Whisk together until well combined.

-
Layer wisely: Alternate layers of cake and frosting in the jar for beautiful visual appeal and balanced flavors. Consider adding fruits or other fillings between the layers.

Don’t overfill: Leave some space at the top of each jar. This allows for expansion during baking and prevents messy overflow.

Seal tightly: If you plan on storing your jars, ensure they are sealed properly to maintain freshness. Use airtight lids if possible.

Common Mistakes to Avoid

-
Overmixing the batter: This can create a tough cake. Mix until just combined to maintain a light and fluffy texture.
