Bourbon Peach Upside-Down Cake
There's something magical about flipping a cake over to reveal a glossy, caramel-drenched carpet of peaches that makes home cooks swoon every time. This Bourbon Peach Upside-Down Cake is the epitome of summer in dessert form - warm cinnamon dances with bourbon's smoky depth, while almond flour lends a tender crumb that's sturdy enough to hold the peaches without sinking. It's perfect for impromptu picnics, Sunday suppers, or even as a show-stopping finish to a holiday meal. The aroma alone will have everyone crowding into the kitchen before the first slice is served.
What Makes This Recipe Special
- Almond flour adds delicate nuttiness and structure, balancing the fruit's juiciness without making the cake dense - a clever trick for moist, tender crumb.
- Bourbon isn't just a flavor note - it's infused into the caramel layer and batter, adding layers of vanilla, oak, and spice that deepen with every bite.
- Peaches are arranged skin-on to hold their shape and prevent sogginess, yet they soften just enough during baking to meld into the caramel syrup.
- The upside-down method ensures the peaches stay beautifully intact and evenly distributed, making every slice a vibrant, syrupy masterpiece.

Instructions
1
Preheat the oven to 350°F (175°C). Line a 9-inch cake pan (not a springform) with parchment paper and butter the paper.
2
Arrange the peach wedges over the parchment, starting at the center and working outward. Sprinkle 1/4 teaspoon cinnamon over the peaches.
3
Combine 1/4 cup water with 1/2 cup sugar in a saucepan. Stir to combine, then heat over medium-high heat without stirring until the mixture turns light brown, about 10-15 minutes. Remove from heat, add 1 tablespoon bourbon, and pour the caramel evenly over the peaches.
4
Using a mixer, beat the butter and 3/4 cup sugar together until light and fluffy (about 3 minutes). Beat in the eggs one at a time. Mix in the vanilla and 2 tablespoons bourbon.
5
In a separate bowl, whisk together the all-purpose flour, almond flour, baking powder, and remaining 1/4 teaspoon cinnamon. Slowly add the dry ingredients into the wet mixture, beating until combined.
6
Pour the cake batter over the peaches, smoothing the surface. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7
Let the cake cool in the pan for 15-30 minutes, then turn it out onto a serving dish.
Essential Tips
Peach prep
Use slightly underripe peaches for structure; they'll soften during baking but won't turn mushy. Slice them 1/2-inch thick for consistent caramel coverage and even cooking.
Caramel timing
Watch the caramel closely once it starts bubbling - it can go from golden to burnt in seconds. Remove it from heat as soon as it reaches a deep amber color, then immediately pour over the peaches.
Room-temperature eggs
Beat the eggs into the butter-sugar mixture one at a time, ensuring they emulsify fully for a light, airy batter that rises evenly around the peaches.
Flour blend trick
Sift the all-purpose and almond flour together with the baking powder and cinnamon to prevent clumps and ensure even distribution throughout the batter.
Baking check
Start checking for doneness at 30 minutes - the cake is done when the top is golden and a toothpick inserted in the center comes out clean, but the edges shouldn't be over-browned.
Smart Swaps & Variations
Gluten-free
Replace all-purpose flour with a 1:1 gluten-free baking flour blend and add 1/2 teaspoon xanthan gum to maintain structure.
Nut-free
Omit the almond flour and replace it with an additional 1/4 cup all-purpose flour for a lighter texture.
Spiced bourbon
Steep 1 cinnamon stick and 2 whole cloves in the bourbon for 10 minutes before using to infuse warm spice notes.
What to Serve With This
- Warmly spiced vanilla ice cream or bourbon-infused whipped cream to soak up the caramel.
- Fresh mint leaves scattered over the cake for a bright contrast to the sweet, boozy depth.
- A chilled glass of sparkling rosé or a bourbon old-fashioned to echo the cake's flavors.
- Greek yogurt drizzled with honey for a lighter, tangy counterpoint to the rich cake.
Storage & Reheating
Storage
Store the cake in the pan, covered with foil or a cake dome, at room temperature for up to 2 days. Refrigerate for up to 5 days if the kitchen is warm or to preserve freshness longer.
Reheating
Reheat individual slices in a 300°F (150°C) oven for 5-7 minutes to revive the caramel without making the cake soggy. Avoid microwaving - it turns the texture rubbery.
Expert Chef Tips
- Chill the cake batter for 20 minutes before baking to relax the gluten and prevent tunneling around the peaches.
- Use a high-quality, small-batch bourbon with vanilla and caramel notes - subtle bourbon flavor shines best in this cake.
- Brushing the peaches with a tiny bit of bourbon just before baking intensifies the fruit's natural sugars and adds another layer of aromatic depth.
Equipment You’ll Need
- 9-inch metal cake pan (not springform)
- Heavy-bottomed saucepan (for caramel)
- Stand mixer or hand mixer (for butter-sugar-egg mixture)
- Fine-mesh sieve (for sifting dry ingredients)
Nutritional Benefits
- Each slice provides about 320 calories, with natural fruit sugars from peaches and moderate added sugar for caramelization.
- Almond flour adds heart-healthy monounsaturated fats and a dose of vitamin E, while contributing to a lower glycemic index than all-purpose flour alone.
- Bourbon offers antioxidants from aging in oak barrels, though moderation is key - one slice delivers the flavor without excessive alcohol content.
- Peaches are rich in vitamin C and beta-carotene, supporting immune function and skin health, making this dessert a sneaky way to get fruit into your diet.

Frequently Asked Questions
Can I use canned peaches instead of fresh?
Fresh peaches are best for texture and flavor, but if using canned, drain them well and pat dry. Canned peaches may release excess liquid, so reduce the caramel water by 2 tablespoons to prevent a soggy cake.
What's the best pan to use?
Use a 9-inch metal cake pan (not glass or springform) for even heat distribution. A slightly dark pan will caramelize the peaches more deeply, but a light one works too - just extend baking time by 2-3 minutes if needed.
Can I make this cake ahead?
Yes! Assemble the cake up to the baking step and refrigerate, covered, for up to 8 hours. Bake straight from the fridge, adding 3-5 minutes to the baking time. Do not flip until ready to serve.
How do I handle a sticky flip?
Run a thin metal spatula around the edges of the pan before flipping to loosen any stuck bits. Place the serving plate firmly on top and invert with confidence - the caramel syrup should release easily if the cake is fully cooled.
Can I substitute another fruit?
Yes, but choose firm fruits like pears, plums, or nectarines. Halve or quarter them to match peach size, and adjust baking time as needed - firmer fruits may need 5-7 minutes longer.
Why did the cake sink in the middle?
This usually happens if the oven door was opened too early or the batter was undermixed. Ensure the eggs are fully incorporated and resist the urge to open the oven before the 25-minute mark.
Is there a non-alcoholic version?
Replace bourbon with peach nectar or apple cider, reducing other liquids by 1 tablespoon to maintain batter consistency. Add 1/2 teaspoon almond extract for depth if desired.
Can I freeze the cake?
Yes, freeze the fully cooled cake (unflipped) in the pan, wrapped tightly in plastic and foil, for up to 2 months. Thaw overnight in the fridge, then flip, reheat, and serve.
