You don't have to make both flavors, you can easily do just one or the other!
Preheat the oven to 350°F and line a 24 cup mini cupcake pan with mini cupcake liners.
In a large bowl, whisk together the melted butter and sugar until smooth. Add in the egg and vanilla bean paste and whisk until fully incorporated.
In a separate bowl, sift together the flour, baking powder, and salt.
Mix half of the dry ingredients into the wet ingredients, then add in the milk. Once incorporated, add in the remaining dry ingredients and mix until just combined. The batter should be thick.*
Fill each cupcake liner about ¾ full (about 1 tablespoon of batter).
Bake at 350°F for 10-12 minutes or until a cake tester comes out clean.
Remove from pan and let cool on wire rack. Let the mini vanilla cupcakes cool completely before frosting.
In a large bowl using a handheld or stand mixer fitted with a paddle attachment, cream the room temperature butter and powdered sugar until smooth.
Add in the vanilla bean paste and beat the frosting on high for 4-5 minutes until lightly and fluffy.
If needed, add in cream 1 tablespoon at a time until desired consistency is reached.
Frost the mini vanilla cupcakes with vanilla buttercream and garnish with rainbow sprinkles if desired!

Melt the dark chocolate and let cool almost to room temperature. It should be melted but cool to the touch. I prefer to melt the chocolate in the microwave in intervals of 20 seconds, stirring each time.
In a large bowl using a handheld or stand mixer fitted with a paddle attachment, cream the room temperature butter and powdered sugar until smooth.
Add in the cocoa powder and mix until fully combined.
Set the mixer to low speed and slowly drizzle in the melted chocolate until it's fully incorporated into the buttercream. Beat the frosting on high for 4-5 minutes until light and fluffy.
If the frosting in too thick, add in 1 tablespoon of cream at a time to thin it out a bit.
