Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9×9-inch square baking pan or line it with parchment paper for easy removal.
Step 2: Prepare the Rhubarb
If using fresh rhubarb, chop it into small pieces. If using frozen rhubarb, there’s no need to thaw it; just chop it while still frozen.
Step 3: Combine Dry Ingredients
In a medium bowl, whisk together the flour, 3/4 cup of granulated sugar, baking soda, and salt. Set aside. This mixture adds the right texture to your cake.
Step 4: Cream the Butter and Sugar
In a large mixing bowl, beat together the softened butter and remaining 1/4 cup of sugar until light and fluffy. This process typically takes about 2-3 minutes and incorporates air into the mixture, helping your cake rise beautifully.
Step 5: Add Eggs and Wet Ingredients
Add the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract and buttermilk until combined.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet mixture. Stir until just combined; be careful not to overmix. Fold in the chopped rhubarb gently, so it’s evenly distributed throughout the batter.
Step 7: Bake the Cake
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The cake will be lightly browned on top and spring back when touched.
Step 8: Cool and Serve
Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Once cooled, dust with powdered sugar before serving if desired. This cake can be enjoyed warm or at room temperature!
