Line a baking sheet or 9x13 inch pan with parchment paper, ensuring it covers the bottom and slightly overhangs the sides for easy removal later. Finely chop the semi-sweet chocolate into small, uniform pieces to ensure even melting. Finely chop 1/2 cup of the freeze-dried strawberries and slice the remaining 2/3 cup thin. Have all ingredients measured and ready before you begin melting—this is critical since chocolate can go from perfectly melted to overcooked quickly.

Heat the chopped semi-sweet chocolate in the microwave in 30-second intervals, stirring thoroughly between each interval until completely smooth and melted—this takes about 1-2 minutes total depending on your microwave. Once melted, stir in the vanilla extract and sea salt, which will enhance the chocolate's flavor and add complexity. I find that a pinch of salt makes the chocolate taste richer without tasting salty, so don't skip it.

Fold the finely chopped strawberries and crispy rice cereal into the melted chocolate base until everything is evenly coated and distributed. The cereal adds a satisfying crunch that contrasts beautifully with the creamy chocolate, and the chopped strawberries incorporate a fruity tartness throughout. Work quickly but gently so you don't crush the cereal too much.

Pour the chocolate-cereal mixture onto the prepared parchment-lined pan and spread it into an even layer about 1/4 inch thick, working quickly before it sets. Immediately scatter the sliced freeze-dried strawberries and white chocolate chips across the surface, pressing them gently but firmly into the chocolate so they stick. I like to press the toppings down right after spreading because the chocolate is still warm enough for them to adhere properly.

Place the bark in the refrigerator for 15-20 minutes until the chocolate is completely set and firm to the touch. Once chilled, break the bark into irregular, bite-sized pieces by hand or using a knife. Store in an airtight container at room temperature for up to two weeks, or in the refrigerator if your kitchen is warm.
