Why You Will Love This Recipe

This Peach Cake with Brown Sugar Frosting is a guaranteed crowd-pleaser for so many reasons! It’s unbelievably easy to make, using a box cake mix and Jell-O as a base, which means less fuss and more flavor. The addition of real frozen peaches makes the cake incredibly moist and bursting with fruity deliciousness. And the brown sugar frosting? It’s a decadent, caramel-like topping that perfectly complements the peachy cake. Even those who are skeptical of box mixes and Jell-O often fall in love with this cake!

Ingredients

• 1 (15-ounce) box yellow cake mix
• 2 (3-ounce) boxes peach Jell-O powder
• 4 large eggs
• 1 cup oil (light tasting olive oil or vegetable oil recommended)
• 1 (16-ounce) bag frozen sliced peaches, do not thaw
• 1/2 cup (1 stick) salted butter
• 2 cups packed brown sugar
• 2/3 cup heavy cream
• 1 teaspoon vanilla extract
• Ice water (for ice bath, not added to frosting)

Step-by-Step Instructions

1. Preheat your oven to 350 degrees F (175 degrees C). Grease and flour a 9×13 inch cake pan.
2. In a large mixing bowl or the bowl of a stand mixer, combine the yellow cake mix, peach Jell-O powder, eggs, and oil. Beat until well combined and smooth.
3. Open the bag of frozen sliced peaches. Cut each peach slice in half to create more uniform, bite-sized pieces.
4. Gently fold the halved frozen peach slices into the cake batter using a sturdy wooden spoon or spatula.
5. Pour the batter evenly into the prepared cake pan.
6. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached (a few moist crumbs are okay, but no wet batter). The edges of the cake will likely be quite brown, which adds to the flavor.
7. Remove the cake from the oven and let it cool completely on a wire rack.
8. While the cake is cooling, prepare the brown sugar frosting. In a medium saucepan (at least 2-quart capacity), combine the butter, brown sugar, and heavy cream.
9. Cook over medium-high heat, stirring constantly, until the mixture comes to a rolling boil (bubbles across the entire surface). Once boiling, set a timer for 1 minute and continue to stir frequently.
10. Remove the saucepan from the heat and stir in the vanilla extract.
11. Prepare an ice bath by filling a larger bowl with ice water. Carefully place the saucepan containing the frosting into the ice bath. Ensure no water gets into the frosting.
12. Allow the frosting to cool in the ice bath, stirring and scraping the sides occasionally, until it reaches room temperature and has thickened considerably.
13. Once thickened, use a hand mixer to beat the frosting for about 3-5 minutes. It should be thick but still pourable.
14. Pour and spread the warm, pourable brown sugar frosting evenly over the completely cooled cake.

Expert Tips / Pro Tips

To ensure your Peach Cake with Brown Sugar Frosting turns out perfectly, keep these tips in mind:

• Accurate Measurements: Using the exact sizes of cake mix and Jell-O boxes specified is crucial for the correct texture and flavor balance.
• Don’t Thaw the Peaches: Adding the frozen peaches directly to the batter helps keep the cake moist and prevents the peaches from becoming mushy.
• Ice Bath for Frosting: The ice bath is key to achieving the perfect pourable yet set consistency for the brown sugar frosting. It cools the mixture quickly and helps it thicken without becoming too stiff.
• Cool the Cake Completely: Ensure the cake is entirely cool before frosting. Applying frosting to a warm cake will cause it to melt and slide off.
• Watch the Frosting Boil: The 1-minute boil time is important for the frosting’s texture. Don’t over-boil, or it might become too hard.

Variations & Substitutions

While this recipe is delightful as is, feel free to experiment:

• Fresh or Canned Peaches: If fresh or canned peaches are more accessible, use them, but ensure they are very well-drained before adding to the batter.
• Different Jell-O Flavors: While peach Jell-O enhances the peach flavor, you could try other complementary flavors like apricot or even strawberry for a different color and taste profile.
• Cream Cheese Frosting: If brown sugar frosting isn’t your preference, the cream cheese frosting from the Blackberry Cake recipe (omitting coconut extract) would also be delicious.
• Butter Instead of Oil: For the cake, you can substitute 2 sticks (1 cup) of melted butter for the oil if you prefer a butter-based cake.

Serving Suggestions

This Peach Cake with Brown Sugar Frosting is wonderful on its own, but here are a few ideas to enhance your serving experience:

• Serve a warm slice with a scoop of vanilla bean ice cream for a classic dessert pairing.
• Top with a dollop of whipped cream and a few fresh peach slices for extra elegance.
• Enjoy a slice with a cup of coffee or tea for a delightful afternoon treat.
• This cake is also fantastic for potlucks, picnics, or any celebration where a show-stopping, yet easy, dessert is needed.

Storage, Freezing & Reheating

• Storage: Store the cake at room temperature, covered, for up to 2 days. For longer storage, keep it refrigerated in an airtight container for up to 5 days.
• Freezing: This cake freezes beautifully. You can freeze individual slices or the entire cake. Wrap tightly in plastic wrap, then in aluminum foil or place in an airtight freezer-safe container. It can be frozen for up to 3 months.
• Reheating: If frozen, thaw overnight in the refrigerator. If the cake has been refrigerated and you prefer it at room temperature, let it sit out for about 30 minutes before serving. The frosting is best at room temperature.

FAQ

Can I use fresh peaches instead of frozen?

Yes, you can use fresh or canned peaches. If using fresh or canned, make sure they are very well-drained before folding them into the batter to avoid making the cake too wet.

What if I don’t have peach Jell-O?

While peach Jell-O complements the cake, you can substitute it with another fruit-flavored Jell-O like apricot or even strawberry. Keep in mind this will alter the color and flavor profile slightly.

How do I get the brown sugar frosting to thicken?

The ice bath is the key to thickening the frosting to the correct consistency. It cools the mixture rapidly, allowing it to thicken while remaining pourable. Beat it with a hand mixer after cooling to achieve the final texture.

Can I make this cake without a cake mix?

This recipe is specifically designed for a cake mix base. Adapting it to a from-scratch cake would require significant recipe adjustments and is not recommended for this particular recipe.

Why are the edges of the cake so brown?

The combination of Jell-O and the high sugar content in the batter can cause the edges to brown more deeply. This browning contributes to a delicious, slightly chewy texture that is characteristic of this cake.
