Description

A cozy loaf cake featuring tart rhubarb and bright lemon flavors, finished with a glossy glaze.


Ingredients

  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp fine salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs, at room temperature
  • 1 tsp vanilla extract
  • 1/4 cup plain yogurt or buttermilk
  • 1/4 cup milk
  • Zest of 2 lemons
  • 1/3 cup fresh lemon juice (about 2 lemons)
  • 1 1/2 cups rhubarb, chopped into 1/2-inch pieces
  • 1 tbsp cornstarch (tossed with rhubarb)
  • For the glaze: 1 cup powdered sugar and 2-3 tbsp lemon juice


Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line with parchment for easy removal.
  2. Toss chopped rhubarb with cornstarch in a small bowl so the pieces won’t sink and will release less liquid.
  3. Whisk together flour, baking powder, baking soda, and salt in a medium bowl.
  4. Beat the butter and sugar until pale and fluffy (about 2–3 minutes). Add eggs one at a time, mixing well after each. Stir in vanilla and lemon zest.
  5. Mix in half the dry ingredients, then the yogurt and milk, then the remaining dry ingredients. Stir just until combined.
  6. Fold the rhubarb into the batter so it’s evenly distributed.
  7. Pour batter into the prepared loaf pan. Bake for 50–60 minutes, or until a toothpick comes out with a few moist crumbs. Tent with foil if the top browns too quickly.
  8. While the loaf cools in the pan for 10 minutes, mix lemon juice with 2 tbsp sugar and prick the top with a skewer. Spoon the lemon soak over the loaf so it absorbs into the crumb.
  9. When cool, whisk powdered sugar and remaining lemon juice until pourable and drizzle over the loaf.

Notes

Use fresh, firm rhubarb for best results. Room-temperature ingredients improve texture.
