- Cookie Cutters
- Piping Bag and Tips
- Paper Towels or Cloth
Types of Jars for Jar Cakes
The main part of mason jar cakes is putting them in mason jars! But really, you can use any clear jar you want.Ā
For the majority of my cakes, I used these jars. Theyāre 12 oz and I think just the right size for a personalized cake in a jar. But you can go bigger or make mini cakes in a jar too. It helps to have wide mouth jars that donāt have a lot of embellishments or writing on them, but itās not necessary.Ā
You can see here I used some leftovers in super small mason jars I had on hand and they still turned out super cute.
How to Make
Step 1: Make and Bake Cake
The nice thing about this is you can use your favorite cake recipe! Iām using a basic white cake recipe and adding sprinkles and baking in a 7 x 11 or 9 x 13 inch cake or jelly roll pan. I lined the baking pan with parchment paper and then buttered and floured so the cake wouldn’t stick. Then, prepare cake batter according to instructions and pour into the prepared pan and bake for 8-12 minutes.
Similar to these lunchbox cakes, the smaller the pan the thicker the cake layers.Ā I wanted to have different flavors so I did half batch of 3 different kinds of cake and it make about 15 mason jar cakes.Ā
Step 2: Make Frosting
You can use whatever frosting recipe you like! For the funfetti birthday cakes in a jar, I used a half batch of my basic American Buttercream. It helps to put the frosting into a piping bag, but you can also spoon it into the mason jars.
Step 3: Ā Cut and Layer Cake
Now for the fun part, cutting and layering the cake into the jars. I used these circle cookie cutters and found one that matched the opening of my jar.
Be sure to test the size of your cookie cutters to the size of the openings and if they taper. The jars I have taper a bit at the bottom, so I used a smaller size for the bottom layer.Ā
Then, add your first layer of cake. After that, pipe or spoon in the frosting layers. Add any optional sprinkles, crushed cookies, or whatever else you want to use. Then, repeat the process until you get to the top of your jar, being sure to clean up anything that splatters on the sides of the jar with a paper towel or cloth between each layer so it stays looking clean.
And, don’t waste the extra cake! You can still use it for layers in the jar cakes, but it will have a more rustic look to it rather than the clean cake rounds from using the cookie cutters.Ā Of course, you can also snack on it instead, or use the leftovers for a few cakesicles.Ā
Thatās it! Add any optional sprinkles, etc. to the last layer and close up your jar and theyāre ready to be served, gifted, or stored!Ā
Tips and Tricks

- Be sure to test the size of your cookie cutters to the size of the openings and if the jars taper. My mason jars tapered at the bottom so I had to use a smaller size for the bottom layer.Ā

Cake in a Jar Recipe
Equipment
- Parchment Paper
- Sheet Cake or Jelly Roll Pan
- Paper Towels or Cloth
INGREDIENTS
Cake
- 1 Ā¼ cup all-purpose flour
- 2 tbs cornstarch
- Ā½ tsp salt
- 1 tsp baking powder
- Ā½ cup unsalted butter room temperature
- Ā¾ cup granulated sugar
- 2 large egg whites room temperature
- 2 tbs canola oil
- ā cup milk room temperature
- 1 tsp vanilla
- Ā¼ cup rainbow sprinkles
Frosting
- 1 stick unsalted butter omit added salt if using salted butter
- 1.5-2 cups powdered sugar
- 1/2 tsp vanilla
- 1-2 tablespoons milk or cream
- Pinch salt
Sprinkles
Instructions
Cake
- Preheat oven to 350ā. Grease a 9x13 or 7x11 inch jelly roll pan with butter or vegetable shortening and line with parchment. Then re-grease and flour the parchment lined pan. Set aside.
- Whisk together the flour, cornstarch, baking powder, and salt in a medium sized bowl.
- Using the beater attachment of a standing mixer, or using a hand held mixer with a large bowl, cream together the butter and sugar 3-4 minutes. It should be light and fluffy and pale yellow.
- Add egg whites one at a time, fully incorporating between each egg white. Then, mix in the oil and vanilla.
- With the mixer on low, alternate adding the dry ingredients in 3 additions and the milk in two additions, starting and ending with the dry ingredients.
- Mix until the flour is just incorporated. Do not overmix or the cake can get dry/tough.
- Using a spatula, gently fold in the sprinkles.
- Pour the cake into the prepared pan and bake for 8-12 minutes until a toothpick comes out clean when piercing the center of the cake. Let cool completely.
Frosting
- Using a standing mixer or a hand held mixer in a large bowl, whip the butter 3-4 minutes until creamy and pale yellow.
- Add powdered sugar and vanilla mix on low until it looks crumbly.
- Turn up the speed and mix another 3-4 minutes until light and fluffy.
- Mix in milk or cream until desired consistency is reached. Add to a piping bag fitted with a large tip.
Assembling Cakes in a Jar
- Once the cake has cooled, use circle cookie cutters to cut out circles that fit the size of your jars. Be sure to check for tapering or jars that are smaller or wider at the top and cut out circles accordingly.
- Alternatively, you can just break off pieces of cake and place in layers in the jar for a more rustic look. This also a great way to use the extra cake from cutting out circles.
- Then, add your first layer of cake to the jar. Carefully pipe a layer of frosting on top of the cake. You can also spoon the frosting into the jars. Be sure to keep the inside of the jars clean by whipping off any excess frosting or cake crumbs from the insides of the jars with a paper towel or cloth after each layer.
- Add a layer of optional sprinkles, crushed cookies, caramel or whatever else you want to use. Then, repeat the process of layering cake, frosting, sprinkles, etc. until you get to the top of your jar.
- Thatās it! Add any optional sprinkles, etc. to the last layer and close up your jar and theyāre ready to serve, gifted, or stored!
Notes
- This recipe makes 5 to 6 twelve ounce jar cakes. The amount of jar cakes youāll get will depend on the cake recipe, the size of pan you bake it in, and the size of your jars. The recipe can easily be double and baked in two pans.Ā
- These are totally customizable and you can also use your favorite cake or frosting recipes. Typically a half batch of most cake recipes works perfectly for a 7 x 11 or 9 x 13 inch cake or jelly roll pan.Ā
- Iāve found wide mouth jars work best (like these) but you can make these in most mason jars.Ā
- Be sure to test the size of your cookie cutters to the size of the openings and if the jars taper. My mason jars tapered at the bottom so I had to use a smaller size for the bottom layer.Ā
- These jar cakes can last up to a day at room temperature (provided there are no perishable fillings such as fruit, whipped cream, etc.). Theyāll last 5-7 days in the fridge or can be frozen up to a month.

I Love these cake jars and to make some. What price would you charge for 1?
Also, about the confetti cake you used a homemade white cake, but when I tried that, and stirred in the sprinkles, it made my batter blue. Do you just stir once after you put in the sprinkles? Great ideas! I also want to check out your candy dipped strawberry recipe:)

Love this! I can’t wait to make these. What are the two chocolate frostings with the yellow cake? I’m going to send these to my daughter in a care package and she loves chocolate. š Thanks!
