Preheat oven to 375 degrees Fahrenheit.
In a large mixing bowl, add in the ½ cup of butter and granulated sugar. Using a hand or stand mixer, beat until smooth and creamy.
Add in the eggs and vanilla extract.
Mix well and add the white vinegar.
Add in the salt, cocoa powder and baking soda.
Once mixed, add in the vegetable oil and buttermilk.
Mix until well combined and add in the food coloring.
Add in as much red food coloring as needed until the desired red is achieved.
Slowly add in the flour in ½ cup increments, mixing in between each time.
Line 2 muffin tins with cupcake liners (this recipe will yield about 20 cupcakes)
Add a Tbsp. of the cupcake batter to each liner.
Place one chocolate truffle in the middle of the batter.
Add in more batter until the liners are ¾ of the way full.
Bake at 375 degrees Fahrenheit for 13-16 minutes. ***Be sure to check with a toothpick by placing the toothpick in the middle of a cupcake. If the toothpick comes out clean of red, they are done!
Allow cupcakes to cool completely.
