Ingredients
For the Cake:
- 2 ¼ cups cake flour (or all-purpose flour, sifted)
- 1 ½ cups granulated sugar, divided
- 1 tbsp baking powder
- ½ tsp salt
- 7 large egg whites
- 5 large egg yolks
- ½ cup vegetable oil
- ¾ cup water
- 1 tbsp lemon zest
- 1 tbsp fresh lemon juice
- 1 tsp vanilla extract
- ¼ tsp cream of tartar
For the Lemon Glaze:
- 1 cup powdered sugar
- 2 tbsp fresh lemon juice
- 1 tsp lemon zest
For the Crunch Topping:
- 1 ½ cups crushed vanilla wafers or shortbread cookies
- ½ cup all-purpose flour
- ½ cup granulated sugar
- ½ tsp salt
- ½ cup unsalted butter, melted
Step-by-Step Instructions
1. Make the Cake Batter
- Preheat oven to 325°F (163°C).
- In a large bowl, sift together cake flour, ¾ cup sugar, baking powder, and salt.
- In another bowl, whisk egg yolks, oil, water, lemon zest, lemon juice, and vanilla.
- Combine wet and dry ingredients until smooth.
- In a separate bowl, beat egg whites and cream of tartar until soft peaks form. Gradually add remaining ¾ cup sugar and beat until stiff peaks.
- Gently fold egg whites into the batter in thirds (keep it airy!).
2. Bake the Cake
- Pour batter into an ungreased tube pan (key for height—don’t use Bundt!).
- Bake 55–65 minutes until a toothpick comes out clean.
- Invert pan and cool completely upside-down (prevents sinking).
3. Make the Crunch Topping
- Mix crushed cookies, flour, sugar, salt, and melted butter until crumbly.
- Bake on a sheet at 350°F (177°C) for 10–12 minutes, stirring halfway. Cool completely.
4. Glaze & Assemble
- Whisk powdered sugar, lemon juice, and zest for the glaze.
- Drizzle over cooled cake, then press crunch topping onto the glaze while tacky.
- Chill 20–30 minutes before slicing for clean cuts.
Pro Tips for Success
Use room-temperature eggs for better volume in the meringue.
Don’t overmix after adding egg whites—keep it fluffy!
No tube pan? A 9×13″ pan works (adjust baking time to ~35 mins).
Storage: Keep covered at room temp for 2 days or refrigerate for up to 5 days.
