Instructions:
- Preheat oven to 350°F (175°C). Grease and flour a 9-inch cake pan.
- Cream butter and sugar until pale and fluffy. Beat in eggs and vanilla.
- Alternatingly add dry ingredients and buttermilk, mixing until just combined.
- Bake for 25 minutes or until a toothpick comes out clean. Cool completely.
- Pulse the cooled cake in a food processor for 10 seconds until it resembles fine sand.
- Whip the frosting ingredients (butter, powdered sugar, heavy cream, and vanilla) together until smooth and velvety.
- Add frosting to the cake crumbs one tablespoon at a time.
- Fold gently with a spatula until the dough holds its shape when squeezed—it should feel like soft play-dough.

- Chill the balls in the freezer for 15 minutes to firm up.
