1. Preheat the Oven

• Preheat your oven to 350°F (175°C).
• Grease and flour a 9×13-inch baking pan.

2. Prepare the Cake Batter

• In a large mixing bowl, combine the red velvet cake mix, vegetable oil, sour cream, eggs, strawberry puree, and vanilla extract.
• Mix until the batter is smooth and well combined.

3. Prepare the Cinnamon Swirl

• In a separate bowl, mix together the brown sugar and ground cinnamon.

4. Assemble the Cake

• Pour half of the cake batter into the prepared baking pan.
• Sprinkle half of the cinnamon-sugar mixture evenly over the batter.
• Pour the remaining batter on top and sprinkle the rest of the cinnamon-sugar mixture.
• Use a knife to gently swirl the batter, creating a marbled effect.

5. Bake the Cake

• Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
• Allow the cake to cool completely in the pan.

6. Prepare the Strawberry Cream Cheese Icing

• In a mixing bowl, beat the softened cream cheese and butter until smooth and creamy.
• Gradually add the powdered sugar, mixing until fully incorporated.
• Stir in the strawberry puree and vanilla extract until the icing is smooth and spreadable.

7. Frost the Cake

• Once the cake has cooled, spread the strawberry cream cheese icing evenly over the top.
• Optionally, garnish with fresh strawberry slices or a drizzle of strawberry syrup
