A soft, peach-studded cake with a buttery brown sugar frosting that cracks when sliced, ready in under an hour.
Equipment
- Oven
- 9x12 baking pan
- Toothpick
- Saucepan
- Whisk
- Refrigerator (optional)
Ingredients
Main
- 15 ounces yellow cake mix
- 3 large eggs
- 0.33 cup vegetable oil
- 0.5 cup peach nectar or peach juice
- 1 pound peaches peeled and chopped, about 2-3 medium
- 1 drop orange food coloring optional
- 0.5 cup unsalted butter cut in pieces
- 0.5 cup heavy cream
- 1 cup brown sugar packed
- 1 teaspoon vanilla extract
- 2.5 cups confectioner's sugar sifted
Instructions
- Preheat your oven to 350°F. Lightly spray a 9x12 baking pan with cooking spray or grease it with butter. Set it aside.
- In a large bowl, blend together the yellow cake mix, 3 large eggs, 1/3 cup vegetable oil, 1/2 cup peach nectar (and the drop of food coloring if using) until well combined. It should be smooth with no dry streaks — about 30 seconds with a whisk. Don't overmix.
- Gently fold the chopped peaches into the batter with a spatula. Overmixing at this stage can break up the peaches and make the cake dense. Just a few folds until they're evenly distributed.
- Pour the batter into the prepared pan and spread it evenly. Bake for 28 minutes, or until done — test with a toothpick inserted in the center; it should come out without wet batter clinging to it, but a few moist crumbs are fine. The sides will just start to pull away from the pan. Let the cake cool in the pan on a wire rack for exactly 5 minutes while you make the frosting.
- While the cake bakes, combine 1/2 cup unsalted butter (cut in pieces), 1/2 cup heavy cream, and 1 cup packed brown sugar in a medium saucepan. Bring to a boil over medium heat, stirring constantly. Once it reaches a full rolling boil — large bubbles that don't stop when you stir — let it boil for a full minute. Remove from heat and add 1 teaspoon vanilla extract and the sifted 2 1/2 cups confectioner's sugar. Whisk vigorously until the frosting is smooth and all lumps are gone. If it's too thick or lumpy, put it back on low heat for a few seconds and whisk again — but don't let it boil.
- Working quickly, pour the frosting over the warm cake (the 5-minute rest is perfect). Tilt the pan gently to spread it evenly if needed — but try to get it right on the first pour, because the frosting sets fast and you won't be able to spread it without cracking the surface.
- Let the frosting set at room temperature until firm, about 30 minutes. If you're in a hurry, pop the pan in the refrigerator for 15 minutes. Once set, slice with a sharp knife — the top will crackle perfectly.
Notes
Don't overmix the batter after adding peaches.
Boil the frosting for a full minute once it reaches a rolling boil.
Let the cake cool exactly 5 minutes before pouring.
If your frosting feels too thin after pouring, wait 10 minutes.
Room temperature eggs make a real difference.
