In a large microwave safe bowl, combine the marshmallows with the vegan butter and coconut oil.
Microwave in 30 second intervals, stirring in between, until mixture is smooth and melted down.
Stir in the freeze dried raspberries, followed by the crispy rice cereal.
Mix until everything is well combined.
Line a 9x9 baking pan with parchment or wax paper, and transfer the rice krispie mixture into the pan. Press down using your hands or the back of a spoon to make sure everything is even and compact.
Let the rice krispie treats set for about 30 minutes.
Once the treats are set, you can cut them into squares or cut them with a heart-shaped cookie cutter. You can press the scraps together and make more cut-out treats!
Melt the vegan chocolate down in the microwave in 30 second intervals, and transfer to a zip-top baggie. Cut the corner, and drizzle the chocolate on top of the treats. Sprinkle on additional freeze dried raspberries.
Allow chocolate to set, then serve or store in an airtight container until ready to enjoy.
