How to Assemble
Step 1:
Preheat your oven to 350 degrees. Butter your nine-inch round cake pan. Line the bottom with a piece of parchment paper.
Step 2:
Trim your rhubarb stalks into even pieces. Lay them across the bottom of the pan. Make sure they cover the surface in one layer.
Step 3:
Sprinkle a little sugar over the raw rhubarb. This helps the fruit caramelize while it bakes. Set the pan aside for a few minutes.
Step 4:
Whisk your flour, baking powder, and salt together. Ensure there are no lumps in the dry mixture. This creates a very smooth cake batter.
Step 5:
Cream the butter and sugar in your mixer. Beat them until the mixture looks pale and fluffy. This step adds air to the cake.
Step 6:
Add the eggs one at a time. Mix well after you add each egg. Pour in the vanilla extract and mix again.
Step 7:
Fold in the dry ingredients and sour cream. Alternate between the two for a smooth texture. Do not overmix the batter at this stage.
Step 8:
Spread the batter over the rhubarb in the pan. Use a spatula to smooth out the top. Ensure the fruit is completely covered by batter.
Step 9:
Bake the cake for about forty-five minutes. A toothpick should come out clean from the center. The top will look golden and firm.
Step 10:
Cool the cake in the pan for ten minutes. Run a knife around the edges to loosen it. Invert it carefully onto a serving plate.
Recipe Success Tips
- Use fresh, bright pink rhubarb stalks for the best color.
- Make sure your butter is soft before you start mixing.
- Do not overwork the batter or the cake becomes tough.
- Line the pan with parchment to avoid a sticky mess.
- Let the cake rest before flipping it onto a plate.
- Cut the rhubarb into uniform sizes for even cooking.
- Wipe the stalks dry before placing them in the pan.
How To Store Leftover
You can keep this cake at room temperature. Cover it tightly with plastic wrap or a dome. It stays fresh for about two days this way.
If you want it to last longer, use the fridge. It will stay good for up to five days. Simply warm a slice before you eat it. The fruit tastes best when it is slightly warm.
Sides & Pairings Suggestions
This cake tastes amazing with a scoop of ice cream. Vanilla bean is the most popular choice for many. The cold cream melts into the warm tart fruit.
You can also serve it with a dollop of whipped cream. A little bit of Greek yogurt works well too. Some people enjoy it with a hot cup of tea. It makes a perfect afternoon snack for guests.
