Equipment

• Small saucepan

Instructions

Creating this Tasty Rhubarb Cake is straightforward with these step-by-step instructions.

Rhubarb Cake with Streusel

First, preheat your oven to 350°F (175°C). Lightly grease and flour your 9×9 or 9×13 inch baking pan, or line with parchment paper for easy removal.

In a large mixing bowl, whisk together the oil, 1 cup granulated sugar, buttermilk, egg, and 1 teaspoon vanilla extract until the mixture is smooth and well combined.

Next, add the 2 cups all-purpose flour, baking powder, baking soda, and salt to the wet ingredients. Stir everything gently with a spoon or spatula until just combined. Be careful not to overmix; a few lumps are fine.

Fold in the 4 cups of chopped rhubarb until evenly distributed throughout the batter. Pour the batter into your prepared baking pan and spread it out evenly with your spatula.

Now, prepare the streusel topping. In a small bowl, combine the ¼ cup all-purpose flour, ¼ cup granulated sugar, and 2 tablespoons melted butter. Mix these ingredients with a fork until crumbly.

Generously sprinkle the streusel topping over the entire surface of the cake batter in the pan.

Bake the Tasty Rhubarb Cake for 45-60 minutes in the preheated oven, or until it’s golden brown on top and cooked through. A toothpick inserted into the center should come out clean. Baking time may vary based on your oven and pan size.

Let the cake cool in the pan on a wire rack for at least 15 minutes before serving.

Homemade Vanilla Sauce

While the cake bakes, you can prepare the simple vanilla sauce.

In a small saucepan, melt the ½ cup butter over medium heat.

Add the ¾ cup granulated sugar and ½ cup evaporated milk to the melted butter. Bring the mixture to a gentle boil, stirring occasionally.

Reduce the heat to low and boil gently for about 3-5 minutes, stirring continuously, until the sauce thickens slightly. It should coat the back of a spoon.

Remove the saucepan from the heat. Stir in the 1 teaspoon vanilla extract until fully incorporated.

Serve the vanilla sauce warm over slices of your freshly baked Tasty Rhubarb Cake.

Pro Tips for the Best Rhubarb Cake

Achieve a perfect bake every time with these helpful tips for your tasty rhubarb dessert.

• Don’t overmix the batter. Overmixing develops gluten, leading to a tough cake. Mix until just combined.
• Ensure rhubarb is chopped evenly. This promotes even baking and consistent texture in every bite.
• Prevent streusel from sinking. To help it stay on top, you can toss the streusel ingredients with 1 tablespoon of extra flour before sprinkling.
• Adjust baking time for pan size. A 9×13 pan bakes faster than a 9×9 pan. Keep an eye on it!
• Cover with foil if browning too quickly. If the top gets too dark before the center cooks, loosely tent foil over the pan.

Common Mistakes to Avoid

• Undermixing or overmixing the batter: Either extreme can affect the cake’s texture, making it crumbly or tough. Mix until just combined.
• Understanding why ingredient temperature matters is crucial for achieving a perfect cake crumb. Explore the science of room temperature ingredients in baking.
• Using cold ingredients: Room temperature eggs and buttermilk incorporate more smoothly, leading to a more consistent batter.
• Vanilla sauce curdling: Use a high-fat milk like evaporated milk or whole milk, and avoid boiling the sauce too vigorously or for too long. Gentle heat is key.

Serving Suggestions & Variations

Serve your Tasty Rhubarb Cake warm for the best experience. A generous drizzle of the homemade vanilla sauce is a must, but a scoop of vanilla ice cream or a dollop of whipped cream also works beautifully. Garnish slices with fresh mint leaves or a few extra berries like strawberries or raspberries for a pop of color and freshness.

For a brighter flavor, add a touch of lemon zest to the cake batter. If you love crunch, feel free to double the streusel topping for extra texture. You can also experiment with other fruit combinations; try adding chopped apples or blueberries alongside the rhubarb. This versatile dessert is delicious as a special breakfast cake, an afternoon snack, or an elegant after-dinner treat.

How to Store & Freeze Rhubarb Cake

Store your baked Tasty Rhubarb Cake tightly covered at room temperature for up to 2-3 days. For longer storage, refrigerate it for 3-4 days. Be aware that the streusel topping may soften when stored covered.

To freeze the cake, let it cool completely, then wrap individual slices or the entire cake tightly in plastic wrap, followed by aluminum foil. It will keep in the freezer for up to 3 months. Thaw frozen cake slices at room temperature or warm gently in the microwave or oven before serving. Store the vanilla sauce separately in an airtight container in the fridge for up to 3-4 days. Reheat the sauce gently over low heat, stirring frequently, until warm and smooth again.
