Method
- Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking dish thoroughly with butter or nonstick spray, and line with parchment if desired for easy removal.
- In a large mixing bowl, combine the cake mix, 4 large eggs, and 3/4 cup vegetable oil. Use a hand mixer or stand mixer on low to medium speed and mix until smooth, about 1 to 2 minutes. Scrape down the sides once to ensure even mixing.
- Stir in 1 cup sour cream until fully incorporated. Fold in 1 cup chopped strawberries gently so they stay distributed and don’t bleed too much color into the batter.
- Pour half of the batter into the prepared 9×13 baking dish, spreading it evenly with a spatula. If you like more visible strawberry ribbons, you can reserve a few extra chopped strawberries to press into the top.
- In a small bowl, mix the remaining batter with additional strawberries if desired (a few tablespoons of chopped berries). Dollop or spoon this mixture over the first layer and gently swirl with a knife to create a marbled effect.
- Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean or with only a few moist crumbs. If the top is browning too quickly, tent loosely with foil for the last 10 minutes of baking.
- Remove from the oven and let the cake cool in the pan on a wire rack for at least 20 minutes. Meanwhile, prepare the icing by whisking together 1/2 cup powdered sugar, 2 tablespoons milk, and 1 teaspoon vanilla extract until smooth. Add an extra teaspoon of milk if you want a thinner drizzle.
- Once the cake is cooled but still slightly warm, drizzle the strawberry cream icing over the top evenly. Allow the icing to set for a few minutes before slicing into squares and serving.
Notes
Store leftovers covered in the refrigerator for up to 4 days. The icing is best within the first couple of days.
