Last week I came up with this kid-friendly project. It’s super easy and combines both baking and crafting. Ready to get started?! First off, you’re going to need a few supplies. You’ll have to decide whether you want to do all of one kind of jar, or if you want to do three of each (one box of cake mix makes (9) ½ pint mason jar mini cakes). Since I wanted to show you all of them, here’s what you’ll need to make three of each.

Ingredients

  • 1 box white cake mix
Buttercream Frosting
  • 4 Cups Powdered Sugar
  • 1 1/2 Cups Butter - room temperature
  • 2 Tbsp Heavy Cream
  • 1 Tbsp Vanilla Extract
  • 1/4 tsp salt

Instructions

  • Make the cake batter per the package instructions.
  • Once the batter is ready divide it evenly in between three bowls. Add a few drops of food coloring into two of the bowls, coloring one green and the other orange.
  • Pour the batter into the mason jars, filling each to the halfway mark (don’t go any further, or your cakes will overflow). You will end up with three green, three orange and three white.
  • Set the jars onto a rimmed baking sheet and place in the center of the oven. Bake at 350 degrees for 20 minutes. BE CAREFUL! If you over-bake these they will become brown… so watch them up until the 20 minute mark and remove them immediately!
  • Place the baked cakes onto a wire rack to cool completely (about 30-40 minutes). If the cakes have risen too much, you can always take a knife and cut off the excess cake so that there is enough room to frost them.
  • Meanwhile to prepare the frosting, in the bowl of a stand mixer, beat together butter, vanilla, heavy cream and salt. With mixing speed on low, gradually add powdered sugar. Turn the speed up to high and beat until fluffy, about 5 minutes.
  • Remove bowl from stand and divide frosting into three bowls. Color one orange, one black and leave the other white. Scoop into prepared piping bags. Set aside.
  • When cakes have cooled, decorate jars. Let the ink and glue set for 5-10 minutes before frosting.
  • Frost the cakes as desired and garnish with sprinkles. If you are giving these as a gift, you can screw on lids and decorate the tops.
  • To store, seal and place in refrigerator for 2-3 days. Enjoy!

  3. You could also put some seedless red jam in the middle by scooping some of the cake out and before frosting for the members of the family or trick or treaters who like the extra gore factor

    1. Hi Jess! If you’re using a boxed mix you can go ahead and follow the instructions for “high altitude” baking on it, but I live at about 4,300 ft. and rarely need to do so. Hope that helps!

    1. Of course! It may be too soft to pipe once you add the food coloring, but I’m really not sure. If you give it a try, please let me know how it turns out!

  4. do you grease and flour jars or not and do you put water in bottom of pan when baking to keep from burning and if they are glass some cake mixes says cook at 325

    1. Hi Sandy, I didn’t but you can definitely turn your oven down to 325. Adding water isn’t really necessary but it might help prevent browning (“discoloration”) at the bottoms of the jars (if that’s important).
