Make Bunny Butt Cupcakes: fluffy vanilla cupcakes topped with grassy buttercream and fondant bunny rumps for a playful party treat.
Sift the dry ingredients together in a large bowl — all-purpose flour, sugar, baking powder and a pinch of baking soda — until light and aerated. In a separate medium bowl cream the room-temperature butter with eggs, vanilla, sour cream and whole milk until smooth and homogeneous; fold the wet into the dry just until combined so the batter remains tender and slightly ribbon-like. Spoon or divide the pale yellow batter into bright green-and-white chevron paper liners, spacing them evenly; bake until the centers spring back and let the cupcakes cool completely on the painted pine surface so they’re ready for decorating.

Beat the softened butter until light and very fluffy, then add confectioners’ sugar a cup at a time, scraping the bowl between additions. Add a splash of whole milk to reach a pipeable, ribbon-like consistency, then fold in vanilla and three drops of green food coloring until the buttercream turns a vibrant grassy hue. Reserve a small amount loose in a bowl for spatula work, then transfer the rest to a piping bag fitted with a 133 grass tip so you have both a spreadable layer and a strong, textured piping supply for the final meadow effect.
Use an offset spatula to press a thin base layer of green buttercream onto each cooled cupcake to secure the fondant elements. Pipe grass around the outer edge with the 133 tip, then place a small, sugar-dusted fondant body at the center: roll smooth white fondant into a rounded mound for the bunny rump, wet the join points and press gently. Form tiny feet by cutting small circles from a thin sheet of fondant using the back of a piping tip, elongate them slightly into ovals, tint a pinch of fondant pink for the toe pads and attach with a touch of water. Roll small fondant balls, wet and roll in white sanding sugar for shimmer, and finish each bunny with a fluffy white pom‑pom tail pressed into the center. Fill any gaps by piping additional grass to create a dense meadow, scatter a few pastel candy eggs around the cupcakes in the chevron wrappers, and present them once the tiny fondant pieces are firmly set.
