I had SO much fun making this that I had to share it with ya'll!
I have never tried making cake in a mason jar before, but it totally works, and is SO cute looking!
Go here for the recipe, and I'll give you my tips to make it turn out great!
Start with some yummmmmmy looking cake batter, divided into several bowls.
(I used neon food coloring for all my colors)
Spoon in one layer at a time, filling your jar about halfway with all your colors. Like so:
TIP: the first time I tried "layering" my batter in the jars, it was WAYYYY too runny. Add about 2 tsp. cornstarch, and 1-2 Tbs. of flour to each bowl. It will thicken it up, and make it much easier to "layer".
Bake at 350 for 20 minutes, and top with frosting and sprinkles when cool.
FYI: I used half pint mason jars.
(because I love stuff that is miniature!)
