“Blotted peaches bubble beneath a loose oat crown while the muffin wells turn every serving edge crisp.”
A tray crumble is impossible to serve neatly and always leaves someone with mostly topping. Baking them in lined wells fixes the ratio for everyone and gives each portion a caramelized edge a big dish simply cannot produce. They also travel, which a bowl of crumble has never managed. Under forty-five minutes from start to rack.
Peaches release a lot of juice, and juice under a crumb topping turns it to porridge from below, so blot the cut cubes on a towel first. Then press the base layer genuinely firm, because a loosely packed base drinks up fruit liquid and collapses the moment you peel the liner away.
🍑 The promise: The crumb has set and browned at the edges, and the peach layer underneath has thickened to jam rather than juice.


The “tender fruit cups with crisp oat crowns” result begins with the first instruction—line a 12-cup muffin pan and heat oven to 350°F (175°C); the final control point comes when you bake 22–27 minutes until peach juices bubble and centers reach 200°F (93°C). The standard 12-cup muffin pan keeps “Bake 22–27 minutes” even across the batch, which matters for tender fruit cups with crisp oat crowns.
Reaching tender fruit cups with crisp oat crowns requires this order: bake 22–27 minutes until peach juices bubble and centers reach 200°F (93°C); only then should you cool 15 minutes in pan, then lift cups to a rack. Rub the cinnamon into the sugar before making the crumbs so its aroma reaches both peach and oat layers.
Line a 12-cup muffin pan with paper liners and heat the oven to 350°F (175°C). Liners matter here because the fruit juices caramelize at the edges and would otherwise glue the cups to the metal.

Dice 2 cups (300 g) peaches into ½-inch cubes and press the cut surfaces onto a towel. Blotting away the loose juice keeps the crumb crown crisp instead of steaming it from below.

Rub ½ cup (113 g) cold butter into 1 cup (120 g) flour, 1½ cups (135 g) oats, ½ cup (100 g) sugar, 1 tsp (4 g) baking powder, and ¼ tsp (1.5 g) kosher salt until the mixture clumps like damp sand.

Press two-thirds of the crumb firmly into the wells to build a base and low wall. Spoon in the peaches, add a spoonful of the 1 cup (245 g) yogurt to each, and scatter the remaining crumb on top.

Bake 22 to 27 minutes, until the peach juices bubble up around the edges and the oat tops turn deep gold. An instant-read thermometer pushed into a center should read 200°F (93°C).

Cool the cups in the pan for 15 minutes before lifting them onto a rack. Straight from the oven the fruit layer is molten and the crumb will slump; a short wait firms both.

The oat crown crunches, the edges are golden, and the peach layer has thickened to a jam. For tender fruit cups with crisp oat crowns, if the surface of Peach Oat Crumble Cups browns before its center sets, shield only the dark area and continue in short intervals. Stop at this cue: Peach Oat Crumble Cups has set crumbs, browned edges, and fruit that looks jammy rather than watery.
Toast the oats in a dry pan for 4 minutes before they go into the crumb, which deepens a topping that carries no spice of its own.
