Prepare Chocolate Shells: Melt chocolate chips and coconut oil in the microwave in 30-second intervals, stirring until smooth. Dip each waffle cone halfway into the melted chocolate, then place on parchment paper to set. Repeat for all cones.
Soften Ice Cream: Let vanilla ice cream sit at room temperature for 5-10 minutes to soften slightly.
Fill Tacos: Carefully fill each chocolate-coated waffle cone with vanilla ice cream.
Add Toppings: Sprinkle with sprinkles and drizzle with chocolate sauce. Serve immediately.
