Step‑by‑Step Instructions for Witches' Brew Halloween Cake Jars
Step 1: Prepping the Oven and Tin
Begin by preheating your oven to 170 degrees Celsius. While the oven warms up, generously grease and flour a 9-inch square cake tin to ensure your Witches' Brew Halloween Cake bakes evenly and releases effortlessly later.
Step 2: Creaming the Butter and Sugar
In a large mixing bowl, combine 360 g of butter and 360 g of granulated sugar. Using an electric mixer, cream them together on medium speed for about 2 minutes until the mixture is light, fluffy, and paler in color—this will add a delightful texture to your cake.
Step 3: Adding the Eggs
Next, incorporate the eggs into your creamed butter mixture. Add them two at a time, beating well after each addition until fully combined. This process helps to create a rich batter that holds its shape and supports the cake’s structure.
Step 4: Mixing Dry Ingredients
In a separate bowl, whisk together the self-raising flour, unsweetened black cocoa powder, baking powder, and salt. Sift this dry mixture into the butter and sugar blend in three batches, alternating with the 90 ml of milk to create a smooth batter. Finally, fold in 2 teaspoons of vanilla extract for a hint of aromatic flavor.
Step 5: Baking the Cake
Pour the cake batter into your prepared tin and smooth the top with a spatula. Place it in the preheated oven, baking for 45 to 50 minutes. To check for doneness, insert a skewer into the center; it should come out clean when the cake is perfectly baked and ready.
Step 6: Cooling the Cake
Once baked, carefully remove the cake from the oven and allow it to cool in the tin for about 2 to 3 minutes. Then, flip it onto a wire rack to cool completely. This step is essential to ensure your Witches' Brew Halloween Cake maintains its structure for later assembly.
Step 7: Preparing the Buttercream
While the cake cools, prepare the buttercream frosting. In a mixing bowl, cream 400 g of softened salted butter until smooth. Gradually add 800 g of sifted powdered sugar, mixing until combined before beating with an electric mixer. Once smooth, fold in 1¼ teaspoons of vanilla extract and milk if needed for a fluffy texture.
Step 8: Crafting the Witches' Legs
For the whimsical legs, knead 1 tablespoon of CMC powder into 250 g of orange fondant until well mixed. Roll the fondant into long strips about 5mm in diameter, cutting them into 10 cm lengths to create 18 cute witches' legs that will add a playful touch to your jars.
Step 9: Adding Stripes to the Legs
To bring your witches' legs to life, roll out the black fondant into thin strips measuring 2-3mm in diameter. Attach these strips to the orange fondant legs using a damp brush, creating stylish, spooky stripes that are sure to catch the eye.
Step 10: Shaping the Shoes
Next, roll the black fondant into small balls and shape them into tiny shoes. Use a damp brush once again to adhere these shoes to the ends of your orange legs, enhancing the detailing of your adorable Witches' Brew Halloween Cake Jars.
Step 11: Layering the Cake
Once the cake is fully cooled, use a serrated knife to level it off, then slice the cake into two equal layers. Take a 3-inch round cutter to cut out 9 circles from each layer, giving you a total of 18 cake circles to fill your jars deliciously.
Step 12: Assembling the Jars
To assemble your Witches' Brew Halloween Cake Jars, start by placing a teaspoon of sprinkles at the bottom of each jar. Press in one cake circle, add a layer of buttercream, and sprinkle more on the sides. Repeat the layering with another cake circle and a swirl of buttercream on top.
Step 13: Finishing Touches
Finally, take a skewer to create small holes at the top of each layered jar. Insert your fondant witches' legs into the jars for a whimsical presentation. Your enchanting Witches' Brew Halloween Cake Jars are now ready to delight everyone!

Make Ahead Options
These Witches' Brew Halloween Cake Jars are an ideal option for busy home cooks looking to save time! You can prepare the cake layers and buttercream up to 3 days in advance. Simply bake the cake, cool it completely, and wrap it tightly in plastic wrap before refrigerating to maintain its moisture. For the buttercream, store it in an airtight container in the fridge; just re-whip it slightly before using to restore that silky smooth texture. Assemble the jars on the day you plan to serve them by layering the cake, buttercream, and sprinkles. This way, your cake jars will be just as delicious and delightful, ready to impress with minimal effort!
Tips for the Best Witches' Brew Halloween Cake Jars
Get the Right Texture: Use room temperature butter and eggs for your cake batter; this ensures a smooth, well-mixed consistency, preventing dense or dry cake.
Sifting is Key: Don’t skip sifting your dry ingredients! It prevents lumps and creates a lighter cake, ensuring that your Witches' Brew Halloween Cake Jars turn out fluffy.
Cool Completely: Allow the cake to cool completely before assembling the jars. This helps in keeping the layers intact and prevents the buttercream from melting.
Layer with Care: When filling the jars, press the cake circles gently and avoid overloading on frosting—balance is key to achieving those delightful layers!
Stay Creative: Feel free to customize your jars with different colors of food coloring or sprinkles. This adds an extra dose of enchantment to your Witches' Brew Halloween Cake Jars!
Storage Tips: If not serving immediately, store assembled jars in the fridge. But avoid adding the fondant legs until you’re ready to serve—this keeps them looking fresh!
How to Store and Freeze Witches' Brew Halloween Cake Jars
Fridge: Store assembled Witches' Brew Halloween Cake Jars in the refrigerator for up to 3 days. Make sure the jars are tightly sealed to maintain freshness.
Freezer: If you want to freeze the jars, do so without the fondant decorations. Place the sealed jars in the freezer for up to 2 months. Thaw in the fridge overnight before serving.
Airtight Container: For leftover cake circles or buttercream, place them in an airtight container. Refrigerate the cake for up to 3 days and the frosting for up to 1 week.
Reheating: If you enjoy your cake warm, gently heat individual jars in the microwave for 10-15 seconds, ensuring not to melt the buttercream.
