Prep Your Station. Before starting, make sure you have everything ready to go, since things will move quickly. Line an 8x8 or 9x9 metal pan with parchment paper or lightly grease. Add crisp rice cereal to a large bowl with plenty of room to mix.

Grind Strawberries. Add 1 cup freeze-dried strawberries to a food processor or blender and pulse or puree until you have a fine powder.

Set Aside Some Marshmallows. Place 1 cup of marshmallows off to the side (we'll add these later!).

Melt Butter & Remaining Marshmallows. In a large saucepan, melt butter then add the remaining mini marshmallows and stir over medium-low heat until the marshmallows are smooth and melted. The mixture will be gooey!

Add Strawberry Powder, Vanilla & Salt to the marshmallow mixture and stir to combine.

Combine Marshmallow Mixture With Cereal. Working quickly, pour the strawberry marshmallow mixture over the cereal and stir in the reserved 1 cup of marshmallows and 1 cup chopped freeze-dried strawberries. Stir to evenly combine.

Pat the mixture out into your prepared pan using gentle pressure so you don't overly compact the rice krispie treats. Top with a few more pieces of freeze-dried strawberry and marshmallow, for garnish.

Cool, Slice & Store. Let the cereal bars cool at least 30-60 minutes to set. Use a sharp knife to cut them into bars and store leftovers in an airtight container or bag at room temperature 2-3 days.
