Witches’ Brew Halloween Cake Jars Ingredients
-
For the Cake
• Self-Raising Flour – Provides essential structure; you can substitute with all-purpose flour mixed with baking powder.
• Granulated Sugar – Sweetens the cake to perfection; consider coconut sugar for a unique flavor twist.
• Butter (unsalted) – Adds richness and moisture; margarine or vegan butter works for a dairy-free alternative.
• Eggs – Binds the ingredients and contributes to moisture; use flaxseed meal mixed with water for a vegan option.
• Unsweetened Black Cocoa Powder – Delivers a deep chocolate flavor; replace with regular cocoa powder if needed.
• Baking Powder – Helps the cake rise; ensure it’s fresh or substitute with baking soda, adjusting the amount.
• Salt – Balances the sweetness; omit if you’re using salted butter.
• Milk – Enhances moisture and flavor; almond milk serves as a great dairy-free swap.
• Vanilla Extract – Adds a lovely flavor depth; it’s optional, but highly recommended for the best taste. -
For the Buttercream
• Butter (for buttercream) – Ensures the frosting is rich and creamy; substitute with the same options as above.
• Powdered Sugar – Sweetens the buttercream and provides a smooth texture; no direct substitutes recommended.
• Food Coloring (Electric Green) – Colors the buttercream vibrantly; use gel food coloring for optimal results. -
For Decoration
• Orange Fondant – Perfect for sculpting adorable witches’ legs; you can either make it homemade or buy it pre-made.
• Black Fondant – Creates stylish stripes on the witch legs; the same sourcing options apply as with orange fondant.
• CMC Powder – Helps fondant retain shape and firmness; can be omitted, but results may vary.
• Sprinkles – Optional but adds sparkle and fun; choose your favorite Halloween-themed sprinkles to enhance the jars.
These Witches’ Brew Halloween Cake Jars are not just a treat for the taste buds; they’re also a feast for the eyes, making them the perfect addition to your Halloween celebration!
Step‑by‑Step Instructions for Witches’ Brew Halloween Cake Jars
Step 1: Prepare the Cake
Preheat your oven to 170°C (340°F) and grease a 9-inch square baking tin. In a large mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy, about 3-5 minutes. Gradually add eggs, mixing well after each addition. In a separate bowl, whisk together the self-raising flour, black cocoa powder, baking powder, and salt, then sift this mixture into the wet ingredients in batches, alternating with milk and vanilla. Pour the cake batter into the prepared tin and bake for 45-50 minutes, or until a skewer inserted in the center comes out clean. Allow the cake to cool completely.
Step 2: Make the Buttercream
While the cake is cooling, it’s time to whip up the vibrant buttercream. In a mixing bowl, beat the softened unsalted butter until creamy and smooth, which should take about 3 minutes. Gradually add in the powdered sugar, mixing until well incorporated and fluffy. Then, stir in the vanilla extract and electric green food coloring until you achieve your desired hue, ensuring the buttercream is evenly colored and has a rich, creamy texture.
Step 3: Prepare Fondant Decorations
Now we’ll create those adorable fondant witch legs that will make your Witches’ Brew Halloween Cake Jars truly special. Knead CMC powder into the orange fondant to help it hold its shape, then roll it out and cut into thin strips for the legs. Use black fondant to create shoes and make small stripes to attach to the orange pieces. Allow these fondant decorations to set while you assemble the cake jars, as this will help them maintain their form.
Step 4: Assemble the Cake Jars
Once your cake is completely cooled, cut it into 3-inch circles that will fit snugly in the jars. If desired, sprinkle a handful of Halloween-themed sprinkles at the bottom of each jar to add a festive touch. Alternate layers of chocolate cake and vibrant buttercream in each jar, gently pressing down to ensure stability. Finish with a generous swirl of buttercream on top to create a lovely peak.
Step 5: Final Touches
Now comes the fun part—adding the fondant witch legs! Take a skewer and insert it into the center of the buttercream swirl, then gently push the fondant legs into the skewer until they stand upright and appear to be emerging from the jars. Allow the Witches’ Brew Halloween Cake Jars to set as needed, or enjoy immediately for a spooktacular treat!

And, if you decide to use fondant, choose gel coloring for a vibrant green finish!
How should I store the Witches’ Brew Halloween Cake Jars?

What if my buttercream is too soft or too firm?
Very common! If your buttercream is too soft, it may be due to the butter being too warm. Try chilling it in the refrigerator for about 10-15 minutes, then whip it again until the desired consistency is achieved.
