For the Cupcakes: 
2 Preheat the oven to 350F. Line a cupcake tin with cupcake liners. 
3 In a small bowl, whisk together the flour, baking powder, and salt. 
4 Add the butter to the bowl of an electric mixer and beat it until creamy. Add the sugar and beat with the butter in high speed until fluffy, 2 to 3 minutes. Add the egg and egg white, mixing well on medium speed until combined. Scrape down the sides of the bowl if needed. Add the oil and vanilla extract, beating on medium speed for another minute. With the mixer on low speed, add half the dry ingredients and blend. Pour in the milk and blend. Add the other half of the dry ingredients and mix on medium speed until the batter is combined. Use a large spatula to gently stir in the sprinkles. 
5 Fill the cupcake liners two-thirds full. Bake until the tops are set, 10 to 20 minutes. Let cool completely before frosting. 
For the Vanilla Cream Frosting: 
8 Add the butter and cream cheese to the bowl of an electric mixer and beat on high speed until creamy and combined. With the mixer on low speed, slowly add the powdered sugar. Beat until the sugar is incorporated, and then add the vanilla extract. Scrape down the sides of the bowl if needed. Beat the frosting on high speed for 2 to 3 minutes, until fluffy and creamy. If the frosting seems too thick, beat in the milk for 1 to 2 minutes, until combined. Frost the cupcakes and top them with the sprinkles.
