• 2 cups fresh rhubarb, diced: The star of the show, rhubarb adds bright tartness and vibrant color.
• 1/2 cup granulated sugar: Used to macerate the rhubarb and bring out its natural juices.
• 1 tablespoon lemon juice: Enhances the rhubarb’s freshness and prevents browning.
• 1/4 cup unsalted butter, melted (for topping): Creates a rich caramel base when combined with brown sugar and caramel sauce.
• 1/2 cup brown sugar, packed: Offers deep molasses notes that complement the caramel perfectly.
• 1/4 cup caramel sauce (store-bought or homemade): Adds luscious swirls of sweetness that melt into the cake.
• 1 1/2 cups all-purpose flour: The kitchen staple that forms the base of a soft cake.
• 1 teaspoon baking powder: Gives the cake a gentle lift to keep it light.
• 1/2 teaspoon baking soda: Works with sour cream to create a tender crumb.
• 1/4 teaspoon salt: Balances all the flavors beautifully.
• 1/2 cup unsalted butter, softened (for cake): Adds richness and moisture for the perfect cake texture.
• 2/3 cup granulated sugar: Sweetens the batter just right without overwhelming.
• 2 large eggs: Provide structure and bind everything together.
• 1 teaspoon vanilla extract: Infuses the cake with warm, comforting aroma.
• 1/2 cup sour cream: Keeps the cake moist and tender with a slight tang.
• 1/4 cup milk: Lightens the batter ensuring it bakes up soft and fluffy.

How to Make Upside-Down Rhubarb Cake with Caramel Swirls Recipe

Step 1: Prepare Your Pan and Rhubarb

Start by preheating your oven to 350°F (175°C). This ensures the perfect heat right from the get-go. Grease a 9-inch round cake pan thoroughly and line the bottom with parchment paper to help with easy removal later. Next, toss the diced rhubarb with 1/2 cup granulated sugar and lemon juice in a bowl. Letting it sit for about 15 minutes helps the rhubarb macerate, drawing out its juices and softening it slightly — this is key for that luscious texture and balanced tartness in the finished cake.

Step 2: Create the Caramel Base Layer

Pour the melted butter evenly into the bottom of the prepared cake pan. Sprinkle the brown sugar all over the butter, then drizzle the caramel sauce on top in a gentle back and forth motion. This simple yet important step forms a mouthwatering caramel layer that will melt into the rhubarb and cake as it bakes, giving you those irresistible caramel swirls.

Step 3: Add the Rhubarb

After macerating, drain any excess liquid from the rhubarb to prevent sogginess in your cake. Then spread the rhubarb evenly over the caramel layer in the pan. This tart, juicy layer is what makes the Upside-Down Rhubarb Cake with Caramel Swirls Recipe really stand out — it’s the beautiful topping that draws everyone in.

Step 4: Mix Dry Ingredients

In a separate mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Keeping these ingredients dry until now ensures they’re evenly distributed throughout your batter for consistent rise and texture.

Step 5: Cream Butter and Sugar

Using a stand mixer or hand mixer, cream the softened butter with 2/3 cup granulated sugar until the mixture becomes pale and fluffy — this process incorporates air, which means your cake will bake up light and tender. Next, add the eggs one at a time, beating well after each addition, followed by the vanilla extract for that warm, inviting aroma.

Step 6: Combine Wet and Dry Ingredients

Stir the sour cream and milk into the creamed mixture until just combined. Then gradually fold in the dry ingredients, mixing gently until the batter is smooth but not overworked. This balance is crucial to keep your cake tender but structured.

Step 7: Assemble and Bake

Carefully spread the batter over the rhubarb and caramel layer, smoothing out the top for even baking. Place the pan in your preheated oven, baking for 40 to 45 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean. The aroma by this point is absolutely divine, promising a gorgeous cake that’s as delicious as it looks.

Step 8: Cool and Invert

Allow the cake to cool in the pan for 10 minutes to set, then run a knife gently around the edges to loosen it. The exciting moment is here: invert the pan onto a serving plate to reveal the glossy rhubarb and caramel topping. Let the cake cool completely before slicing to let those caramel swirls settle beautifully.

How to Serve Upside-Down Rhubarb Cake with Caramel Swirls Recipe

Garnishes

To elevate this vibrant cake, consider topping each slice with a dollop of whipped cream or a scoop of vanilla ice cream. A sprinkle of toasted almonds or chopped pistachios adds a delightful crunch that contrasts wonderfully with the soft cake and caramel swirls. Fresh mint leaves also add a refreshing touch and a pop of green color.

Side Dishes

While this cake is a star all on its own, pairing it with a light, fruity compote or a fresh berry salad can enhance the experience. A cup of hot herbal tea or freshly brewed coffee also complements the warm, sweet, and tangy flavors, creating a perfect afternoon treat.

Creative Ways to Present

For a charming presentation, serve individual slices on rustic wooden boards or vintage plates, letting the caramel shine in natural light. You can drizzle additional caramel sauce over the top or sprinkle a touch of flaky sea salt for a sophisticated sweet-salty twist. This dessert also makes a show-stopping centerpiece for brunch or a special occasion.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, store the Upside-Down Rhubarb Cake with Caramel Swirls Recipe in an airtight container at room temperature for up to two days. For longer freshness, refrigerate it for up to 4 days. Make sure to bring it to room temperature before serving to restore that perfect texture.

Freezing

This cake freezes beautifully! Wrap it tightly in plastic wrap and then foil to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the fridge and bring to room temperature before serving to best preserve the caramel swirls and rhubarb flavor.

Reheating

To bring your leftover or thawed Upside-Down Rhubarb Cake with Caramel Swirls Recipe back to life, warm individual slices in the microwave for about 15 to 20 seconds or in a preheated oven at 300°F (150°C) for 8 to 10 minutes. This nicely softens the cake and revives the caramel without melting it away.

FAQs

Can I use frozen rhubarb for this recipe?

Yes, you can substitute frozen rhubarb if fresh is unavailable. Just be sure to thaw and drain any excess liquid well before macerating it to avoid excess moisture in the cake batter.

Is it possible to make homemade caramel sauce for this cake?

Absolutely! Homemade caramel sauce with butter, sugar, and cream adds a personal touch and can make this Upside-Down Rhubarb Cake with Caramel Swirls Recipe even more special. Just ensure it’s cooled before drizzling over the butter and brown sugar.

Can I swap sour cream for yogurt?

You can use Greek yogurt as a substitute for sour cream, which will add tanginess and moisture. Just keep the quantity the same to maintain the texture of the cake.

What if I don’t have a round pan?

A square or rectangular pan can work in a pinch. Just remember that baking times may vary slightly, so watch for the toothpick test to tell when the cake is done.

How do I prevent the caramel from sticking to the pan?

Greasing the pan thoroughly and lining the bottom with parchment paper will help prevent sticking and allow for easy inversion. Let the cake cool slightly before flipping so the caramel sets and releases smoothly.
