First choose the number of servings and how you will cut them. Then scale the batter by the ratio of pan areas if the batter depth stays the same.

At 10 cm edible height, PEK’s volume model gives about 20–25 small event servings from a 20 cm round cake, 30–36 from 24 cm, 35–42 from 26 cm and 41–49 from 28 cm when serving…

Calculate each tier separately. For round pans at the same planned batter depth, use factor = new diameter² ÷ original diameter². If the target tier is also taller or shorter, multiply by the height ratio.
To keep roughly the same batter depth, compare the base areas: round = π × r² and square = side². Recipe factor = new pan area ÷ original pan area.
For two round pans when you want the same approximate batter depth, use: scaling factor = (new diameter ÷ original diameter)². Multiply the main ingredients by that factor.
An acetate cake collar is a smooth transparent food-contact strip placed inside a cake ring for mousse cakes and other chilled desserts.
Convection is not universally better: moving air increases heat transfer. When converting a conventional-bake recipe, about 25°F (15°C) lower is a common US starting point, while some manufacturers use about…
Cut parchment to fit the pan, keep loose edges away from heating elements and follow the maximum temperature printed by the manufacturer.
A wrinkle usually appears because the collar is not flat and stable before or during filling: it has a crease, a raised seam, poor contact with the ring, or an unsupported section above the ring that waves.
An acetate cake collar should reach at least the planned finished height of the mousse cake.
For most layer cakes and loaf-style cakes, a light-coloured metal pan is the most predictable starting point because it transfers heat quickly without over-browning the edges as readily as a dark pan.
To reduce foam, keep an immersion blender head below the surface or limit the vortex in a countertop blender.
Do not multiply baking time by the same factor used to scale the ingredients. If scaling the recipe into a larger pan keeps batter depth about the same, keep the recipe temperature and start checking around the…
For most home baking, start with a reliable digital scale, two adequately sized bowls, a whisk, a firm spatula, one or two useful pans, baking parchment and a cooling rack.
For most home baking, a digital kitchen scale with 1 g resolution and roughly 3–5 kg capacity is practical. Weigh very small doses, where 1 g is a large relative error, on a separate 0.1 g scale.
Do not judge an oven from one reading. Place the sensor near the centre of the rack, observe at least three complete heating cycles after stabilisation, and average evenly timed readings.
