Ingredients

• 8 Tablespoons 1 stick unsalted butter, at room temperature
• 1 ¼ cups granulated sugar (divided using 1 cup for the batter and ¼ cup for the lemon syrup)
• 2 extra-large eggs (at room temperature)
• 2 Tablespoons + 2 tsp grated lemon zest
• 1 ½ cups flour
• ¼ teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon kosher salt
• 6 tbsp freshly squeezed lemon juice (divided, using 2 tsp in the batter and the remaining in the lemon syrup)
• 6 Tablespoons buttermilk (at room temperature)
• ½ teaspoon pure vanilla extract
• 5 ounces ½ cup rhubarb, finely chopped
• 5 ounces ½ cup canned tart cherries, drained and patted dry
• 1 cup confectioners’ sugar, sifted
• 1 tsp + 1-½ tsp freshly squeezed lemon juice

How to make Rhubarb-Cherry Lemon Cake

Step 1: First things first, let’s get everything ready. Adjust your oven rack to the middle position and preheat the oven to 350°F. Grease and flour a loaf pan well. For easy removal, you can also line the bottom with a strip of parchment paper. Make sure your butter, eggs, and buttermilk are at room temperature. Zest your lemons first, then juice them. If you’re using frozen rhubarb, let it thaw completely and pat it dry to get rid of extra water. Drain your canned cherries and pat them dry with a paper towel, too.

Step 2: In the bowl of your electric mixer with the paddle attachment, cream the room-temperature butter and 1 cup of the granulated sugar. Beat them together for about 5 minutes until the mixture is light, fluffy, and pale in color.

Step 3: With the mixer running on medium speed, add the eggs one at a time, making sure each one is fully incorporated before adding the next. Then, mix in the lemon zest until it’s fragrant and evenly distributed.

Step 4: In a medium bowl, sift or whisk together the flour, baking powder, baking soda, and kosher salt. In a separate small bowl or liquid measuring cup, combine 2 tablespoons of the lemon juice with the buttermilk and vanilla extract.

Step 5: Now it’s time to bring it all together. Add about one-third of the dry flour mixture to the butter and egg batter, mixing on low until just combined. Follow with about one-third of the wet buttermilk mixture. Continue alternating between the dry and wet ingredients, beginning and ending with the flour mixture. Be careful not to overmix!

Step 6: Gently fold the chopped rhubarb and drained cherries into the batter using a rubber spatula. Pour the finished batter into your prepared loaf pan and use the spatula to smooth the top.

Step 7: Bake for 50 to 55 minutes. You’ll know it’s done when a toothpick or cake tester inserted into the center of the cake comes out clean. The top will be golden brown and domed.

Step 8: While the cake is baking, prepare the lemon syrup. In a small saucepan, combine the remaining ¼ cup of granulated sugar with the remaining ¼ cup of lemon juice. Cook over low heat, stirring gently, just until the sugar has completely dissolved. Set it aside.

Step 9: Once the cake is out of the oven, let it cool in the pan on a wire rack for 10 minutes. Then, carefully remove the cake from the pan and place it directly on the wire rack. It’s a good idea to put a baking sheet under the rack to catch any drips. Slowly and evenly spoon the warm lemon syrup all over the top of the cake, letting it soak in.

Step 10: Let the cake cool completely, which will take about an hour. Once it’s cool, whisk together the sifted confectioners’ sugar and the final bit of lemon juice in a small bowl until you have a smooth, pourable glaze. Drizzle the glaze over the top of the cake, letting it drip artfully down the sides.

How to serve Rhubarb-Cherry Lemon Cake

This cake is an absolute star all on its own, served in thick slices with a cup of hot tea or coffee. The combination of tart fruit and bright lemon is perfectly refreshing for an afternoon treat. For a more decadent dessert, serve a slice slightly warmed with a dollop of fresh whipped cream, a scoop of vanilla bean ice cream, or a spoonful of crème fraîche to complement the sweetness.

How to store Rhubarb-Cherry Lemon Cake

To keep your cake fresh, store it in an airtight container at room temperature for up to 3 days. The lemon syrup soak helps it stay wonderfully moist. If you need to store it longer, you can refrigerate it for up to a week. The glaze may become slightly less crisp in the fridge, but the flavor will still be fantastic. For best results, let it come to room temperature before serving. You can also freeze the unglazed cake by wrapping it tightly in plastic wrap and then foil for up to 3 months.

Tips to make Rhubarb-Cherry Lemon Cake

• Room Temperature is Key: Don’t skip the step of bringing your butter, eggs, and buttermilk to room temperature. This ensures all the ingredients emulsify properly, creating a smooth, uniform batter and a tender final cake.
• Don’t Overmix: Once you start adding the flour, mix only until it’s just combined. Overmixing develops the gluten in the flour, which can lead to a tough, dry cake.
• Coat the Fruit: To help prevent the rhubarb and cherries from sinking to the bottom of the pan, you can toss them in a tablespoon of your dry flour mixture before folding them into the batter.
• Don’t Skip the Syrup: The lemon syrup soak is what takes this cake from good to great. It adds an extra layer of lemon flavor and guarantees an incredibly moist crumb.

FAQs About Rhubarb-Cherry Lemon Cake

Can I use fresh cherries instead of canned?
Absolutely! If you use fresh tart cherries, be sure to pit them and chop them. You’ll need about 1 cup of chopped fresh cherries to equal the 5 ounces of canned cherries.

What if I can’t find rhubarb?
If rhubarb isn’t in season, you can use frozen rhubarb; just be sure to thaw it and pat it very dry. You could also substitute it with another tart fruit like chopped cranberries or raspberries for a different but equally delicious twist.

Can I make this in a different pan?
Yes, you can adapt this recipe. For a round 8-inch or 9-inch cake, the baking time will likely be shorter, around 35-45 minutes. You could also make muffins or mini-loaves, but you’ll need to reduce the baking time significantly and start checking for doneness after about 20-25 minutes.

Final Thoughts

This Rhubarb-Cherry Lemon Cake is a true celebration of bright, fresh flavors. It’s the kind of homemade treat that feels both comforting and special. The tangy fruit, the zesty lemon, and the super moist texture come together to create a cake that you’ll want to make again and again. I hope you enjoy every last crumb!
