What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients that come together to create bold flavor and a satisfying texture without fuss. Most are pantry staples or easy to find in any grocery store.

• Peaches: 4-5 ripe but firm peaches, sliced (firmness helps them hold shape during caramelization)
• Unsalted Butter: 1/2 cup (113g), melted (adds richness and helps caramel develop)
• Brown Sugar: 3/4 cup (150g), packed (for that deep caramel flavor)
• All-Purpose Flour: 2 cups (250g), sifted (for a tender crumb; King Arthur flour works great here)
• Baking Powder: 2 tsp (provides lift)
• Salt: 1/2 tsp (balances sweetness)
• Granulated Sugar: 1 cup (200g) (to sweeten the cake itself)
• Large Eggs: 3, room temperature (for structure and moisture)
• Whole Milk: 3/4 cup (180ml), room temperature (adds moisture)
• Vanilla Extract: 2 tsp (pure vanilla for best aroma)
• Dark Rum: 1/4 cup (60ml) (for the rum glaze, imparts warmth and complexity)
• Powdered Sugar: 1 cup (120g) (to sweeten and thicken the glaze)

Tip: If you want a dairy-free version, swap milk for almond or oat milk and use a plant-based butter substitute. For a gluten-free take, almond flour can replace all-purpose flour, though the texture will be a bit denser.

Equipment Needed

• Bundt Pan: 10-inch size recommended for even baking and that signature shape. I’ve found the non-stick silicone versions make unmolding easier, but a well-greased metal pan works too.
• Mixing Bowls: One large for wet ingredients, one for dry — essential for smooth batter.
• Whisk and Spatula: For combining ingredients without overmixing.
• Measuring Cups and Spoons: Precise measurements matter here for consistent results.
• Small Saucepan: To gently melt butter and brown sugar and prepare the caramel base.
• Cooling Rack: To let the cake cool briefly before inverting — patience here prevents sticking.

For those on a budget, a standard metal bundt pan works perfectly well, just make sure to grease it thoroughly with butter and flour or non-stick spray. If you have a stand mixer, it can speed up the mixing process, but a hand whisk is just fine.

Preparation Method

1. Prepare the caramel base: In a small saucepan over medium heat, melt 1/2 cup (113g) unsalted butter. Once melted, stir in 3/4 cup (150g) packed brown sugar. Cook gently, stirring frequently, until the mixture bubbles and thickens slightly (about 4-5 minutes). Remove from heat.
2. Arrange the peaches: Pour the caramel mixture into your greased 10-inch bundt pan, spreading it evenly across the bottom. Arrange peach slices in a circular pattern atop the caramel, slightly overlapping them for a pretty presentation. Set aside.
3. Mix dry ingredients: In a large bowl, whisk together 2 cups (250g) sifted all-purpose flour, 2 tsp baking powder, and 1/2 tsp salt.
4. Combine wet ingredients: In another bowl, beat 1 cup (200g) granulated sugar with 3 large eggs until pale and slightly fluffy (about 2-3 minutes). Add 3/4 cup (180ml) whole milk and 2 tsp vanilla extract, mixing well.
5. Make the batter: Gradually add the dry ingredients to the wet mixture, folding gently to avoid overmixing. The batter should be smooth but slightly thick.
6. Pour batter over peaches: Carefully spread the batter over the arranged peaches in the bundt pan, smoothing the top with a spatula.
7. Bake: Place the bundt pan in a preheated oven at 350°F (175°C) and bake for 50-60 minutes. Check doneness by inserting a toothpick into the center — it should come out clean or with a few moist crumbs.
8. Cool and invert: Let the cake cool in the pan for 15 minutes. Then, place a serving plate upside down over the pan and carefully invert to release the cake. The peaches should glisten atop a caramelized crust.
9. Prepare the rum glaze: In a small bowl, whisk 1 cup (120g) powdered sugar with 1/4 cup (60ml) dark rum. Adjust consistency by adding more powdered sugar or rum as needed to get a pourable glaze.
10. Glaze and serve: Drizzle the rum glaze over the warm cake. Let it set for a few minutes before slicing and serving.

