Ingredients & Equipment

Ingredients

2 cups all-purpose flour
1 1/2 cups granulated sugar
1/2 cup brown sugar (for the batter)
1/2 cup unsalted butter, softened
3 large eggs
1 cup milk
2 teaspoons baking powder
1 teaspoon vanilla extract
1/2 teaspoon salt
4 cups fresh peaches, sliced (about 4–6 medium peaches, depending on size)
1 cup brown sugar (for the icing)
1/2 cup heavy cream (for the icing)
1/4 cup unsalted butter (for the icing)

Equipment

9×13 inch baking pan
Mixing bowls (one large, one medium)
Electric mixer or stand mixer (hand mixing works, but a mixer speeds creaming)
Whisk
Spatula
Measuring cups and spoons
Knife and cutting board for slicing peaches
Saucepan for the caramel icing
Cooling rack
Toothpick or cake tester

Notes and helpful tools

Use ripe but firm peaches so they hold their shape in the batter.
If peaches are very juicy, briefly pat slices dry to avoid a soggy cake.
A bench scraper or offset spatula helps smooth the batter into the pan evenly.
A thermometer isn’t necessary, but an instant-read thermometer can check that the cake’s center reaches about 200°F if you prefer precision.
For a smoother batter, briefly pulse peaches in a blender for a chunky puree (see variations below). If you enjoy maple and brown sugar pairings in baked treats, the spice and sugar profile is similar to some of my favorite muffins—like these maple-brown sugar oatmeal muffins.

Step-by-Step Instructions (with tips)

Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. Tip: For easier cleanup and a prettier slice, line the pan with parchment and leave a little overhang on the long sides to lift the cake out once cooled.
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Tip: Creaming well (about 3–5 minutes with an electric mixer) incorporates air for a lighter cake. Scrape down the bowl halfway through.
Add eggs one at a time, mixing well after each addition. Tip: Room-temperature eggs incorporate more smoothly; if your eggs are cold, drop them into a bowl of warm water for a few minutes.
Stir in the vanilla extract. A good-quality vanilla makes a difference in a simple cake like this.
In another bowl, whisk together the flour, baking powder, and salt. Tip: Sifting isn’t required, but whisking helps distribute the baking powder and prevents little pockets of flour.
Gradually add the dry ingredients to the creamed mixture alternately with the milk, beginning and ending with the dry ingredients. Mix just until combined—overmixing develops gluten and can make the cake tough. A typical rhythm is: 1/3 dry, 1/2 milk, 1/3 dry, 1/2 milk, finish with remaining dry.
Gently fold in the sliced peaches. Tip: Use a soft rubber spatula and fold only until peaches are evenly distributed. If your peaches are very ripe and soft, you can toss the slices in a tablespoon of flour to help suspend them in the batter.
Pour the batter into the prepared baking pan and smooth the top. If desired, arrange a few extra peach slices on top for an attractive finish.
Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean. Tip: If the top browns too quickly, loosely tent with foil for the last 10 minutes. For an ultra-moist center, check at 32 minutes and test every few minutes afterward.
While the cake is baking, prepare the brown sugar caramel icing. In a saucepan, combine brown sugar, heavy cream, and butter. Cook over medium heat, stirring until the mixture comes to a boil and thickens slightly. Tip: Bring to a gentle boil and simmer for 1–2 minutes; it will thicken as it cools. If you want a pourable glaze, remove a touch earlier; for a thicker caramel sauce, simmer a little longer but watch carefully to prevent burning.
Once the cake is done, allow it to cool for a few minutes before icing it with the warm caramel icing. Tip: Pour slowly and use an offset spatula to coax sauce to the edges. The warm icing will sink into the top slightly and create a sticky, wonderful finish.
Allow the cake to cool completely before serving. This helps the icing set so slices hold together. Tip: If you prefer the icing to glaze into the cake more, you can prick the cake surface lightly with a skewer before pouring the warm caramel.

