📋 FREQUENTLY ASKED QUESTIONS
Can I just bake my cake in the Jar?
Mason jars are not oven proof and should not be used for baking. Sorry!
Why wouldn't I bake my CannaButter or Canna Oil into my cake mix?
Because one box of cake mix can make up to 12 mason cake jars, it's easier to manage the dosing by adding it in at the end. This also allows you to build one jar at a time when you're ready to eat it.
What's the best way to get my frosting into the jar without getting the sides gross?
The easiest option is to add a spoonful of frosting to the middle of the cake layer and then spread it out when you slide the next layer of cake on top. You can also spoon your frosting into a plastic baggie. Snip the corner off and squeeze it in.
Can I make homemade cake and/or frosting?
Of course! Choose your favorite recipes and get cooking!
