What Is Cake in a Jar?

Cake in a jar is a small dessert served in a jar. Some jar cakes are baked directly in oven-safe jars. Others are made by baking cake or cupcakes first, then layering cake pieces with frosting, filling, fruit, sprinkles, or candy inside the jar.

Jar cakes are easy to personalize because each child can choose a flavor, frosting color, and topping. They also make cute gifts when the jars are cooled, decorated, and tied with a ribbon.

Any favorite cake and frosting combination can be used for jar desserts. Try one of these ideas:

How to Bake Cake in a Jar

You can use a favorite cake recipe or cake mix for jar cakes. Fill each jar only about halfway so the cake has room to rise.

Basic Jar Cake Steps

  1. Prepare your cake batter.
  2. Grease the inside of each oven-safe jar.
  3. Place the jars on a cookie sheet.
  4. Fill each jar about halfway with batter.
  5. Bake at 350 degrees F for about 10 to 15 minutes, or until a toothpick inserted in the center comes out clean.
  6. Allow the jars to cool completely.
  7. Poke a small hole in the center of each cake if you want frosting or glaze to drizzle inside.
  8. Thin frosting with a small amount of milk or water, if needed.
  9. Drizzle frosting into the center and around the top.
  10. Decorate with frosting swirls, sprinkles, fruit, or a ribbon around the jar.

You can leave the cake with a simple drizzle, or decorate the top like a cupcake with buttercream frosting. Try a swirl with a star tip, colorful sprinkles, fruit, candy, or a small edible decoration.

Layered Cupcake Jar Cakes

Another easy method is to bake cupcakes separately, cut them in half, and layer the cupcake pieces inside a jar with frosting. This method is especially helpful when you do not want to bake directly in glass jars.

Layered Jar Cake Steps

  1. Bake cupcakes and let them cool completely.
  2. Cut each cupcake in half horizontally.
  3. Place one cupcake half in the bottom of a jar.
  4. Add a layer of frosting or filling.
  5. Add another cupcake half.
  6. Repeat layers until the jar is filled.
  7. Decorate the top with frosting, sprinkles, fruit, or candy.

Cake in a Jar Decorating Ideas

Jar cakes are fun because the decorating happens both inside and outside the jar. Kids can see the layers through the glass and add toppings to the top.

Easy Jar Cake Decorations

  • Pipe frosting swirls on top.
  • Add sprinkles, mini candies, or chocolate chips.
  • Layer cake and frosting in different colors.
  • Add chopped strawberries, raspberries, or other fruit.
  • Tie a ribbon around the cooled jar.
  • Add a spoon and gift tag for a homemade treat.
