Ingredients:

  • 250g all-purpose flour
  • 300g granulated sugar
  • 10g baking powder
  • 3g salt
  • 3 large eggs
  • 240g full-fat sour cream
  • 120ml neutral oil
  • 15g fresh lemon zest
  • 5ml vanilla extract
  • 60ml fresh lemon juice
  • 180g powdered sugar
  • 360ml cold heavy whipping cream
  • 115g full-fat cream cheese
  • 2ml lemon extract

Instructions:

  1. Preheat the oven to 175°C (350°F). Grease your 9 inch pan thoroughly with oil or butter. Note: This ensures the edges don't stick when you try to slice it later.
  2. Whisk the 3 eggs, 300g sugar, 120ml oil, 240g sour cream, 15g lemon zest, and 5ml vanilla in a large bowl. Whisk until the mixture is a pale, uniform yellow and completely smooth.
  3. Sift the 250g flour, 10g baking powder, and 3g salt directly into the wet ingredients. Note: Sifting aerates the flour, contributing to that lightweight cooler texture.
  4. Fold the dry ingredients into the wet using a spatula. Stop the moment you see no more white streaks of flour. Do not over mix, or the cake will be tough.
  5. Pour the batter into the prepared pan. Bake for 30 minutes until the center springs back and the edges are a light golden brown.
  6. Whisk the 60ml lemon juice and 60g powdered sugar in a small bowl while the cake is in its final minutes of baking. This creates our Cooler soak.
  7. Poke holes all over the surface of the cake using a skewer while it is still hot. Pour the lemon soak slowly over the top, letting it vanish into the sponge.
  8. Beat the 115g softened cream cheese, 120g powdered sugar, and 2ml lemon extract in a separate bowl until it looks like a thick, smooth paste.
  9. Whip the 360ml heavy cream in another cold bowl until it reaches stiff peaks that hold their shape.
  10. Fold the whipped cream into the cream cheese mixture gently. Spread the frosting over the completely cooled cake and chill for at least 2 hours. The resting period is where the technology of the soak really pays off. As the cake chills, the lemon syrup redistributes through the crumb, and the cream cheese in the frosting sets into a stable, sliceable layer. If you cut into it too early, you'll miss that specific cooler sensation where the cake feels almost like a chilled citrus truffle. | Step | Time Check | Sensory Cue | | :--- | :--- | :--- | | The Emulsion | 3 mins | Batter should look like thick, glossy ribbons. | | The Bake | 30 mins | The aroma of cooked lemon should fill the room. | | The Soak | 2 mins | The syrup should sizzle slightly as it hits the warm cake. | If you're looking for another project that uses cream cheese for structural stability, you might enjoy my [mini salted caramel cheesecakes](https://hellorecipes.net/recipes/mini-salted-caramel-cheesecakes/), which use a similar technology to achieve a velvety bite.
