Peach Cobbler vs. Peach Crisp vs. Peach Crumble
These names are often used interchangeably, but they can refer to different toppings. A peach cobbler typically has a cakey or biscuit-style topping: spooned or dropped batter bakes into a soft top. A peach crumble has a streusel-style topping made from butter, sugar, and flour—often with oats added for texture. Fruit crisps most commonly feature an oat-based topping similar to a crumble. Cobblers tend to be distinct because of their batter or biscuit-like topping, while crisps and crumbles are closer cousins.

Easy Way to Peel Peaches
To peel peaches quickly: score an “X” in the bottom of each fruit, blanch them in boiling water for 20–30 seconds, then transfer immediately to an ice bath for 3–5 minutes. The skins should slip off easily without needing a knife.
About Using Canned or Frozen Peaches
Fresh, firm peaches produce the best texture when baked. I haven’t tested this exact recipe with canned peaches; canned fruit tends to be softer and better suited to no-bake dishes. If using frozen peaches, thaw and drain any excess liquid before assembling to avoid a soggy topping.
Tips for Success
- If your peaches lack sweetness, add up to 1/4 cup granulated sugar to the filling.
- If the peaches release a lot of juice while baking, mix a teaspoon or two of cornstarch into the filling to thicken the juices.
Storing Leftovers
Store leftover peach crumble covered in the refrigerator for up to four days. Reheat in a 350°F oven until warmed through for the best texture. If you use a microwave, heat in short intervals to avoid toughening the oats.
To freeze, place cooled portions in an airtight container and freeze. Thaw overnight in the refrigerator before reheating.
