How to Make Halloween Cake Jars

Step 1: Prepare the Cake
Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan or line with parchment paper. In a large bowl, mix 1 box of cake mix, 1 cup water, ⅓ cup vegetable oil, and 3 eggs until smooth. Pour into the pan and bake for 25–30 minutes, or until a toothpick comes out clean. Let cool completely.

Step 2: Make the Frosting
In a large bowl, beat 1 cup softened butter until creamy. Gradually add 3–4 cups powdered sugar, 2–3 tablespoons milk, and 1 teaspoon vanilla extract. Mix until smooth and fluffy. Divide the frosting into separate bowls and add food coloring for your desired Halloween colors.

Step 3: Assemble the Jars
Crumb the cooled cake into small pieces. Spoon a layer of cake into each jar (about 2–3 tablespoons), followed by a layer of colored frosting. Repeat layers until jars are full, leaving about ½ inch at the top for decoration. Finish with a swirl of frosting and top with candy eyes, gummy worms, sprinkles, or crushed cookies to create a spooky “witch’s brew” effect.

Step 4: Chill and Serve
Cover jars with lids and refrigerate for at least 1 hour before serving to let flavors meld. Serve chilled with a spoon and enjoy!

You Must Know

For perfect Witches’ Brew Halloween Cake Jars, let the cake cool completely before crumbling to avoid melting the frosting. Crumble into small, even pieces for consistent layers.

Perfecting the Cooking Process

Bake the cake at the correct temperature and let it cool fully for neat layers. Alternate cake and frosting evenly, using a spoon or small spatula to avoid gaps. Top with frosting and decorations immediately so candy sticks.

Chill jars at least an hour before serving to let flavors meld and layers set. Add crushed cookies or candy worms for a spooky touch. Following these simple steps ensures your jars are delicious, visually appealing, and perfect for Halloween fun.
