Brown Butter Peach Upside Down Cake

This brown butter peach upside down cake combines a rich, nutty sponge with a caramelized fruit topping. It is an ideal dessert for late summer when peaches are at their peak ripeness and flavor.

List of ingredients

• 1/2 cup sugar (100g) – used for the caramel base.
• 1/4 cup water – used to dissolve the sugar for the caramel.
• 1 large skin-on peach, thinly sliced – ensures the fruit layer stays intact.
• 10 tablespoons butter – to be browned for a deeper, nutty flavor.
• 3/4 cup granulated sugar (150g) – for the cake batter sweetness.
• 2 eggs, at room temperature – helps maintain batter emulsion.
• 1 teaspoon vanilla extract – enhances the natural peach aromatics.
• 1 cup all purpose flour (120g) – the structural base of the cake.
• 1 1/2 teaspoons baking powder – provides the necessary lift.
• 1/2 cup milk (2%) – adds moisture to the final crumb.
• Pinch of salt – balances the sweetness of the caramel and cake.
• Pinch of cinnamon – optional but adds warmth to the batter.

step-by-step instructions

1. Brown the butter: Melt the butter in a small saucepan over medium heat until it foams and turns an amber color. Pour it into a heat-safe bowl and chill in the fridge or freezer until it reaches room temperature and is pliable.
2. Prepare the pan: Grease an 8-inch cake pan with butter and line the bottom with a parchment paper disc. Arrange the thinly sliced peaches in a circular pattern across the bottom of the pan. Preheat your oven to 350°F.
3. Create the caramel: Combine 1/2 cup sugar and 1/4 cup water in a saucepan. Heat the mixture without stirring, only swirling the pan, until it reaches a light amber shade. Immediately pour the hot caramel over the arranged peaches in the pan.
4. Mix dry ingredients: In a small bowl, whisk together the all-purpose flour, baking powder, salt, and cinnamon. Set this mixture aside for later use.
5. Cream butter and sugar: Use a stand mixer with a paddle attachment to cream the room-temperature browned butter and granulated sugar. Process for at least 4 minutes until the mixture is pale, fluffy, and aromatic.
6. Add wet ingredients: Incorporate the eggs one at a time, scraping down the sides of the bowl after each addition. Stir in the vanilla extract until fully blended.
7. Combine batter: Mix in half of the flour mixture on low speed, then stir in the milk until no longer sloshy. Finally, add the remaining flour mixture and mix only until combined to avoid overworking the gluten.
8. Bake: Pour the batter over the peaches and caramel, smoothing the top with an offset spatula. Bake at 350°F for 40 minutes or until a toothpick inserted in the center comes out clean and the cake springs back.
9. Cool and invert: Allow the cake to cool in the pan for 10 minutes. Place a platter over the top and carefully invert the cake to reveal the peach topping. Serve warm or at room temperature.

Practical Baking Guidance

Select Firm Peaches for Better Slicing

Choose peaches that are ripe but still firm to the touch. Overly juicy peaches are difficult to slice into the thin, consistent pieces needed for the circular pattern. Skin-on peaches are recommended to help the slices hold their shape during the baking process.

Precision in Flour Measurement

Weighing flour with a digital scale is more accurate than using measuring cups. Too much flour can lead to a dry, dense cake, while too little may cause the cake to collapse. Using 120g for one cup ensures a consistent, moist crumb every time.

Maintain Room Temperature Ingredients

Ensure your eggs and milk are at room temperature before mixing. Cold eggs can cause the creamed butter to seize and the batter to curdle. Room temperature ingredients emulsify more effectively, resulting in a smoother batter and a more even rise.

Proper Brown Butter Technique

When browning butter, keep a close eye on the pan as it can go from amber to burnt very quickly. The butter will sputter and pop as the water evaporates, which is normal. Once the milk solids turn brown and smell nutty, remove it from the heat immediately.

Caramel Management Tips

Preventing Sugar Crystallization

To avoid clumpy caramel, whisk the sugar and water together before placing the pan on the heat. Once the heating process begins, do not stir the mixture with a spoon, as this introduces crystals that can cause the whole batch to grain. Only swirl the pan gently to distribute the heat.

Monitoring Caramel Color

Stop the cooking process as soon as the caramel reaches a light amber shade. Cooking the sugar to a dark amber may seem appealing, but it often results in a bitter taste that overpowers the sweetness of the peaches. The residual heat will continue to cook the sugar for a short time after removal.

Handling Hot Caramel

Caramel reaches extremely high temperatures and can cause severe burns. Pour it carefully and slowly over the fruit layer. Use a saucepan with a pour spout if available to ensure the caramel is distributed evenly without splashing.

