FAQ

Can I use gel food coloring instead of liquid?

Yes, gel coloring is more concentrated. Use 5-8 drops per color instead of 10-20 to avoid over-darkening. Gel colors produce more vibrant polka dots and won't thin the batter.

What if my polka dots aren't visible after baking?

Circles likely sank too deep into batter or white cake rose too much. Press circles gently so they sit partially above batter surface. Don't overbake white cake layers or they'll expand excessively.

Can I freeze this cake?

Yes, freeze unfrosted cake layers up to 3 months wrapped tightly, or frosted cake up to 2 months. Thaw in refrigerator 4-6 hours before serving.
