Buttercream turned to soup.

Butter was too warm. Chill 10 minutes, beat again. If it looks curdled, keep beating.

Can I use boxed cake?

Yes. The decorating is the course. Chill the layers before you stack.

Frosted buttercream cake: 2 days cool room or 4 days fridge. Serve at room temp.

Parchment in the bottom so the layer actually leaves the pan.

01Prep pans like you mean it

Grease, line the bottoms with parchment, dust with flour, tap out the extra. Weigh the batter into the two pans so they match. Bake at 175°C / 350°F until a toothpick has a few moist crumbs — not wet batter, not bone dry.

Cool 10 minutes in the pan, turn out, cool fully. Wrap and refrigerate 1 hour. Warm cake shreds when you frost it.

02Level with a sawing motion

Serrated knife, cake on the turntable, blade level with the equator. Rotate the cake into the knife. Do not press down.
