Warm, bubbly, and comforting, Miniature Peach Crumbles feature tender, cinnamon-kissed peaches tucked beneath a golden, buttery oat-streusel topping. Baked in individual ramekins, these single-serve desserts offer all the nostalgic warmth of a classic summer peach crisp in a fraction of the time.
The secret to a fast, jammy peach filling without excess liquid is Tossing Fresh or Frozen Peach Slices with Cornstarch, Brown Sugar, and a Splash of Lemon Juice Before Air-Frying or Baking in High-Heat Ramekins. The cornstarch thickens the peach juices almost instantly into a silky glaze beneath the crisp oat crumble.

Ingredients You’ll Need
- Juicy Peach Filling: 2 large ripe peaches (diced into ½-inch cubes; or 2 cups frozen diced peaches), 1½ tablespoons light brown sugar, 1 teaspoon cornstarch, ½ teaspoon fresh lemon juice, and ½ teaspoon ground cinnamon.
- Crispy Oat Streusel: ⅓ cup rolled old-fashioned oats, 2 tablespoons all-purpose flour (or almond flour), 2 tablespoons light brown sugar, 2 tablespoons cold unsalted butter (cubed), and a pinch of fine sea salt.
- For Serving: Vanilla bean ice cream or fresh whipped cream.
Step-by-Step Instructions
1.Toss Spiced Peach Filling:3 mins.
In a bowl, toss diced peaches with 1½ tablespoons brown sugar, cornstarch, lemon juice, and cinnamon until well coated. Divide fruit evenly between two 6-oz oven-safe ramekins.
2.Rub Oat Streusel Topping:3 mins.
In a small bowl, combine rolled oats, flour, 2 tablespoons brown sugar, and salt. Add cold cubed butter and use your fingertips to rub the butter into the dry ingredients until coarse, pea-sized crumbs form.
3.Top Ramekins Generously:1 min.
Spoon the streusel topping evenly over the peaches in both ramekins, pressing down lightly so the oat mixture covers the fruit completely.
4.Air Fry or Bake to Golden:8-10 mins.
Air Fryer Method: Air fry at 350°F (175°C) for 8 to 10 minutes until the top is deep golden and juices bubble.
Oven Method: Bake at 400°F (200°C) for 12 to 14 minutes.
5.Serve Warm with Ice Cream:1 min.
Let cool for 2 minutes, then top each warm crumble immediately with a scoop of cold vanilla bean ice cream and enjoy!

Tips from the Kitchen
- Keep the Peeling Optional: Leaving peach skins on adds vibrant color, extra fiber, and saves prep time—just wash thoroughly before dicing.
- Use Cold Butter for Crisp Streusel: Cold butter creates distinct pockets of crisp crumble as it melts; warm or melted butter can make the topping heavy and dense.
- Add Toasted Pecans: Mix 1 tablespoon of chopped pecans or walnuts into the oat streusel for extra nuttiness and crunch.
