Ingredients
Method
- Preheat oven to 350°F (175°C). Mix cake mix, 3 eggs, 1/3 cup oil, 1 cup water, and 1 tbsp lemon zest for 2 minutes. Divide between 2 greased 9-inch pans and bake 26 to 30 minutes. Cool completely.
- Whip 1 cup heavy cream to firm peaks and refrigerate. Beat 8 oz cream cheese with 1 1/2 cups powdered sugar, 1 tsp vanilla, 2 tbsp lemon juice, and 1 tbsp lemon zest until smooth. Fold in the whipped cream.
- Stir remaining 1 tbsp lemon juice with 1 tbsp milk and 1 tsp powdered sugar to make the lemon soak.
- Brush soak over the first cake layer, spread 2 tbsp lemon curd on top, then spread half the cream cheese filling over it. Add the second layer soaked side down, spread remaining filling over the cake, and refrigerate 30 minutes.
- Whip remaining 1 cup heavy cream with 2 tbsp granulated sugar to stiff peaks. Frost the chilled cake, scatter lemon zest over the top, slice, and serve.
Notes
The active prep takes about 30 minutes, but build in at least 1 hour for the cake layers to cool and 30 minutes for the assembled cake to chill before frosting. You can split the work over 2 days: bake the layers the night before, wrap them, and fill and frost the next day. The lemon flavor gets a little more pronounced after a few hours in the fridge, so a make-ahead approach actually works in your favor here.
