Preheat oven to 350F and spray an 8x8 baking dish with nonstick cooking spray.
Set cream cheese out to warm to room temp.
Mix the dry ingredients together in a large bowl.
Gradually add the Greek yogurt and eggs to the dry ingredients. Stir until everything is evenly mixed. The batter should be fairly thick but spreadable.
Transfer the cake bars batter to the baking dish and spread it evenly to cover the entire dish. (A rubber spatula or spatula sprayed with cooking spray helps prevent any sticking.)
Bake the bars for 14-16 minutes or until the center of the cake bars can pass the toothpick test.
While the bars are in the oven, wash, de-stem, and cut the strawberries into 4 pieces each. Set aside.
Add the chocolate chips and cream cheese to a microwave-safe bowl. Microwave for 45-60 seconds or until melted, stirring often. Stir until everything is evenly incorporated.
Once the cake bars are baked, remove to cool.
Add the strawberries on top of the cake bars and pour the white chocolate and cream cheese mixture on top. Place the cake bars in the refrigerator for at least 30 minutes to allow the chocolate to set.
Slice the cake bars into 16 pieces. Store in the refrigerator.
