Cup of Yum
1. Preheat oven to 350°F. Line 2 12-cup standard muffin tins with paper liners.
2. In the bowl of a stand mixer, fitted with the paddle attachment, or with a hand mixer in a large bowl, beat together the cake and pudding mixes, sour cream, oil, eggs, vanilla and water.
3. Beat for about two minutes on medium speed until well combined. Fold in chocolate chips. Be sure to scrape down the sides of the bowl and give them batter one final mix.
4. Using a large cookie scoop, distribute the batter between 24 muffin wells; about 3 tablespoons of batter per well.
5. Bake in preheated oven for 18-22 minutes or until the tops of the cakes spring back when lightly touched. Allow cupcakes to cool inside muffin tins for about 10 minutes.

7. Once the cupcakes have cooled, prepare the sparkling hearts and buttercream.

For the Sparkling Hearts:

2. Dip one side of the heart into the melts and use an offset spatula to remove any excess melted candy, immediately sprinkle the heart with sparkling sugar.
3. Place the dipped heart on prepared sheet and allow the candy to harden.
4. Repeat with remaining CupidMallows.

3. Add in vanilla and mix on low speed until incorporated.
4. Turn the mixer back up to medium-high speed and beat the buttercream for an additional 5 minutes. If the buttercream is too thick, add in a bit of milk, one teaspoon at a time until you reach the desired consistency.
