Line a 9x13 baking dish with parchment paper.
Combine the chai spice ingredients in a small bowl and set aside.
Melt the vegan butter in a large pot over medium heat. Add the marshmallows and stir until melted - it will take about 10 minutes for them to melt completely, just keep stirring. Once the marshmallows are done melting, stir in the chai spice and vanilla extract. Remove from the heat.
Add the rice krispies a few cups at a time and stir until combined. Transfer the mixture to the baking dish and press it down. Allow to cool for 30 minutes.
Melt the chocolate chips in the microwave or over a double broiler and spread out over the rice krispies. Sprinkle with sea salt and place in the fridge for 1 hour.
Remove from the fridge and cut into squares. Store in an air-tight container on the counter for 2-3 days or in the fridge for up to 1 week.
