Notes
- This recipe covers a 9×13 sheet cake, a 2‑layer 8″ or 9″ round cake, or 12 generously frosted cupcakes (or up to 24 modestly frosted cupcakes) :contentReference[oaicite:1]{index=1}.
- For a stiffer frosting, add an additional ½–1 cup powdered sugar :contentReference[oaicite:2]{index=2}.
- Avoid using natural peanut butter that separates—it's too oily and can lead to grainy or runny frosting :contentReference[oaicite:3]{index=3}.
