The Anatomy of a Perfect Crumble

A great Single-Serve Apple Crumble is all about the delightful contrast between two key components:

  1. The Saucy Fruit Filling: By pre-cooking the apples on the stovetop with sugar and cinnamon, we ensure they become perfectly tender and release their juices. We then thicken these juices with a simple cornstarch slurry. This creates a luscious, gooey, and perfectly spiced filling that isn’t watery or runny.
  2. The Crunchy Oat Topping: Our crumble topping uses melted butter, which creates a different texture than a traditional crumble made with cold butter. Instead of a flaky, pastry-like topping, the melted butter creates wonderful, crunchy clusters and a crisp, golden-brown top. The addition of rolled oats provides a fantastic, chewy texture.

Choosing the Best Apples for Baking

The type of apple you choose will have a big impact on the final texture and flavor of your Single-Serve Apple Crumble. Here are some great options:

  • For Firm, Tart Apples: Granny Smith is the classic choice. It holds its shape well when cooked and its tartness is a perfect balance to the sweet crumble topping.
  • For Firm, Sweet Apples: Honeycrisp, Gala, Fuji, or Braeburn are all excellent choices. They will hold their shape and provide a sweeter filling.
  • For Softer, “Saucy” Apples: If you prefer a filling that breaks down into more of a chunky applesauce texture, a McIntosh apple is a great option.

The Key Ingredients for Your Apple Crumble for One

This recipe for a Single-Serve Apple Crumble uses simple, comforting pantry staples.

  • Apples: Two small apples or one large apple is the perfect amount for a generous single serving.
  • For the Filling: Brown sugar provides a warm, molasses-like sweetness, while cinnamon adds that classic spice. A simple cornstarch slurry (corn flour in some regions) is the key to a thick, gooey sauce.
  • For the Crumble: A simple mix of plain flour, rolled oats, brown sugar, and cinnamon creates the perfect chewy and crunchy topping. Melted unsalted butter brings it all together.

Step-by-Step Guide to Your Single-Serve Apple Crumble

This easy recipe comes together in just a few simple stages. Get ready for the ultimate cozy treat!

Part 1: Make the Apple Filling

  1. Prepare your Oven: First, pre-heat your oven to 190°C / 375°F.
  2. Combine Filling Ingredients: In a small pot, add your peeled and chopped apples, 2 tablespoons of water, 1/2 teaspoon of ground cinnamon, and 2 tablespoons of brown sugar.
  3. Cook the Apples: Place the pot on medium heat and stir everything together. Continue to cook, stirring occasionally, until the apples have softened to your desired tenderness.
  4. Thicken the Filling: In a tiny bowl, mix the 1 teaspoon of corn flour (cornstarch) with 1 teaspoon of water to create a smooth slurry. Pour this into the pot with the apples and stir it in. Continue to heat while stirring until the apple mixture thickens into a beautiful, glossy sauce. This will only take about 30 seconds. Remove the pot from the heat and set it aside.

Part 2: Make the Crumble and Bake

  1. Make the Crumble Topping: In a small bowl, add the 4 tablespoons of plain flour, 2 tablespoons of oats, 2 tablespoons of brown sugar, and 1/4 teaspoon of ground cinnamon. Mix these dry ingredients together.
  2. Add the Butter: Pour the 25g (about 2 tablespoons) of melted butter into the bowl and mix with a fork until you get a clumpy, crumbly mixture. Don’t overmix!
  3. Assemble Your Crumble: In a ramekin or any other small, oven-safe dish, spoon in the apple filling. Then, generously sprinkle the crumble topping all over the top.
  4. Bake to Perfection: Place your Single-Serve Apple Crumble on a small baking sheet (to catch any potential drips) and bake for about 15 minutes, or until the crumble topping has turned a beautiful golden brown and the filling is bubbly.
  5. Cool and Serve: Let your crumble cool down for a few minutes, as it will be very hot. Then, top it with a scoop of vanilla ice cream or a drizzle of warm custard and enjoy your perfect, homemade Single-Serve Apple Crumble.

Yes, absolutely! This recipe is a perfect template. Try it with a chopped pear, a handful of mixed berries, or a sliced peach for a delicious seasonal variation of this Single-Serve Apple Crumble.
