Instructions

Rhubarb loaf cake:

  1. Preheat the oven to 180 degrees Celsius/ 350°F/ 180°C. Butter the loaf pans.
  2. Prepare rhubarb: Wash the rhubarb; you don't have to peel it. Discard the leaves as they are poisonous. If the rhubarb stalk is very thick, cut it lengthwise before thinly slicing it crosswise. If the blackberries are very large, halve them. Set both aside.1 cup rhubarb/ 100 g + 1⅔ cup blackberries/ 170 g
  3. Mix ingredients: Place the brown sugar, the oil, and the egg in a large bowl and beat until blended. Add the buttermilk, yogurt, and vanilla extract and blend again.1½ cups brown sugar/ 270 g + ¼ cup vegetable oil/ 60 ml + 1 egg + ½ cup buttermilk/ 120 ml + ⅔ cup creamy yogurt/ 170 g + 1 teaspoon pure vanilla extract
  4. Add dry ingredients: In another bowl, the flour, baking soda, and salt. Gradually add the flour mixture to the wet mixture.2½ cups all-purpose flour/ 300 g + 1 teaspoon baking soda + ¼ teaspoon fine sea salt
  5. Divide the mixture between the two loaf pans.

Topping:

  1. Melt the butter in a small pan. Stir the cinnamon and granulated sugar into the melted butter to form sugar lumps. Dollop the lumps evenly over the batter in the pans.2 tablespoons unsalted butter + 2 teaspoons cinnamon + ½ cup granulated sugar
  2. Bake for 50 minutes or until a toothpick inserted in the middle of the loaf cake comes out with only a few crumbs hanging to it.
  3. Cool in the pan for about 10 minutes, remove and let cool completely on a wire rack.

Notes

  • Measurements: A digital kitchen scale (the Amazon affiliate link opens in a new tab) will give you the most precise measures.
  • Neutral-tasting vegetable oil is perfect for making extra moist cakes that keep moist for several days. I usually use canola oil.
