Ingredients

• 1 ½ cups granulated sugar, divided
• 1 teaspoon ground cinnamon
• 1 ½ cups all-purpose flour
• 1 teaspoon baking soda
• ¼ teaspoon salt
• 1 cup buttermilk
• ¼ cup vegetable oil
• 1 large egg
• 1 teaspoon vanilla extract
• 2 cups chopped fresh rhubarb (about ½-inch pieces)

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
2. In a small bowl, combine ½ cup of the granulated sugar with the ground cinnamon. Set aside. This will be sprinkled over the top.
3. In a large mixing bowl, whisk together the all-purpose flour, the remaining 1 cup of granulated sugar, baking soda, and salt.
4. In a separate medium bowl, whisk together the buttermilk, vegetable oil, egg, and vanilla extract until well combined.
5. Pour the wet ingredients into the dry ingredients and mix with a spoon or spatula until just combined. Be careful not to overmix; a few lumps are okay.
6. Gently fold in the chopped fresh rhubarb.
7. Pour the batter evenly into the prepared baking pan.
8. Evenly sprinkle the reserved cinnamon-sugar mixture over the top of the batter.
9. Bake for 35-45 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean.
10. Allow the cake to cool in the pan on a wire rack before slicing and serving.

Expert Tips / Pro Tips

For the best results, ensure your rhubarb is fresh and firm. If your rhubarb is very tart, you can increase the amount of sugar in the batter by a tablespoon or two, but the cinnamon-sugar topping also adds a lovely sweetness that balances it out. Do not overmix the batter, as this can lead to a tougher cake; mix only until the ingredients are just combined. If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to a measuring cup, then filling the rest of the cup with regular milk and letting it sit for 5 minutes before using.

Variations & Substitutions

Feel free to get creative with this recipe! You can add ½ cup of chopped walnuts or pecans to the batter for a delightful nutty crunch. A teaspoon of grated orange zest or lemon zest can brighten the flavor profile beautifully. If you don’t have rhubarb, sliced apples or berries can be used as a substitute, though the baking time might vary slightly. For an extra touch of decadence, a simple cream cheese frosting would complement this cake wonderfully.

Serving Suggestions

This Moist Rhubarb Cake is absolutely delicious on its own, but it truly shines with a few simple additions. Serve a warm slice with a scoop of vanilla ice cream, a dollop of freshly whipped cream, or a drizzle of crème anglaise. A light dusting of powdered sugar just before serving also adds an elegant touch and a touch more sweetness. For a delightful breakfast or brunch treat, enjoy it with a cup of coffee or tea.

Storage, Freezing & Reheating

Store any leftover Moist Rhubarb Cake tightly covered at room temperature for up to 2-3 days, or in the refrigerator for up to 5 days. To freeze, wrap individual slices or the entire cooled cake tightly in plastic wrap, then an additional layer of aluminum foil. It can be frozen for up to 3 months. Thaw frozen cake in the refrigerator overnight or at room temperature for a few hours. To reheat, warm individual slices in the microwave for 15-30 seconds, or in a preheated oven at 300°F (150°C) for about 10-15 minutes, until just warmed through.

FAQ

Can I use frozen rhubarb?

Yes, you can use frozen rhubarb. Do not thaw it before adding it to the batter; add it directly from the freezer. You may need to add a few extra minutes to the baking time as frozen rhubarb releases more moisture.

Why is my rhubarb cake dry?

A dry cake is often a result of overmixing the batter or overbaking. Ensure you mix only until the ingredients are just combined and bake only until a toothpick comes out clean, but not overly dry.

Can I make this cake gluten-free?

While this recipe hasn’t been specifically tested with gluten-free flour, you can likely substitute a 1:1 gluten-free all-purpose baking blend that contains xanthan gum. Results may vary slightly in texture.

How can I make sure the rhubarb doesn’t sink to the bottom?

To help prevent rhubarb from sinking, you can lightly toss the chopped rhubarb in a tablespoon or two of the flour mixture before folding it into the batter. This creates a thin coating that helps it suspend more evenly.
