# How To Make It:
01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners.
02 - Sift together cake flour, baking powder, baking soda, and salt in a medium bowl. Whisk to combine and set aside.
03 - Beat butter on medium speed for 1 minute until smooth. Gradually add granulated sugar and beat for 2–3 minutes until light and fluffy.
04 - Lightly beat egg in a small bowl. On low speed, slowly add egg to butter mixture and mix until fully incorporated. Blend in vanilla extract.
05 - On low speed, add one-third of dry ingredients to butter mixture and mix until combined. Add half the buttermilk and mix. Repeat with another third of dry mix, remaining buttermilk, and final third of dry ingredients. Scrape bowl as needed and avoid overmixing.
06 - Stir together white vinegar and pink gel food coloring in a small cup. On low speed, pour mixture into batter and mix until evenly tinted throughout.
07 - Divide batter evenly among 12 liners, filling each approximately two-thirds full. Tap pan gently to release air bubbles.
08 - Bake for 18–22 minutes until a toothpick inserted into the center comes out clean or with a few moist crumbs.
09 - Let cupcakes rest in pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.
10 - Beat butter on medium speed for 1 minute until creamy. Gradually add 2 cups powdered sugar on low speed, then increase to medium and beat until smooth for about 2 minutes. Add vanilla, cream, and salt. Beat on medium-high for 1–2 minutes until light and fluffy. Add more sugar for stiffness or more cream for softness. Mix in pink food coloring if desired.
11 - Transfer buttercream to a piping bag with preferred tip or use a small offset spatula. Frost each cooled cupcake. Decorate with sprinkles, edible pearls, or pink sanding sugar if desired.
