Step-by-Step Directions for Rhubarb Cake with Butter Sauce
Preheat the oven
Begin by preheating your oven to 175°C (350°F). Greasing a 9×13-inch baking dish with butter ensures that your cake will release easily once baked.
Cream butter and sugar
In a mixing bowl, take your softened unsalted butter and granulated sugar. Using an electric mixer, beat them together until the mixture is light and fluffy, which should take about 3-5 minutes. This step is crucial as it incorporates air into the batter, improving the texture of your cake.
Add vanilla
Now, add the 2 teaspoons of vanilla extract to the creamed butter and sugar mixture and mix well until fully incorporated. The addition of vanilla elevates the cake, adding a sweet aroma with each bite.
Mix dry ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures that the leavening agent is evenly distributed throughout the batter, preventing any bubbly lumps that might occur later.
Combine wet and dry
Gradually alternate adding the flour mixture and buttermilk to the creamed butter and sugar. Mix just until combined, being careful not to overmix; this will keep your cake tender.
Fold in rhubarb
Using a spatula, gently fold in the diced fresh rhubarb. The pieces will soften during baking, adding tart bursts of flavor in each slice of cake.
Bake the cake
Pour the batter into the greased baking pan and spread it evenly. Bake in your preheated oven for 40-45 minutes until the cake turns a golden brown and a toothpick inserted into the center comes out clean.
Make the butter sauce
While the cake bakes, it’s time to prepare the buttery sauce. In a saucepan over medium heat, combine the 1/2 cup unsalted butter, heavy cream, and 1 cup of granulated sugar. Allow the mixture to come to a gentle simmer while stirring constantly until the sugar dissolves. Remove from heat and stir in the 1 teaspoon of vanilla extract.
Serve
Once the cake has finished baking and cooled slightly, slice it into generous portions. Pour the warm butter sauce over the slices just before serving, allowing it to drizzle down the sides, melding beautifully with the cake.
Tips & Tricks for Rhubarb Cake with Butter Sauce
To achieve the perfect Rhubarb Cake with Butter Sauce, consider these handy tips. Make sure the rhubarb is fresh and firm, as this will enhance the flavor and texture of your cake. You can also use frozen rhubarb, but make sure to thaw and drain any excess moisture before adding it to the batter.
If you want a richer flavor in your butter sauce, consider adding a pinch of cinnamon or a touch of almond extract. For those who enjoy nutty flavors, adding chopped walnuts or pecans to the cake batter before baking can provide a delightful crunch that complements the cake’s soft crumb.
