How to Make Rhubarb Cake with Butter Sauce

Step 1: Prepare the Rhubarb

Start by washing and trimming the rhubarb stalks, then cut them into even, bite-sized pieces. This ensures they cook evenly and distribute flavor throughout the cake.

Step 2: Mix the Dry Ingredients

In a medium bowl, combine all-purpose flour, baking powder, and a pinch of salt. Sifting these together helps create a light, airy cake texture.

Step 3: Cream Butter and Sugar

In a large bowl, beat softened butter and sugar until fluffy and pale, which creates the perfect base for your batter.

Step 4: Add Eggs and Vanilla

Incorporate the eggs one at a time, beating well after each addition, then stir in vanilla extract to enhance the flavor profile.

Step 5: Combine Wet and Dry Ingredients

Alternate adding the dry ingredients and milk to the creamed mixture, stirring gently to avoid overmixing, keeping the batter tender.

Step 6: Fold in Rhubarb

Gently fold the rhubarb pieces into the batter, distributing them evenly without breaking them down too much.

Step 7: Bake the Cake

Pour the batter into a greased baking pan and bake in a preheated oven at 350°F (175°C) for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean.

Step 8: Prepare the Butter Sauce

While the cake bakes, melt butter in a saucepan, then whisk in brown sugar and a splash of cream or milk until smooth and slightly thickened. This sauce is the crowning glory of the dessert.

Step 9: Serve with Warm Butter Sauce

Once the cake has cooled slightly, serve individual slices drizzled generously with the warm butter sauce for that rich finishing touch.

Pro Tips for Making Rhubarb Cake with Butter Sauce

• Use Fresh Rhubarb: Fresh rhubarb gives the best vibrant tartness and texture compared to frozen.
• Cut Rhubarb Uniformly: Ensures even baking and prevents chunks from sinking to the bottom.
• Don’t Overmix Batter: Mix until just combined to keep the cake light and fluffy.
• Butter at Room Temperature: Creaming room-temperature butter traps air, making your cake tender.
• Warm Butter Sauce Before Serving: Warm sauce is silky and perfectly coats each slice, enhancing every bite.
