Ingredients
Scale
- 340 g all-purpose flour
- 2 tbsp cornstarch
- 3/4 tsp baking powder
- 3/4 tsp baking soda
- 3/4 tsp salt
- 300 g granulated sugar
- Zest of one large organic lemon or two small
- 180 g butter (room temperature)
- 4 large eggs (room temperature)
- 240 g sour cream (room temperature)
- 60 g vegetable oil (e.g. canola oil)
- 2 tbsp lemon juice
- 2 tsp vanilla extract
- 400 g butter (for frosting)
- 660 g powdered sugar
- 2 tbsp freeze-dried strawberry powder
- 2 tsp vanilla extract
- 2–3 tbsp whole milk (room temperature)
- Fresh strawberries
- Lemon slices
Instructions
- Preheat the oven to 350°F (175°C) and grease two 9-inch round cake pans.
- In a large mixing bowl, combine all-purpose flour, cornstarch, baking powder, baking soda, and salt. Whisk together until well blended.
- In a stand mixer bowl, beat together butter, granulated sugar, and lemon zest until light and fluffy, about 3–5 minutes.
- Add in eggs one at a time, mixing well after each addition, followed by sour cream, vegetable oil, lemon juice, and vanilla extract. Mix until fully combined.
- Gradually add the dry ingredients into the wet mixture while mixing on low speed until just combined.
- Divide the batter evenly between the prepared pans. Bake in preheated oven for about 22 minutes or until a toothpick inserted into the center comes out clean.
- Allow cakes to cool in pans for 10 minutes before transferring them to a wire rack to cool completely.
- For frosting, beat room temperature butter until creamy. Gradually add powdered sugar while mixing on low speed, then mix in freeze-dried strawberry powder and vanilla extract. Adjust consistency with whole milk as needed until smooth and spreadable.
- Once cooled, place one layer of cake on a serving platter and spread an even layer of strawberry buttercream on top. Place the second layer on top and frost the entire cake with the remaining buttercream.
- Decorate with fresh strawberries and lemon slices as desired before slicing and serving.
