01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan and line with parchment paper for easy removal.
02 - Combine vanilla cake mix, eggs, vegetable oil, and whole milk in a large bowl. Beat until smooth, then pour into prepared pan.
03 - Beat softened cream cheese and butter until fluffy. Add powdered sugar and vanilla extract, mixing until smooth and creamy.
04 - Drop spoonfuls of cheesecake mixture evenly over cake batter. Gently swirl with a knife or spatula to create marbled effect.
05 - Distribute strawberry pie filling and sliced fresh strawberries over surface. Swirl gently again to incorporate strawberry ribbons.
06 - Sprinkle white chocolate chips and sliced almonds evenly across the top of the cake.
07 - Bake for 45-50 minutes until edges are golden brown and center is mostly set. Slight wobble in center is acceptable.
08 - Allow cake to cool in pan for at least 20 minutes before slicing and serving.
