Common Questions
Do I prepare the cake mix first?
Nope. Use the cake mix dry. You are basically making a buttery crumb topping as it bakes.
Do I need to peel the peaches?
You do not have to, but I prefer peeled peaches for the softest filling. If you want an easy peel: score an X on the bottom, blanch in boiling water for 30 seconds, then move to an ice bath. The skins slip right off.
Can I use canned peaches?
Yes. The goal is about 6 cups sliced peaches (drained) so you get a nice, juicy layer. That is usually around 4 cups drained per 29-ounce can, so two 29-ounce cans often gets you closest. If you only have 15-ounce cans, plan on 3 to 4 cans to reach about 6 cups drained, since brands vary. Drain well for a thicker filling, or keep a few tablespoons of juice for a saucier cobbler. If your peaches are in heavy syrup, reduce the brown sugar a bit.
Can I use frozen peaches?
Absolutely. Use them straight from frozen. Add 1 extra tablespoon cornstarch and plan on an extra 5 to 10 minutes of bake time, since frozen fruit releases more liquid. If your peaches look very icy or watery in the bag, add another tablespoon of cornstarch or just bake until the center is bubbling hard.
Why is my topping still powdery?
Usually it needs a little more butter coverage. Try gently drizzling 2 to 4 more tablespoons melted butter over any dry patches and bake 5 more minutes. Also make sure you sprinkle the cake mix in a nice even layer.
How much butter do I really need?
3/4 cup (12 tablespoons) is my sweet spot for crisp edges and a tender middle. If you want the topping fully moistened with fewer dry pockets, you can use up to 1 cup melted butter, especially if your cake mix seems extra dry.
Can I add nuts or oats?
Yes. Add 1/2 cup chopped pecans or walnuts over the cake mix before the butter. For oats, add 1/2 cup old-fashioned oats mixed into the dry cake mix for a slightly heartier top.
What is the best pan to use?
A 9x13-inch baking dish is the easiest and most forgiving. If your peaches are extra juicy (or you are using a deeper dish), set it on a rimmed sheet pan to catch any bubbly drips.
