A 7" cake. It puffs and settles. |
3 T [try doubling this for a denser cake] all-purpose flour (can be whole wheat)
1 ⅔ cups whole-milk Greek yogurt, or strain regular yogurt in a coffee filter for an hour or two.
1 lemon, zested and juiced
Pinch of salt (optional), cinnamon to taste
- Using an electric hand mixer, beat egg whites until they're stiff peaks
- Using the same mixer, combine yolks and sugar (no need to wash beaters after the egg white). Beat on medium-high until the mixture is very pale and fluffy, about 3 minutes.
- Mix in flour, yogurt, lemon zest and juice, and salt until fully incorporated.
- Gently fold half of the egg whites into the yolk-yogurt mixture until only a few streaks remain.
- Fold in the remaining whites, scraping the bottom and sides of the bowl, until the batter is evenly mixed, light and smooth.
- If you add blueberries, add a little flower to coat them. Take about 2/3 of the blueberries and mix in the batter. Save the rest for the top.
- Scrape the batter into prepared pan(s) and smooth into an even layer. Set the balance of the berries on top of the cake/s. These will not sink.
- Bake until the top is speckled with golden brown and puffed, 35 to 55 minutes. ( This burns if you don't watch it! You can cover with tin foil if it's browning too fast.
- Transfer the pan to a wire rack and let cake cool before cutting. Serve warm or cold.
