Prepare a loaf pan by spraying lightly with cooking oil and lining with parchment paper so the paper sticks to the pan. Then lightly spray the parchment paper to prepare for the treats.
Roughly chop or crush the ⅓ cup dehydrated strawberries and add to a large bowl. Measure out 3 cups chocolate Rice Krispie treats.
Melt 3 Tbsp butter in a medium pot. Remove from the heat and add marshmallows. Stir consistently until marshmallows begin melting. Once marshmallows have started to dissolve, add pot back over low heat and continue stirring until fully melted.
Add the chocolate Rice Krispies and dehydrated strawberries. Stir so everything is coated.
Pour half the mixture into the prepared loaf pan. Scatter half the brookside chocolate candy throughout then layer on the remaining treat mixture.
Don’t use your hands, the marshmallow may be hot! Using another piece of parchment paper, or the flat bottom of a glass, press lightly into the corners and flatten the treats. You can also give a light dusting of cooking spray to your surface to help keep it from sticking.
Press remaining brookside chocolate candies into the top of the rice krispie treats. Allow to set for at least an hour.
