Grease a 9"-x-13" baking pan with butter. In a large pot over medium heat, melt butter. Add marshmallows and stir until completely melted. Remove from heat and stir in Rice Krispies.
Fold in 2 cups white chocolate chips and 2 cups strawberries. Pour into pan and smooth top, being careful not to pack Rice Krispies into the pan too much.
In a microwave-safe bowl, melt remaining ½ cup white chocolate chips in 30-second intervals until smooth. Drizzle over Rice Krispies, then top with remaining ½ cup of strawberries.
Let sit until cool and chocolate has hardened, 30 minutes.