Variations and flavor suggestions

Roasted peaches: For intensified flavor, toss peach slices with a tablespoon of brown sugar and roast at 400°F for 10–12 minutes before folding into the batter. Roasting caramelizes the fruit and concentrates sweetness.
Pureed peaches: Pulse half the peaches in a blender until chunky and fold into batter for a marbled peach texture.
Spices: Add 1/2 teaspoon cinnamon and a pinch of nutmeg to the dry ingredients for warm spice notes.
Nuts: Fold in 1/2 cup toasted pecans or almonds for crunch.
Boiling vs. roasting: Boiling peaches isn’t recommended, as it makes them too soft for the batter; roasting or folding in fresh or lightly blanched slices preserves texture and flavor.
Vegan adaptation: Substitute butter with vegan butter, milk with plant milk, and use a flax "egg" (1 tablespoon ground flax + 3 tablespoons water per egg), though texture will change slightly.

Storage, Freezing & Make-Ahead Tips

Short-term storage

Room temperature: Store leftovers covered at room temperature for up to 2 days. Keep the cake in an airtight container or tightly wrapped to preserve moisture.
Refrigerator: For longer freshness (especially in warm climates or when iced), store covered in the refrigerator for up to 5 days. Note that refrigeration can firm the cake; bring to room temperature before serving for the best texture.

Freezing

To freeze individual slices: Wrap each cooled slice tightly in plastic wrap, then place in a freezer bag or container. Freeze for up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours.
To freeze the whole cake: Cool completely, then wrap the pan tightly in plastic wrap and foil. If you used parchment, you can lift the whole cake out and wrap it for better protection. Freeze up to 3 months. Thaw overnight in the refrigerator.

Make-ahead ideas

Bake the cake a day ahead and store it uniced in an airtight container; add the caramel icing just before serving to preserve the fresh, gooey topping.
Prepare the caramel sauce ahead, cool and refrigerate, then reheat gently on the stove, stirring until pourable. For smoother reheating, add a tablespoon of cream if it’s too thick.

Portioning advice

A 9×13 cake yields about 12 generous slices or 16 smaller portions for dessert-sized servings.
For parties, cut smaller squares and serve with a scoop of vanilla ice cream and a drizzle of extra caramel.

How to Use / Serve This Dish

Serving ideas

Classic: Serve slices warm or room temperature with a scoop of vanilla ice cream and a dusting of cinnamon.
Brunch: Top a slice with Greek yogurt and a drizzle of honey for a late-morning treat.
Coffee pairing: The caramel and peach sweetness pairs beautifully with medium-roast coffee or a milky latte.
Dessert plate: Add a dollop of whipped cream and a few extra pan-seared peach slices for an elegant presentation.

Creative variations

Peach upside-down twist: For a different look, layer peaches on the bottom of the pan with a touch of butter and brown sugar, then pour batter on top and bake—flip after cooling for a caramelized top.
Mini cakes or cupcakes: Divide batter into lined muffin tins and bake for 18–22 minutes for portable treats; reduce icing amount slightly for individual portions.
Layer cake: Use this batter in two 8- or 9-inch round pans for a layered peach cake, sandwiching extra caramel or whipped cream between layers.

Tips for warm-weather entertaining

Serve the cake chilled with a citrusy cocktail or iced tea; the cold temperature refreshes and balances the caramel’s richness.
Use the cake as a base for a trifle: cube leftover cake and layer with custard, whipped cream, and fresh peaches for an easy, make-ahead dessert.

For creative recipe mash-ups and texture ideas, I often borrow techniques from quick breads and bars—try using methods from a denser quick-bread approach like the one used in this banana bread brownies recipe to experiment with a fudgier texture in a smaller pan.

FAQ

Q: Can I use canned or frozen peaches?
A: Yes. If using canned peaches, drain them well and pat dry to prevent excess moisture. For frozen peaches, thaw and drain thoroughly; toss with a tablespoon of flour if very juicy. Note: Fresh peaches give the best texture and flavor, but canned or frozen work in a pinch.

Q: How long will this cake keep at room temperature?
A: Left un-filled and un-iced, the cake will keep at room temperature for up to 2 days in an airtight container. With the caramel icing, it’s safer to refrigerate, especially in warm or humid conditions, and it will keep 3–5 days chilled.

Q: Can I make this gluten-free?
A: Swap the all-purpose flour for a 1:1 gluten-free flour blend that includes xanthan gum. Texture may vary slightly, but many 1:1 blends work well. Bake time may be similar—watch for doneness with a toothpick.

Q: I don’t have heavy cream for the icing—what can I use?
A: You can substitute half-and-half, warm whole milk, or a dairy-free cream alternative, but the icing will be a bit thinner and less rich. To thicken, simmer slightly longer or add a tablespoon of corn syrup to help the glaze set.
