Ingredients
  

For the Cake:

  • 2 cups all-purpose flour
  • 1 ½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup sugar
  • ½ cups unsalted butter, softened
  • 2 large eggs
  • 1 cups buttermilk (or 1 cup milk + 1 tbsp vinegar)
  • 1 tsp vanilla extract
  • 2 cups diced rhubarb

For the Topping (Optional):

  • ¼ cup sugar
  • ½ tsp cinnamon

Instructions
 

Step 1: Prepare the Cake Batter

  • Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking dish.
  • In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  • In a large mixing bowl, cream butter and sugar until light and fluffy.
  • Add eggs one at a time, beating well after each addition. Stir in vanilla extract.

Step 2: Add the Rhubarb

  • Gradually mix in the flour mixture and buttermilk, alternating between the two.
  • Gently fold in the diced rhubarb, making sure it’s evenly distributed.

Step 3: Bake the Cake

  • Pour the batter into the prepared baking dish and spread it evenly.
  • Mix ¼ cup sugar and cinnamon, then sprinkle over the top of the cake.
  • Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
  • Let cool for at least 15 minutes before serving.

Notes

  • Fresh or frozen rhubarb? If using frozen, thaw and drain excess liquid before adding to the batter.
  • If you prefer a sweeter cake, increase sugar slightly or serve with whipped cream.
  • Store leftovers in an airtight container at room temperature for up to 3 days or in the fridge for 5 days
