Halloween Themed Mason Jar Mini Cakes

Halloween Themed Mason Jar Mini Cakes!! The cutest little cakes that kids will love!
Hello! I’m Natalie and I blog over at Life {Made} Simple. I’m so excited to be here today! Since Halloween is fast approaching, I thought I’d share with you a fun little baking/craft project. These mason jar mini cakes are easy to make and only require a few materials! Let’s 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) 1/2 pint mason jar mini cakes). I like variety, so here’s what you’ll need to make three of each-
Halloween Themed Mason Jar Mini Cakes!! The cutest little cakes that kids will love!


(3) 1/2 pint mason jars
1 black Sharpie paint pen
6 googly eyes
super glue
black sprinkles
green & black food coloring
(3) 1/2 pint mason jars
1 black Sharpie paint pen
green sprinkles
green and orange food coloring
(3) 1/2 pint mason jars
1 box of 2″ gauze
6 googly eyes
super glue
white sprinkles

1 Box white cake mix*

1 Recipe buttercream frosting
4 c. powdered sugar
1 1/2 c. (3 sticks) butter, room temperature
2 tbsp. heavy cream
1 tbsp. vanilla extract
1/4 tsp. salt

3 Piping bags with desired tips


1. Now that we’ve decided what we’re making, lets get the cake batter made! *You can always use your own recipe, but a store bought mix is a quick and easy alternative. 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.


2. 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!

3. 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.

4. 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.

5. When cakes have cooled, decorate jars. Let the ink and glue set for 5-10 minutes before frosting.

6. 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!

  1. Oh my gosh!… I LOVE these! This post was made for me. :):) My little head was thinking about making something like this because yes, I love cake hahah but now my mind doesn’t have to think about it anymore because I can enjoy yours! Thanks for sharing. I love your blog and would love to share something of yours on my website sometime!

  2. I LOVE these. I cook dinner once a week for my adult children and their families (to stop over, and take home to eat). I’ll be making these this week for sure! I’ll make all 3 designs. I wish the lids wouldn’t mash the frosting but that’s still OK. Thanks SO much for sharing

  3. I want to make these but have read it is very dangerous to put mason jars in the oven due to possibility of thermal shock and the jars exploding/cracking. Anyone know?

  4. Has anyone double the recipe for the pint jars? And how did it work out? I was unable to find half pint jars with blank sides to decorate but did find some full pints… will be giving them a try ¯\_(ツ)_/¯

      1. Honestly I’m not sure the recipe needed doubled. I added 10-15 minutes to the cook time but the jars over flowed and I had to scoop some out to fit in the icing. I think they would have been ok without doubling he batter and just have a bit more icing, but they were a big hit!
