Making Cupid’s Arrow Cupcakes is straightforward if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
2. Mix Dry Ingredients: In a large bowl, combine the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Whisk until well mixed.
3. Combine Wet Ingredients: In another bowl, whisk together the egg, milk, vegetable oil, and vanilla extract.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined.
5. Add Boiling Water: Carefully stir in the boiling water. The batter will be thin; this is normal!
6. Pour Batter: Pour the batter evenly into the prepared cupcake liners, filling each about 2/3 full.
7. Bake: Place in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool: Once baked, remove from the oven and allow the cupcakes to cool in the pan for about 10 minutes. Then, transfer them to a wire rack to cool completely.
9. Prepare Frosting: In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, mixing until smooth. Add the heavy cream and beat until fluffy. If desired, add food coloring to achieve your desired hue.
10. Frost the Cupcakes: Once the cupcakes are completely cool, frost them generously with the buttercream frosting.
11. Decorate: Finally, sprinkle heart-shaped decorations on top for a romantic touch.
