Lemon snack cake

Level 10 of 100Foundation50 min350°F / 175°CSoda versus powder

Formula

  • 180 g flour
  • 150 g sugar
  • 6 g baking powder
  • 2 g soda
  • 3 g salt
  • 180 g yogurt
  • 2 eggs
  • 100 g oil
  • zest of 1 lemon

Method

  1. Start. Whisk dry ingredients. Whisk yogurt, eggs, oil, and zest separately.Watch for: Scrape the bottom and sides once, then stop at the texture described; extra mixing can add air or develop unwanted gluten.
  2. Then. Fold together and spread in an 8-inch lined pan.Watch for: Cut through the center and sweep up the side while rotating the bowl; stop when the last dry streak disappears so you preserve air and tenderness.
  3. Finish. Bake 28–34 minutes; cool, then dust or glaze.Watch for: Begin checking at the early end of the range; use the stated color, movement, or internal-temperature cue rather than time alone. Apply a thin, even coat and keep it off cut edges or seams unless the step says otherwise.

The concept

Chemical leaveners release carbon dioxide, but their timing and acid requirements differ.
