In a small bowl, prepare your protein slurry by mixing 50g protein powder with the 80ml almond milk until it becomes thick.
In a large saucepan, heat the butter over medium heat until it has melted slightly
Add the marshmallows to the saucepan and stir continuously until they have melted
Stir in the protein slurry, and the rest of the protein powder and continue mixing until they are well incorporated into the melted marshmallow mixture
Remove the saucepan from the heat and add the Rice Bubbles and soy protein crisps, mixing until they are well combined with the mixture
Line a 9x13 inch baking pan with parchment paper and pour the mixture into the pan
Using the back of a spoon or your hands, press the mixture into the pan until it is even and compact
Place the pan in the refrigerator for 1-2 hours to allow the mixture to set
(Optional) Cut out 18-20 heart shapes from the mixture using a heart-shaped cookie cutter OR cut into 12-16 squares
In the microwave or over a bain-marie, melt the white chocolate chips over low heat and add a few drops of pink food coloring to achieve the desired color
Drizzle the melted white chocolate over the Rice Crispie treats and let it set for 10 minutes in the fridge
Serve and enjoy!
