This Peach Cake with Brown Sugar Frosting can be enjoyed all year with fresh, frozen, or canned peaches. It’s a breeze to prepare using a boxed cake mix, jello powder, and sliced peaches. Topped with a luscious brown sugar frosting that tastes like whipped caramel, each bite is a luxurious delight.
Sometimes, you crave a simple dessert. This easy peach cake recipe begins with a box of cake mix and a packet of jello, much like the beloved strawberry jello cake.
Imagine a cake that starts with the convenience of a boxed mix and jello—featuring real peaches that add incredible moisture (and yes, a fair amount of oil). It’s crowned with a sumptuous brown sugar frosting!
Using shortcuts like pre-packaged ingredients makes the cake quick to assemble, freeing up more time for you to perfect the frosting. The brown sugar frosting, rich and unique, resembles whipped caramel in both taste and texture.
This cake is an indulgent, summery treat. Brimming with peaches and topped with a decadent brown sugar frosting, it’s not for those who prefer mild desserts. Ideal for birthdays or barbecues, this cake features frosting that’s cooked, cooled, and whipped to fluffy perfection, creating a sinfully tasty topping. Each bite offers a harmony of perfectly cooked peaches and moist cake, all enhanced by the rich frosting.
The secret to its full flavor isn’t just the fresh peaches; it’s also the peach jello mixed into the batter. Without the jello, it would merely be a yellow cake with peaches—not a true peach cake. The inclusion of jello transforms it into an authentic peach delight, perfect for sunny days and sure to be a crowd-pleaser once tasted!

Ingredients for Peach Cake With Brown Sugar Frosting
Let’s dive into the mouthwatering world of peach cake baking, but first, let’s talk about the key ingredients that will make your cake a standout success:
- Yellow Cake Mix: Think of this as your secret weapon for a deliciously fluffy base. Choosing a high-quality brand really makes a difference in flavor, so don’t skimp here!
- Peach Jello: This isn’t just for kids’ desserts; adding peach Jello amplifies the peachy punch of your cake and helps keep it wonderfully moist.
- Peaches: You can go fresh or frozen, but ensure they’re ripe and bursting with flavor. Fresh peaches are my go-to for that unbeatable texture and taste, though frozen peaches are a fantastic substitute when they’re not in season.
- Brown Sugar: We’re using this gem in our frosting to achieve that irresistible deep caramel flavor. Opt for dark brown sugar if you can—it really enriches the taste.
- Heavy Cream: A must for our frosting, it adds that luxurious creaminess and balances the sweetness beautifully.

How To Make This Peach Cake With Brown Sugar Frosting
Today, I’m excited to guide you through the delightful process of making a perfect peach cake that’s sure to impress! Start by setting your oven to 350º F and lightly greasing your baking dish. In a large bowl, whisk together the yellow cake mix, peach jello, eggs, vegetable oil, and a splash of vanilla extract until just combined—be careful not to overmix, as this can make your cake dense. Next, gently fold in the chopped peaches. Pour the batter into your greased dish and bake for about 45 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely once baked.
For the frosting, combine brown sugar, heavy cream, and butter in a saucepan and bring the mixture to a boil. Let it boil for just one minute, then remove from heat. Stir in vanilla and a pinch of salt. If you’re using an ice bath to cool the frosting, now’s the time to set your saucepan in it. Stir continuously to keep the frosting smooth and prevent it from becoming grainy. Once the frosting has thickened, whip it until fluffy and spread over your cooled cake. Enjoy this luscious peach cake fresh for the best flavor, though it can be stored for a few days if covered properly. Happy baking!

Storage Options
Want to savor every bite of your Peach Cake with Brown Sugar Frosting for days? Here’s how to keep it perfectly fresh: Refrigerate your cake for up to five days, ensuring it’s snugly wrapped in plastic or tucked away in an airtight container. This keeps it moist and flavor-rich, safeguarding it from other scents mingling in your fridge. Got leftovers you’d like to save for later? Freeze the unfrosted cake for up to three months by wrapping it first in plastic and then in foil to shield it from freezer burn. When you’re ready to enjoy it again, just thaw it overnight in the refrigerator, frost, and serve. Perfect for satisfying that sweet tooth anytime!
