How to Make It

Follow these steps for a delightful baking experience.

Cream

In a bowl, cream together the softened butter and sugar until light and fluffy.

Add

Add eggs and vanilla extract, then mix well until fully incorporated.

Whisk

In another bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with milk until well combined.

Fold

Fold in the chopped rhubarb gently to avoid breaking it down too much.

Pour

Pour the batter into the prepared cake pan and bake for about 30-35 minutes, or until a toothpick comes out clean.

Melt

For the butter sauce, melt butter in a pan over medium heat, then whisk in powdered sugar, milk, and vanilla until smooth.

Drizzle

Serve the cake warm, drizzled generously with the butter sauce.

How to Store It

Fridge: Store for up to 4 days in an airtight container.
Freezer: No, because it may alter the cake’s texture.
Reheat: Microwave for 20-30 seconds until warm.

Tips for Best Results

• Ensure your butter is softened to room temperature for easy creaming.
• Don’t overmix the batter once you add the dry ingredients; this keeps the cake tender.
• Use a toothpick to check for doneness; it should come out clean from the center.
• Serve the cake warm for an irresistible experience.

Serving Suggestions

• Pair with a scoop of vanilla ice cream for a creamy contrast.
• Enjoy with a cup of tea or coffee for afternoon indulgence.
• Top with fresh whipped cream and additional rhubarb for extra flair.
