A Centerpiece with a Zesty Secret

Bundt cakes have always felt like the ultimate expression of home baking to me: sturdy, dependable, and universally loved. I decided to elevate my standard vanilla bundt one weekend by tunneling a bright, tart citrus filling straight through the middle.

The result was this incredible Lemon curd cake, which provides a beautiful surprise when you slice into it. It has since earned its place as a heavy hitter in my collection of Lemon desserts, perfect for when you want a bake that looks as impressive as it tastes.

Why This Bundt Will Win You Over

You are going to absolutely love this recipe because it combines the best of both worlds: a rich, tender cake and a gooey, tart center. Here is why it is a standout among Lemon Curd Recipes:

• The Hidden Tunnel: Every slice reveals a beautiful, bright ribbon of filling that cuts through the richness of the cake.
• Incredible Moisture: The addition of Greek yogurt to the batter ensures the cake stays wonderfully moist for days.
• Effortlessly Elegant: The bundt pan does all the hard work for you, creating a beautiful shape that requires minimal decoration.

Everything You Need

• 2 and 3/4 cups all-purpose flour: Spooned and leveled.
• 1 teaspoon baking powder: To give the dense cake a gentle lift.
• 1/2 teaspoon baking soda: Works with the yogurt for a tender crumb.
• 1 teaspoon salt: To balance the sweetness.
• 1 cup (2 sticks) unsalted butter: Softened to room temperature.
• 2 cups granulated sugar: To sweeten and tenderize the cake.
• 4 large eggs: Room temperature to ensure a smooth batter.
• 1 cup plain Greek yogurt: Also at room temperature; this adds incredible moisture and a slight tang.
• 1 tablespoon vanilla extract: For a warm, inviting flavor.
• 1 cup Lemon Curd: Thick store bought or homemade filling for the tunnel.

Crafting Your Cake

• STEP 1 – Very generously grease a 10 to 12 cup bundt pan with butter and dust it thoroughly with flour, tapping out the excess. Do not skip this step!
• STEP 2 – In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set the dry ingredients aside.
• STEP 3 – In a large mixing bowl, beat the softened butter and granulated sugar together on medium speed until very light and fluffy. This should take about 3 to 4 minutes.
• STEP 4 – Add the room temperature eggs one at a time, beating well after each addition and scraping down the sides of the bowl. Beat in the vanilla extract.
• STEP 5 – With the mixer on low speed, add the dry ingredients in three parts, alternating with the Greek yogurt in two parts. Begin and end with the flour mixture. Mix just until combined; do not overmix.
• STEP 6 – Spoon exactly half of the batter into the prepared bundt pan. Use the back of a spoon to create a deep, continuous trench in the center of the batter, all the way around the ring.
• STEP 7 – Carefully spoon the lemon curd into the trench, taking care to ensure it does not touch the sides or the center tube of the pan.
• STEP 8 – Gently spoon the remaining batter over the top, smoothing it out to completely encase the filling. Bake at 350 degrees Fahrenheit for 50 to 60 minutes, or until a skewer inserted (avoiding the curd center) comes out clean. Let the cake cool in the pan for exactly 15 minutes before inverting onto a wire rack.

Fun Twists and Serving Ideas

• Citrus Glaze: Once the cake is completely cool, drizzle a simple glaze made of 1 cup powdered sugar and 2 tablespoons fresh lemon juice over the top.
• Zesty Batter: Fold a tablespoon of fresh lemon zest into the batter along with the vanilla extract to boost the citrus flavor even further.
• Berry Compote: Serve generous slices with a spoonful of warm blueberry or blackberry compote on the side.
• Sugared Edges: While the cake is still warm from the oven, brush the outside very lightly with melted butter and dust it with granulated sugar for a sparkly, crunchy crust.

