How to Make Witches’ Brew Halloween Cake Jars
-
Prepare Fondant Legs: Begin by kneading CMC powder into your orange fondant. Roll it into long strips and cut to about 10 cm lengths for the legs, then use the black fondant to create whimsical stripes or details.
-
Bake the Cake: Preheat your oven to 350°F (170°C). In a mixing bowl, cream together butter and granulated sugar until light and fluffy. Gradually add eggs, then combine dry ingredients and alternate with milk. Pour the batter into a greased and floured 9-inch cake tin.
-
Cool the Cake: Bake for 45-50 minutes, or until a skewer inserted into the center comes out clean. Once baked, let the cake cool completely on a wire rack.
-
Make Buttercream: In a bowl, cream the unsalted butter until smooth. Gradually mix in powdered sugar, adding vanilla extract and green food coloring until you reach your desired shade and smoothness.
-
Assemble Cake Jars: Cut the cooled cake into 9 circles. Start layering in your jars by alternating layers of chocolate cake and green buttercream. Top each jar with festive Halloween sprinkles and any additional decorations you desire.
-
Finish with Fondant Legs: Gently insert the prepared fondant witch legs into the top of each cake jar, allowing them to peek out for added whimsy.

These cake jars are best enjoyed fresh, so store them in a cool, dry place. You can keep them at room temperature for 2-3 days; however, if you’d like to extend their life, they can be refrigerated for up to 1 week. Make sure they are tightly covered to maintain their deliciousness.

Very! To freeze your Witches’ Brew Halloween Cake Jars, wrap each jar securely in plastic wrap and then in aluminum foil for extra protection. This way, they can last up to 3 months in the freezer. When you’re ready to indulge, simply thaw them in the refrigerator overnight and enjoy!
What should I do if my fondant legs are bending or not holding their shape?

How can I ensure my sprinkles don’t bleed onto the buttercream?
To keep your Witches’ Brew Halloween Cake Jars looking their best, assemble them as close to serving time as possible. Consider using high-quality decorating sprinkles that are less likely to bleed and avoid using very moist toppings to maintain the vibrant green color of the buttercream.
