemble just before baking so the topping stays distinct.
Do I have to peel the apples?
No, but peeling gives this short bake a more uniform tender texture. If leaving the skin on, choose thin-skinned apples and cut the cubes no larger than half an inch.
Can I use instant or quick oats?
They will work in a pinch, but the topping will be finer and may absorb the butter differently. Old-fashioned rolled oats give clearer, crisper flakes.
Can I double this recipe?
Yes. Use four 10-ounce ramekins or an appropriately sized baking dish. Keep the ingredient ratios unchanged and judge doneness by bubbling filling and tender apples rather than time alone.
