Step-by-Step: How to Make Classic Rhubarb Cake

Prepping Your Rhubarb
Trim off the leaves (they’re toxic), wash the stalks, and chop into ½-inch pieces. If the stalks are very thick, peel away any stringy bits.
Mixing the Batter
Cream butter and sugar together, beat in the eggs, then alternate adding your dry ingredients and milk. Fold in the rhubarb last.

Use a 9×13 pan and bake at 350°F for 45–50 minutes. You’ll know it’s ready when a toothpick comes out clean and the top is golden.
