Tips

Tip 1

Don't overmix when folding in the peaches - gentle folding keeps the fruit intact and prevents tough cake texture.

Tip 2

Check doneness by inserting a toothpick in the center - it should come out mostly clean with just a few moist crumbs.

Tip 3

Let the cake rest for 10-15 minutes after cooking to firm up before serving for cleaner slices.

FAQ

Can I use fresh peaches instead of canned?

Yes, use about 4-5 fresh peaches, peeled and sliced. Add 2-3 tablespoons water to replace the missing syrup moisture.

Can I make this in a regular oven?

Bake in a greased 9x13 pan at 350°F for 35-45 minutes until golden and center is set.