Pro tip: If your peaches are super juicy, pat them dry with a paper towel before arranging to prevent sogginess. Also, avoid opening the oven door too often during baking to keep the cake moist and tender.

Cooking Tips & Techniques

Getting that perfect caramelized peach upside down bundt cake with rum glaze requires a few tricks I picked up along the way. First, don’t rush the caramel base. Letting the butter and brown sugar bubble gently until thickened ensures a rich, silky coating that clings to the peaches beautifully.

When arranging the peaches, think of them like petals — overlapping slightly gives a stunning pattern once inverted. Using firm peaches is key; overly ripe ones tend to break down and create too much juice, which can make the cake soggy.

Also, folding the batter instead of vigorous stirring helps keep the crumb tender and not tough. I once overmixed and ended up with a dense cake — lesson learned! Baking in a bundt pan means the batter cooks evenly, but if you don’t have one, a 9×13-inch pan can work, though the caramelization won’t be quite the same.

Timing is everything. That 15-minute cooling period before flipping is crucial. If you try to unmold too soon, the caramel can stick to the pan and tear the topping. Lastly, the rum glaze is best made fresh and poured just before serving; it adds a subtle warmth that complements the peaches without overpowering them.

Variations & Adaptations

This caramelized peach upside down bundt cake with rum glaze is wonderfully versatile. Here are some ways to make it your own:

• Seasonal Twist: Swap peaches for nectarines or plums in late summer for a slightly different tang and sweetness.
• Non-Alcoholic Version: Replace dark rum with apple juice or a touch of vanilla extract in the glaze for a family-friendly option.
• Nutty Addition: Sprinkle toasted pecans or walnuts over the caramel before arranging peaches to add crunch and a toasty flavor.
• Spiced Cake: Add 1 tsp ground cinnamon and a pinch of nutmeg to the dry ingredients for a warm spice note that pairs beautifully with the fruit.
• Gluten-Free: Use a gluten-free baking mix in place of all-purpose flour, bearing in mind the texture will be slightly different but still delicious.

Personally, I’ve experimented with a version using bourbon instead of rum in the glaze, which gave a smoky depth that friends raved about. If you love Irish coffee tiramisu, you might appreciate that bourbon twist here too.

Serving & Storage Suggestions

This cake is best served slightly warm to enjoy the gooey caramel and fresh peach flavors at their peak. A dollop of whipped cream or a scoop of vanilla ice cream (like my no-churn strawberry ice cream) makes it even more indulgent.

Leftovers store well covered at room temperature for up to two days or in the refrigerator for up to four days. To reheat, pop individual slices in the microwave for 20-30 seconds or warm gently in the oven at 300°F (150°C) for about 10 minutes. The flavors actually deepen overnight, so it’s often even better the next day.

If you want to freeze, wrap slices tightly in plastic wrap and place in an airtight container for up to two months. Thaw in the fridge overnight and warm before serving.

Frequently Asked Questions

Can I use canned peaches instead of fresh peaches?

Fresh peaches are best for texture and flavor, but if you must, drain canned peaches well and pat dry before using to reduce extra moisture.

Dark rum adds the richest flavor, but spiced rum or aged rum also work nicely depending on your preference.

How do I prevent the cake from sticking to the bundt pan?

Grease the pan thoroughly with butter and flour, or use a non-stick spray designed for baking. Let the cake cool for about 15 minutes before inverting.

Can I make this cake ahead of time?

Yes! It actually tastes better the next day once the flavors meld. Just store it covered at room temperature or in the fridge.

Is it possible to make this recipe vegan?

With some substitutions—like flax eggs, plant-based butter, and dairy-free milk—you can adapt the recipe, but the texture and flavor will differ somewhat from the original.
