Step‑by‑Step Instructions for Witches’ Brew Halloween Cake Jars
Step 1: Prepare Fondant Legs
Knead CMC powder into the orange fondant until fully combined. Shape the fondant into long, thin strips, and cut them into appropriate leg lengths. For added visual interest, you can create black stripes with the black fondant. Set these aside to firm up as you continue with the recipe.
Step 2: Make Shoes
Take the black fondant and roll it into small shapes resembling shoes. Attach these tiny shoes to the orange fondant legs, ensuring they are securely connected. Allow the completed legs to rest overnight so they can harden properly, giving you stable decorations for your Witches’ Brew Halloween Cake Jars.
Step 3: Preheat Oven
Preheat your oven to 170°C (340°F) while you prepare your baking pan. Grease and flour a 9-inch square cake tin thoroughly to prevent the cake from sticking. Once the oven is up to temperature, you’ll be ready for the next steps.
Step 4: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to beat the softened unsalted butter and granulated sugar together until the mixture is light and fluffy, typically about 3-5 minutes. Gradually add the room temperature eggs, one at a time, mixing well after each addition to ensure a perfectly incorporated batter.
Step 5: Mix Dry Ingredients
In a separate bowl, whisk together the self-raising flour, unsweetened black cocoa powder, baking powder, and salt. This dry mixture will provide the structure and flavor to our chocolate cake. Once blended, you’re all set to combine the dry ingredients with the wet.
Step 6: Combine Ingredients
Alternately add the dry mixture and milk to the creamed butter mixture, starting and ending with the flour. Mix until the batter is smooth, making sure there are no dry flour pockets. This rich chocolate batter will be the base for your Witches’ Brew Halloween Cake Jars.
Step 7: Bake Cake
Pour the prepared batter into the greased cake tin, smoothing the top with a spatula for an even bake. Place it in the preheated oven and bake for 45-50 minutes. It’s done when a skewer inserted in the center comes out clean, signaling a beautifully moist chocolate cake.
Step 8: Cool Cake
Once baked, remove the cake from the oven and allow it to cool in the tin for 10 minutes. Carefully transfer the cake to a wire rack to cool completely. This step is crucial as frosting on a warm cake can lead to melting buttercream, which we want to avoid for our Witches’ Brew Halloween Cake Jars.
Step 9: Prepare Buttercream
In a clean mixing bowl, cream room temperature salted butter using an electric mixer until smooth. Gradually sift in the powdered sugar and mix until fully combined. Add vanilla extract and a touch of milk or cream to achieve the desired consistency, then tint the buttercream with electric green food coloring for that festive flair.
Step 10: Assemble Jars
Start layering your Witches’ Brew Halloween Cake Jars by cutting your cooled cake into small cubes. Spoon a layer of cake into the bottom of each jar, followed by a generous layer of green buttercream. Repeat the layers until you reach the top of the jars, and finish with a sprinkle of festive sprinkles and a fondant witch leg inserted into each jar for that perfect spooky touch.

Witches’ Brew Halloween Cake Jars Recipe FAQs
How do I know if my ingredients, like flour and sugar, are fresh?
Absolutely! To ensure the freshness of flour, look for any signs of bugs or unpleasant odors. Sugar typically stays fresh for a long time, but if it becomes hard or clumpy, it might be time to replace it. When using baking powder, check the expiration date and perform the “baking soda test”; mix a little with vinegar—if it fizzes, it’s still good!
What is the best way to store my Witches’ Brew Halloween Cake Jars?
You can enjoy your Witches’ Brew Halloween Cake Jars for 2-3 days at room temperature, stored in a cool, dry place. For longer storage, wrap them tightly and place them in the refrigerator where they will last up to a week. Always ensure they are properly sealed to keep the moisture in and prevent them from drying out.
Can I freeze the Witches’ Brew Halloween Cake Jars?
Yes, they freeze wonderfully! First, assemble your jars without the fondant decorations. Wrap each jar tightly in plastic wrap and then in aluminum foil to avoid freezer burn. They can last for up to 3 months in the freezer. When you’re ready to enjoy, simply transfer them to the refrigerator for about 6-8 hours to thaw before adding your whimsical fondant witch legs!
What should I do if my buttercream is too thin?
Very! If your buttercream turns out too thin, simply add more powdered sugar, one tablespoon at a time, mixing until you reach the desired consistency. If it’s too thick, you can beat in a bit of milk or cream to loosen it up. Remember, the butter should be at room temperature to achieve that fluffy texture!
Are there any dietary considerations for the Witches’ Brew Halloween Cake Jars?
Certainly! For those with gluten sensitivities, you can use a gluten-free flour blend instead of self-raising flour while ensuring the baking powder is gluten-free as well. Dairy-free options can be achieved by substituting unsalted butter with coconut oil or plant-based butter and using almond or oat milk. Always check your fondant and decorations for any allergens if you’re serving others, especially for kids!
Can I make variations to the recipe?
The more the merrier! Feel free to swap out the chocolate cake with a vanilla or sponge cake for a different flavor. Get creative with your buttercream colors for an extra festive flair! If you’re feeling adventurous, mix in seasonal sprinkles or edible glitter for even more fun—there’s no limit to how you can tailor these jars for your Halloween festivities.
