Apple Crumble (Single Serving)

A single serving version of everyone’s favorite dessert – apple crumble! Sweetened cinnamon apples covered an addicting crumble topping. Hot fruits in dessert might not be for everyone, but they are sure for me! I truly can’t get enough of this delicious, quick, and easy recipe. And, if you’re looking for a larger batch, I have a full size apple crumble recipe too!

Apple Crumble vs. Apple Crisp

These two desserts get mixed up a lot, and I get why. They’re close cousins! But here’s the main difference:
Apple crumble typically has a softer, more cake-like topping without oats.
Apple crisp usually includes oats or nuts in the topping for a crunchier texture.

This version leans crumble—but with a buttery crisp edge that gives the best of both worlds.

Key Ingredients (And Why They Matter)

Apple (Jazz or Honeycrisp): These apples are sweet-tart and hold up well while baking and are typically a little smaller than other varieties (making them ideal for a single serving recipe like this). Avoid super soft apples like Red Delicious—they’ll turn to mush.

Raw or Brown Sugar: Raw sugar adds a nice caramel-like crunch, while brown sugar brings in those deeper molasses notes. Use what you have.

Butter: Melted, always. It helps the topping come together and gives that rich, toasty flavor as it bakes. (More on that below!)

Flour + Cinnamon: The flour builds the crumble structure, and the cinnamon ties the whole thing together with cozy vibes.

Lemon Juice: Just a splash brightens the filling and balances the sweetness.

Vanilla Ice Cream (for serving): Optional… but is it?

How to Make Single Serving Apple Crumble

1. Chop the apple and toss with lemon juice, sugar, cinnamon, and melted butter.
2. Add the apple mixture to a ramekin or small baking dish.
3. Mix flour, sugar, cinnamon, and melted butter by hand to form a clumpy crumble.
4. Layer crumble on top of apples.
5. Bake in a toaster oven at 350°F for 30-35 minutes, until golden and bubbling. For a regular oven, you may need to cook longer (35-40 minutes).
6. Serve with ice cream (or kulfi!) and dig in.

Common Mistakes to Avoid

Mistake: Too dry of a topping. The crumble should look damp and slightly clumpy—not powdery. If it’s dry, mix in more melted butter.
Mistake: Undercooked topping. Make sure the top is golden and the edges are bubbling—this is your visual cue.
Mistake: Wrong apples. Don’t use soft apples that break down too fast (Red Delicious, I’m looking at you).

Serving Suggestions

This single-serving apple crumble pairs beautifully with:

• Homemade rose saffron kulfi on top
• With a chai latte or pumpkin spice milk on the side
• A drizzle of caramel sauce or a sprinkle of crushed biscuits on top

What Are the Best Apples for a Single Serving Apple Crumble?

Look for apples that balance sweet and tart, hold their shape while baking, and are relatively small in size. My go-tos:

• Jazz (sweet, crisp, slightly tangy)
• Honeycrisp (balanced flavor and holds up well)

Avoid apples that are too soft, mealy, or oversized—they tend to break down too much while baking and won’t give you that tender-but-firm bite you’re after.

Why Did You Melt the Butter?

Great question. A lot of classic crumble recipes use cold, cubed butter. But for a single serving? Melted butter saves time and makes mixing the crumble topping way easier. Also, personally, after trying both techniques I actually prefer the consistency the melted butter gives. I’d compare it to the buttery, dense, rich crumble that you find on coffee cakes!

Plus, melting the butter gives you more control over the texture—you can see exactly when the topping turns clumpy and damp (aka the ideal state).
