Ingredients

- 2 cups all-purpose flour
- 1 cup granulated sugar

- 1 cup milk
- 2 cups fresh rhubarb, chopped into small pieces
- 2 large eggs
- 2 tsp baking powder

Ingredient Notes and Substitutions
- Rhubarb: Fresh rhubarb is best, but frozen rhubarb can also be used. If using frozen, thaw it completely and drain excess liquid before adding it to the batter.
- Butter: Unsalted butter gives the best flavor, but you can also use neutral oil for a softer crumb texture.
- Milk: Whole milk gives a richer cake, but low-fat or plant-based milk also works well.
- Sugar: You can slightly reduce sugar if you prefer a less sweet dessert, but keep enough for proper texture.
- Vanilla extract: Adds warmth and enhances the flavor of the cake.
Step-by-Step Instructions
Step 1: Prepare the oven and baking pan
Preheat your oven to 350°F (175°C). This ensures the cake bakes evenly from the moment it goes in.
Grease a medium-sized baking pan thoroughly with butter or oil. You can also lightly dust it with flour to prevent sticking. Make sure to coat corners and edges well so the cake releases easily after baking.
Step 2: Prepare dry ingredients

In a medium mixing bowl, add all-purpose flour, baking powder, and salt.
Whisk everything together slowly and evenly so the baking powder is fully distributed. This step helps the cake rise properly and keeps the texture light and fluffy.
Step 3: Cream butter and sugar
In a large mixing bowl, add softened butter and sugar.
Beat them together until the mixture becomes light, creamy, and slightly fluffy. This may take a few minutes by hand or with a mixer. Proper creaming helps create a soft cake texture and gives structure to the batter.
Step 4: Add eggs and vanilla
Add the eggs one at a time into the butter and sugar mixture. Mix well after each addition so the batter stays smooth and does not separate.
Once the eggs are fully combined, add vanilla extract and mix again until the batter looks creamy and even.
Step 5: Combine wet and dry ingredients
Slowly add the dry flour mixture into the wet mixture in small portions.
Alternate with milk, adding a little at a time while mixing gently. Stir just until everything is combined. Do not overmix, as this can make the cake dense instead of soft.
The batter should look thick, smooth, and slightly creamy.
Step 6: Fold in rhubarb

Add chopped rhubarb into the batter.
Gently fold it in using a spatula or spoon so the pieces are evenly spread throughout. The rhubarb should be coated in batter but still visible. This ensures every slice has a balance of sweet cake and tangy fruit.
Step 7: Transfer to baking pan and bake

Pour the batter into the prepared baking pan. Spread it evenly using a spatula, but do not worry about making it perfect.
Place the pan in the preheated oven and bake for about 35 to 45 minutes.
The cake is done when the top is golden and a toothpick inserted in the center comes out clean or with only a few moist crumbs.
Step 8: Cool and serve
Remove the cake from the oven and let it cool in the pan for at least 15 to 20 minutes.
After cooling slightly, transfer it to a rack or serve directly from the pan. The cake tastes best when slightly warm or fully cooled, allowing the flavors to settle.

Notes
- Fresh rhubarb gives the best texture and flavor, but frozen rhubarb can be used. Thaw completely and drain excess liquid before adding it to the batter.
- Cut rhubarb into evenly sized pieces so it bakes evenly throughout the cake.
- Do not overmix the batter after adding the flour. Overmixing can create a dense cake instead of a soft, tender crumb.
- Use room-temperature butter, eggs, and milk for a smoother batter and more even baking.
- Oven temperatures can vary. Begin checking for doneness around 35 minutes by inserting a toothpick into the center of the cake.
- If the top begins browning too quickly, loosely cover the cake with foil during the final part of baking.
- Allow the cake to cool for at least 15 to 20 minutes before slicing. This helps the crumb set properly and prevents the cake from falling apart.
- For extra sweetness, lightly dust the cooled cake with powdered sugar before serving.
- A dollop of whipped cream or a scoop of vanilla ice cream pairs beautifully with the tart rhubarb flavor.
