Ingredients

For the cake:
2 cups all-purpose flour
2 Tablespoons freshly grated lemon zest
1 teaspoon baking powder
1/2 teaspoon salt
1 1/2 cups sugar
1 cup melted butter
1 cup water
1/2 cup Greek yogurt
1 egg, lightly beaten
1 teaspoon vanilla extract
3/4 cup heavy whipping cream, cold

For the syrup:
1/2 cup water
6 Tablespoons caster sugar
3 Tablespoons lemon juice
1 Tablespoon rum

For the frosting:
8 ounces cream cheese, room temperature
4 ounces mascarpone cheese, room temperature
3/4 cup confectioners' sugar
2 teaspoons lemon juice

Directions

Preheat oven to 375 degrees Fahrenheit. In a large bowl, mix the flour, baking powder, sugar and salt. Add melted butter and beat with a hand mixer until smooth. Add the eggs, water, yogurt, and vanilla. Mix until well combined.

Spread the mixture into a greased 11x13" baking pan. Bake for 18-20 minutes or until a toothpick inserted near the center comes out clean.

Meanwhile, make the lemon syrup, by boiling the water and the sugar together, then add the lemon juice. Boil for about 3 minutes. Remove from the heat. Let cool and mix with rum. Remove the cake from the oven and drizzle with the syrup. Leave to cool.

In a medium bowl, beat the cream cheese, mascarpone, lemon juice and confectioners' sugar until smooth. Stir in the whipped cream. Spread the frosting over the cake. Store in the refrigerator.
