Instructions
1. Heat oven to 350°F and line two baking sheets with parchment; whisk flour, cocoa, baking soda, and salt in a bowl.
2. Beat butter and brown sugar until fluffy, add egg and vanilla, then alternate dry ingredients with buttermilk until smooth.
3. Pipe or scoop 1.5–2 tablespoon mounds onto sheets, spacing 2 inches apart; smooth tops with damp fingertip.
4. Bake 8–10 minutes until cakes spring back and tester shows moist crumbs; cool 5 minutes on sheets, then transfer to racks.
5. Make marshmallow buttercream: beat fluff, butter, powdered sugar, vanilla, and salt until fluffy.
6. Or make orange buttercream: cream butter, sugar, vanilla, pinch of salt, splash of cream, then tint orange.
7. Pair similar-sized cakes, pipe filling onto one, sandwich with another, then decorate with sprinkles, candy eyes, or gel.
Notes
For darker cakes, add 1–2 teaspoons black cocoa.
Chill batter 10 minutes before scooping for taller domes.
Avoid overbaking to keep cakes soft and plush.
Use buttercream for travel stability; marshmallow fluff is best for same-day serving.
Store assembled pies airtight at room temp 1 day, or refrigerate 2–3 days.
