Preheat the oven to 350°F and line a rimmed baking sheet with parchment paper. Spread the 3/4 cup flour in an even layer and bake for 5 minutes then set aside to cool.
In the bowl of a hand or stand mixer fitted with the paddle attachment, or in a small bowl with a whisk, cream the 1/4 cup butter with the 2 tbsp powdered sugar and 2 tbsp granulated sugar until its light and fluffy about 1 minute.
Add in the 1/2 tsp vanilla extract and the 2 tsp milk and mix lightly. Add in the 3/4 cup cooled heat treated flour, pinch of salt, and the mini chocolate chips. Mix well and place in the fridge for 20 minutes.
Make the cupcakes
Line a muffin tin with 12 cupcake liners and set aside.
In a medium size bowl combine the 1 and ¾ cup cake flour, 1 tsp baking powder, ¼ tsp baking soda, and ¼ tsp kosher salt. Whisk until combined and set aside.
In the bowl of a hand mixer or stand mixer fitted with the paddle attachment, cream the ½ cup butter for 1 minute on medium speed. Scrape down the bowl and add 1 cup sugar. Mix on medium speed for 2 minutes until light and fluffy.
Scrape down the bowl and add the egg, 2 egg whites and 2 tsp vanilla extract. Mix for 1 minute on medium speed.
With the mixer on low speed, add in 1/3rd of the dry ingredients, mix, then add half of the buttermilk and alternate (mixing in between) ending with the dry ingredients. Mix only until combined. Do not overmix.
In a small bowl combine the 1 cup mini chocolate chips and remaining 2 tsp flour. Mix to coat the chocolate chips evenly. Pour the chocolate chips into the batter and mix lightly by hand.
Using a cookie scoop, scoop batter halfway up in a muffin liner.
Remove the cookie dough from the fridge and using a teaspoon, scoop at least 12 small balls. Drop each one into the center of the batter then top with more batter until it reaches 3/4 of the way full. Its ok if its a little more!
Bake for 18-19 minutes, then remove and cool completely on a wire rack.
