Cupcake Instructions
- Preheat oven to 325°F (163°C). Line a cupcake tin with cupcake liners.
- In the bowl of a stand mixer fitted with the paddle attachment, beat butter and sugar until light and fluffy, about 2 minutes.
- Add the egg and egg white, mixing until combined. Add vanilla and sour cream, then mix again. The batter may look curdled at this stage.
- In a medium bowl, whisk together cake flour, baking powder, baking soda, and salt.
- Gradually add dry ingredients to wet, alternating with buttermilk. Start and end with the dry ingredients.
- Fold in chopped mini eggs until just combined.
- Scoop batter into prepared liners, filling each about 2/3 full.
- Bake for 18 minutes, or until tops spring back when lightly touched. Cool cupcakes in the pan on a wire rack.
Buttercream Instructions
- In a stand mixer, beat butter until fluffy.
- With mixer on low, gradually add powdered sugar, one cup at a time.
- Add sifted cocoa powder, then mix in heavy cream and vanilla.
- Beat on high speed for 3–4 minutes until fluffy, then mix briefly on low to remove air bubbles.
- Pipe chocolate buttercream swirls onto cooled cupcakes and top with sprinkles and extra mini eggs.
Notes
- Make sure all ingredients are at room temperature for best results.
- Do not overbake the cupcakes—check at the 16-minute mark.
- Cool cupcakes completely before frosting to prevent melting.
