⭐Why I Love It:
- Crispy Oat Topping – Rolled oats provide the signature crunch and golden texture that make a crisp so satisfying.
- Small Batch Dessert – This recipe makes a single portion, ideal when you want a fresh-baked treat without leftovers.
- Only One Apple – Requires a single medium-large apple, and peeling is optional to save time.
🥘Ingredients

For the Crisp Topping
- Melted Unsalted Butter – Helps bind the topping; if using salted butter, omit added salt.
- Brown Sugar – Packed brown sugar adds moisture and caramel notes; light or dark both work.
- Rolled Oats – Old-fashioned oats create the crunchy texture for the topping.
- All-Purpose Flour – Helps form clumps in the topping; substitute a 1:1 gluten-free blend if needed.
- Ground Cinnamon – Adds warmth to the topping and pairs well with apples.
Apple Filling
- Apple – Use any baking apple you like (Granny Smith, Honeycrisp, etc.). Dice with or without the peel.
- All-Purpose Flour and Granulated Sugar – A small amount thickens and sweetens the filling so juices aren’t runny.
- Ground Cinnamon – Balances the sweetness and enhances apple flavor.

🔪Step by Step
This Single Serve Apple Crisp is a quick small-batch dessert that comes together in minutes and bakes to a bubbly, golden finish.

💭Recipe Tips
- Storage – Store leftovers covered in the fridge for up to 5 days, or keep at room temperature up to 2 days.
- Measure Flour Correctly – Use the spoon-and-level method to avoid packing too much flour, which can affect texture.
- Peel or Not – Leaving the peel on saves prep time and adds texture; peel if you prefer a smoother bite.

- Method: Oven
- Cuisine: American
Ingredients
Apples
- 1 medium-large apple, diced (skin on or off)
- 2 teaspoons all-purpose flour
- 2 teaspoons granulated sugar
- ⅛–¼ teaspoon ground cinnamon, to taste
Crisp Topping
- 1 tablespoon packed brown sugar
- 2 tablespoons melted unsalted butter
- 3 tablespoons all-purpose flour
- 2 tablespoons rolled oats
- Pinch of salt (omit if using salted butter)
Instructions
- Preheat: Preheat oven to 350°F. Grease a ramekin with butter or nonstick spray.
- Prepare Apples: Toss the diced apple with the flour, sugar, and cinnamon. Transfer to the greased ramekin.
- Make Topping: Stir together the brown sugar, melted butter, flour, oats, and salt until clumps form. Crumble evenly over the apples.
- Bake: Bake about 35 minutes, until topping is golden, apples are tender when pierced, and juices bubble. Baking time can vary with ramekin size and apple pieces; cover with foil if topping browns too quickly.
- Serve: Let cool slightly so juices thicken, then enjoy warm.
Notes
Ramekin Size – A 10 oz ramekin (about 4.25 inches wide) is pictured, but a 7–8 oz ramekin works for smaller apples. It’s fine if the ramekin is full — the apple will reduce as it bakes.