Fruit and Dairy Substitutions

Alternative Fruit Options

If peaches are out of season, this method works well with other stone fruits or tropical fruits. Sliced pineapple rings or thinly sliced apples are excellent alternatives. Apricots also pair well with the brown butter flavor profile of the cake.

Milk and Cream Variations

While 2% milk is the standard for this recipe, whole milk can be used for a slightly richer taste. For a tangier crumb, substitute the milk with buttermilk, though you may need to add a pinch more baking soda to balance the acidity.

Sugar Alternatives in the Batter

Granulated sugar provides a light, fluffy texture, but light brown sugar can be used for a deeper molasses flavor. If using brown sugar, ensure it is packed firmly for measurement, but be aware that the cake may become slightly denser.

Serving and Presentation Ideas

Temperature Preferences

This cake is versatile and can be served warm, at room temperature, or chilled. Serving it warm emphasizes the gooey nature of the caramel and the softness of the peaches. Room temperature allows the buttery flavors of the sponge to become more prominent.

Complementary Toppings

A dollop of unsweetened whipped cream provides a light contrast to the rich caramel. A scoop of vanilla bean ice cream is a classic pairing that melts slightly into the warm cake. For a more sophisticated presentation, add a sprig of fresh mint for color.

Platter Selection

Use a wide, flat platter for inverting the cake to ensure the caramel does not run off the edges. A ceramic or glass plate works best as it can handle the heat of the cake without warping. Avoid using plates with high rims that might obstruct the inversion process.

Storage and Preservation

Room Temperature Storage

Store the cake in an airtight container at room temperature for up to three days. Keeping it out of the fridge helps maintain the soft texture of the sponge. Ensure the cake is completely cooled before sealing the container to prevent condensation.

Refrigeration Guidelines

If your kitchen is very warm, the cake can be stored in the refrigerator for up to five days. Note that refrigeration can firm up the butter in the cake, making the sponge feel denser. Always allow the cake to come back to room temperature before serving.

Freezing the Cake

This cake can be frozen by wrapping individual slices in plastic wrap and placing them in a freezer-safe bag. It will keep for up to two months. Thaw slices in the refrigerator overnight before reheating.

Reheating Instructions

Oven Reheating Method

To restore the cake to its original texture, heat individual slices in a 300°F oven for 5 to 8 minutes. This gently warms the caramel and softens the brown butter sponge without overcooking the fruit. Place the slice on a small piece of parchment paper to prevent sticking.

Microwave Reheating Method

For a quicker option, microwave a slice on medium power for 15 to 20 seconds. Be careful not to overheat, as the sugar in the caramel can become extremely hot and cause burns. This method is best for a softer, more pudding-like consistency.

Make-Ahead Planning

Advanced Butter Preparation

The brown butter can be prepared up to 24 hours in advance. After browning and cooling, store it in an airtight container in the refrigerator. Bring it back to room temperature for 30 minutes before creaming it with the sugar.

Prepping the Pan

You can arrange the peaches and pour the caramel into the pan a few hours before baking. Keep the pan covered and refrigerated until you are ready to pour the batter over the top. This allows the peaches to slightly marinate in the caramel.

Troubleshooting Common Issues

Managing a Stuck Cake

If the cake does not release from the pan immediately upon inverting, do not force it. Briefly warm the bottom of the pan over a low stove burner for 30 seconds to melt the caramel. This usually loosens the cake enough for it to slide out smoothly.

Addressing Batter Curdling

If the batter looks curdled after adding eggs, it is usually due to a temperature difference. Continue mixing on medium speed for another minute to bring the emulsion back together. Sifting in a small amount of the flour can also help stabilize the mixture.

Fixing a Sinking Center

A sinking center often occurs if the oven door is opened too frequently or if the baking powder is expired. Ensure the oven is fully preheated and avoid opening the door until at least 30 minutes of baking have passed. Use fresh baking powder for maximum lift.

Frequently Asked Questions

Can I use a springform pan?

Yes, a springform pan works well for this recipe. However, because the caramel is liquid, it can seep through the bottom. Wrap the bottom of the pan in aluminum foil or use a parchment disc to prevent leakage.

Why is my caramel clumpy?

Clumping is usually a sign of crystallization. This happens if the sugar is stirred while heating. To prevent this, only swirl the pan and ensure you whisk the water and sugar together before applying heat.

Can I use frozen peaches?

Frozen peaches can be used, but they must be completely thawed and patted dry with paper towels first. Excess moisture from frozen fruit can make the bottom of the cake soggy and dilute the caramel.

Is the cinnamon necessary?

Cinnamon is optional but highly recommended as it complements the nuttiness of the brown butter. If you prefer a cleaner peach flavor, you can omit it without affecting the cake’s structure.
