Preheat your oven to 350°F.

Prepare a 9x13-inch baking dish by greasing it lightly with butter or non-stick spray.

Mix the cake batter in a large bowl, combining dry ingredients first, then adding wet ones until just combined.

Fold in fresh strawberries gently, being careful not to overmix.

Pour the batter into the prepared baking dish, spreading it out evenly.

Create the cream cheese mixture by beating together softened cream cheese and powdered sugar until smooth.

Dollop spoonfuls of the cream cheese mixture over the top of the cake batter and swirl it in with a knife.

Bake in your preheated oven for 45-50 minutes or until a toothpick inserted comes out clean from the edges but slightly moist from the center.
