Chocolate Valentine’s Day Cupcakes with the “Best” Buttercream Frosting Ever

Easy semi-homemade chocolate cupcakes with the best ever buttercream frosting topped with Valentine’s sprinkles. A delicious treat for your “Galantine’s” or Valentine’s Day celebration. 

  • Total Time: 0 hours
  • Yield: 12-18 cupcakes 1x



1 Package Devils Food Cake Mix

11/2 cups sour cream

1/4 cup melted butter, cooled

2 large eggs

1 tsp. vanilla extract


Preheat the oven to 350.

Line cupcake pans with baking cups, set aside.

In the bowl of a stand mixer, beat the cake mix, sour cream, cooled butter, and eggs on low until just mixed, then turn the mixer on medium and beat for 2 minutes.

Then add vanilla and mix again to incorporate.

Pour batter into baking cups, do not fill more than 2/3 full. Bake cupcakes for 20-25 minutes, check the cupcakes at 20 minutes with a toothpick.

Once the toothpick comes out clean remove from oven and cool a couple of minutes on a wire rack, then remove cupcakes from pan and finish cooling the cupcakes on the wire rack.

Frost and add sprinkles.


Sour cream: When I made the original recipe which a friend gave me years ago it called for 16 oz. sour cream. I cut it down this time to 1 1/2 cups because it was all that I had and they still came out moist and delicious.

Buttercream frosting can be replaced with the frosting of your choice. Sprinkles are optional as well.

Depending on the size of your cupcake pan and lines you will get anywhere from 12-18 cupcakes.
