Prepare the Pan
Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.
Chocolate Layer
Melt semi-sweet chocolate, butter, and 2 tablespoons of condensed milk over low heat.
Stir constantly to prevent burning.
Pour into prepared pan, smooth with a spatula, and chill 10–15 minutes until set.
Strawberry Layer
Melt white chocolate with remaining condensed milk and vanilla over low heat.
Stir in strawberry powder or puree until fully combined.
Pour gently over the set chocolate layer, smooth evenly, and chill again until firm.
Optional Topping
Sprinkle extra freeze-dried strawberry pieces or mini chocolate chips while still slightly warm.
Slice & Serve
Lift fudge from pan using parchment overhang.
Slice with a sharp knife, wiping clean between cuts for neat edges.