Pro Tips

• Prep the Pan Meticulously: Bundt pans are notorious for sticking. Take your time to butter every single crevice, and flour it generously.
• Keep the Filling Contained: It is crucial that the filling does not touch the edges of the pan. If it does, the sugar in the curd will burn and cause the cake to stick and tear when you invert it.
• Use Thick Filling: If your filling is too runny, it will simply bake into the batter rather than creating a distinct tunnel.
• Do Not Overmix: Once the flour is added, mix only until you no longer see streaks of white to keep the cake tender.
• Time the Cooling: Let the cake rest in the pan for exactly 15 minutes. If you try to turn it out too soon, it will fall apart. If you leave it too long, it will steam and stick to the pan.

Ingredients

  

Cake Batter

• 2 3/4 cups all-purpose flour spooned and leveled
• 1 tsp baking powder
• 1/2 tsp baking soda
• 1 tsp salt
• 1 cup unsalted butter 2 sticks, softened to room temperature
• 2 cups granulated sugar
• 4 large eggs room temperature
• 1 cup plain Greek yogurt room temperature
• 1 tbsp vanilla extract

Lemon Curd Filling

• 1 cup lemon curd thick, store-bought or homemade

Equipment

• 10 to 12-Cup Bundt Pan
• Electric mixer
• Mixing bowls
• Whisk
• Wire rack
• Pastry Brush

Method

 

1. Preheat the oven to 350°F (177°C). Generously grease a 10 to 12-cup Bundt pan with softened butter, making sure to cover every crevice, then dust thoroughly with flour. Tap out any excess.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. In a large mixing bowl, beat the softened butter and granulated sugar on medium speed for 3 to 4 minutes, until very light and fluffy.
4. Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl as needed. Beat in the vanilla extract.
5. With the mixer on low speed, add the dry ingredients in three portions, alternating with the Greek yogurt in two portions. Begin and end with the flour mixture. Mix just until combined, taking care not to overmix.
6. Spoon exactly half of the batter into the prepared Bundt pan. Use the back of a spoon to create a deep, continuous trench through the center of the batter, following the ring around the pan.
7. Carefully spoon the lemon curd into the trench. Keep the filling away from the sides of the pan and the center tube so it remains enclosed inside the cake.
8. Gently spoon the remaining batter over the lemon curd, spreading it evenly to cover the filling completely.
9. Bake for 50 to 60 minutes, or until a skewer inserted into the cake while avoiding the lemon curd center comes out clean.
10. Let the cake cool in the pan for exactly 15 minutes. Carefully invert it onto a wire rack and allow it to cool completely before slicing or glazing.

Notes

For extra citrus flavor, fold 1 tablespoon of fresh lemon zest into the batter with the vanilla. Once cooled, the cake can be drizzled with a glaze made from 1 cup powdered sugar and 2 tablespoons fresh lemon juice. Serve with warm blueberry or blackberry compote.

For a sparkly crust, lightly brush the outside of the warm cake with melted butter and dust with granulated sugar. Use thick lemon curd to help maintain a distinct filling tunnel, and avoid letting it touch the pan. Sour cream can replace Greek yogurt in equal amounts.

Store in an airtight container at room temperature for up to 4 days. To freeze, wrap the completely cooled, unglazed cake tightly in plastic wrap and aluminum foil; freeze for up to 3 months. Allow frozen cake to thaw before serving.

FAQs

Can I make this cake ahead of time? Yes, bundt cakes are incredibly sturdy and often taste better the next day as the flavors meld. Store it in an airtight container at room temperature for up to 4 days.

Can I use sour cream instead of Greek yogurt? Absolutely. Sour cream makes an excellent 1 to 1 substitute and provides the same level of moisture and tenderness.

Why did my filling sink to the bottom of the pan? This happens if the filling is too thin, or if the bottom layer of batter wasn’t thick enough. Make sure to use a thick filling and use exactly half the batter for the base layer.

Can I freeze this bundt cake? Yes! Wrap the completely cooled, unglazed cake tightly in plastic wrap, then in aluminum foil. It will freeze beautifully for up to 3 months.

Why did my cake stick to the pan even though I greased it? Sometimes cooking sprays don’t provide enough coverage for intricate bundt pans. Using softened butter applied with a pastry brush, followed by a dusting of flour, is the most reliable method.
