Best Peach Cake Brown Sugar

Category: Sweet Treats Without Turning On the Oven

This moist peach cake pairs the irresistible sweetness of peaches with a decadent brown sugar frosting, all in a simple dessert that starts with a cake mix and peach gelatin. Real peach pieces add flavor, while a generous layer of creamy caramel-like icing brings a rich finish. Frozen or canned peaches work well, making it a convenient year-round treat. After baking, let the cake cool before spreading on the warm brown sugar frosting, beaten till light but still pourable. The result is a dessert with layers of flavor and texture, perfect for sharing or indulging any time you want something special.

This peach cake is the kind of dessert you end up craving every summer and reaching for when you want bright fresh flavors any time of year. I started making it when I wanted something easy with big fruit flavor and now it disappears at every family gathering. The sweet brown sugar frosting makes this cake taste bakery-worthy but you will be amazed how fast it all comes together.

I pulled this out of the oven at a picnic once and nobody could believe it started with a cake mix. The frosting gets the most compliments and there are rarely leftovers.

Ingredients

  • Yellow cake mix: Choose a good quality 15 ounce box so your base is soft and flavorful
  • Peach Jell O: The secret to turbocharging the peach taste Grab the 3 ounce size boxes and look for the brightest color for the best visual pop
  • Eggs: Four eggs add richness and structure so the cake is sturdy enough for all those peaches
  • Oil: Light tasting olive oil is my favorite so the fruit shines There are good results with classic vegetable oil too
  • Frozen peaches: Use a quality brand with ripe fruit The bigger the slices the better the chunks in the final cake Do not thaw them first this keeps the texture firm
  • Salted butter: Use real butter not margarine for a frosting that has true creamy taste
  • Brown sugar: Packed tightly in your measuring cup This gives the frosting a caramel like depth Always use fresh soft brown sugar for smoothest results
  • Heavy cream: Look for thick fresh cream for best whip and richness in the frosting
  • Vanilla: Pure vanilla rounds out the flavors and adds complexity A little goes a long way
  • Ice water: will be used to cool the frosting fast so gather some ice cubes ahead

Step-by-Step Instructions

Make the batter:
Use a large mixing bowl or stand mixer to combine the cake mix peach Jell O eggs and oil. Beat until totally smooth and evenly mixed. The color should be bright and the batter thick
Prepare the peaches:
Take your bag of frozen sliced peaches and cut each piece in half for better bites. If using canned or fresh peaches pat them absolutely dry first. Fold the pieces gently into your batter using a sturdy spoon so the fruit does not break up too much
Bake the cake:
Pour the batter into a well greased nine by thirteen inch cake pan. Smooth out evenly and place in the preheated oven at 350 degrees F. Bake for around forty to forty five minutes. Check doneness with a toothpick. It is finished when there is no raw batter on the pick a few moist crumbs are fine. The edges will be nicely brown
Cool the cake:
Set your cake on a wire rack and let it cool completely. This is vital so the frosting goes on smoothly and does not melt
Make the frosting:
In a two quart pot combine the butter brown sugar and heavy cream. Place over medium high heat and stir gently as it melts together. Wait for a full rolling boil bubbles should cover the surface then set a timer for one minute stirring the whole time
Chill the frosting:
Remove the pot from heat and mix in the vanilla. Prepare an ice bath in a large bowl. Carefully place your pot into the bath making sure water does not get in the frosting. Let it cool until it thickens and is close to room temperature Scrape the edges of the pot so you do not miss any frosting
Whip the frosting:
Using a hand mixer beat the frosting for three to five minutes. It should look shiny smooth and still pourable but hold a ribbon when you lift the beater
Frost the cake:
Spread your gorgeous brown sugar frosting over the fully cooled cake, making sure to cover every corner. Let set at room temp or store as directed

Brown sugar is my secret weapon in dessert recipes. The smell alone when boiling the sugar and butter makes everyone hover in the kitchen. My little nieces always beg to lick the frosting beaters and I admit it is impossible to resist sneaking a spoonful.

Storage Tips

Keep this cake covered on the counter for up to two days but after that it needs the fridge to stay fresh. The frosting will firm up in the fridge but still taste incredible. If you want to freeze slices just wrap tightly and thaw at room temp so the texture stays moist.

Ingredient Substitutions

Fresh or canned peaches do work well if you drain them thoroughly and dry them with paper towels. If you want less sweetness try using unsweetened canned peaches. Peach Jell O can be swapped for orange Jell O if you need to improvise.

Serving Suggestions

This cake is sturdy enough to travel so take it to barbeques or picnics. Add a scoop of vanilla ice cream for a true southern style treat. Sometimes I cut it into squares and bring it out with coffee for brunch or afternoon snacks.

From Box Mix to Family Favorite

Peach cakes date back to southern kitchens where cooks made the most of fruit harvests. The Jell O and cake mix shortcut came about for busy home bakers but you can taste the care in every slice. I love that a humble box mix dessert ends up being the star of the table.

What You’ll Need to Make This

01 425 g yellow cake mix
02 170 g peach-flavoured gelatine dessert powder
03 4 large eggs
04 240 ml neutral vegetable oil
05 450 g frozen peaches, sliced, unthawed

→ Brown Sugar Frosting

06 115 g salted butter
07 400 g packed brown sugar
08 160 ml heavy cream
09 1 teaspoon vanilla extract

How to Prepare

Step 01

Preheat oven to 175°C. Grease a 23 x 33 cm baking pan to prevent sticking.

Step 02

In a large mixing bowl, combine cake mix, peach gelatine powder, eggs, and oil. Beat until smooth and fully incorporated.

Step 03

Slice frozen peach segments into bite-sized pieces without thawing. Gently fold peaches into the batter using a sturdy spoon.

Step 04

Transfer batter to prepared pan, spreading evenly. Bake for 40–45 minutes or until a toothpick inserted in the centre comes out with moist crumbs but no raw batter. Edges should be golden brown.

Step 05

Remove cake from oven and allow it to cool completely on a wire rack before frosting.

Step 06

In a medium saucepan, combine butter, brown sugar, and cream. Stir over medium-high heat until the mixture reaches a rolling boil across the surface. Boil for 1 minute, stirring frequently.

Step 07

Remove pan from heat and stir in vanilla extract. Prepare an ice bath in a large bowl. Set the saucepan with frosting into the ice bath, being careful not to allow water into the frosting. Cool until mixture thickens to room temperature, scraping the sides occasionally.

Step 08

Using a hand mixer, beat the cooled frosting 3–5 minutes until it increases in volume and becomes spreadable yet pourable.

Step 09

Spread frosting evenly over completely cooled cake. Serve at room temperature. For best freshness, cover and store leftovers in the refrigerator after one to two days.

Extra Tips

  1. For optimal texture, use frozen peaches directly from the freezer. Alternative options include well-drained canned or fresh peaches.
  2. Use light-flavoured olive oil or any neutral oil to avoid overpowering the cake’s peach notes.
