  5. Stir constantly until the chocolate chips are just melted.
  6. Remove from heat and set aside.
  7. In the bowl of a stand mixer fitted with a paddle attachment, combine eggs, buttermilk, oil, and vanilla extract on medium speed, about 2 minutes.
  8. Reduce mixer to low speed, and slowly pour in chocolate mixture.
  9. Beat until combined, about 2 minutes.
  10. Gradually add the dry ingredients.
  11. Increase mixer to medium speed, and beat for 2 additional minutes.

  15. Flip the cakes onto a cooling rack and let the cake layers cool completely.

  4. Continue mixing until combined.
  5. In a small bowl, stir the Dr Pepper and vanilla extract until combined.
  6. Slowly pour the Dr Pepper-vanilla mixture into the mixer bowl.
  7. Increase the mixer speed to high to thin the frosting, about 1 minute.

To assemble:

  1. Place the first cake layer on a flat plate.
  2. Spread 1 cup of frosting on top.
  3. Top with the second cake layer.
  4. Spread remaining frosting evenly on the top and sides of the cake.
