Step‑by‑Step Instructions for Witches' Brew Halloween Cake Jars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 170°C (340°F). While the oven warms up, grab a 9-inch square cake tin and grease it thoroughly with butter or cooking spray, then dust with flour. This will ensure your cake comes out easily after baking!
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together 360 g of softened butter and 360 g of granulated sugar using an electric mixer. Beat the mixture on medium speed until it transforms into a light and fluffy consistency, which should take about 3 to 5 minutes. This step is crucial for a moist Witches' Brew Halloween Cake!
Step 3: Incorporate the Eggs
Carefully add 6 eggs to your creamed mixture, two at a time. Make sure to beat the mixture well after each addition until fully combined. You want a smooth texture without any lumps, which will enhance the overall richness of your cake.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the self-raising flour, baking powder, black cocoa powder, and salt. Gradually sift this dry mixture into the wet creamed mixture in three parts, alternating with 90 ml of milk. Gently fold it all together while adding the 2 teaspoons of vanilla extract until fully combined, avoiding overmixing.
Step 5: Bake the Cake
Pour the cake batter into the prepared tin and smooth the top with a spatula. Place it in the oven and bake for 45 to 50 minutes, or until a skewer inserted into the center comes out clean. The cake should look risen and have a slight crack on top, indicating it’s perfectly baked.
Step 6: Cool the Cake
Once baked, carefully remove the cake from the oven and let it cool in the tin for about 2 to 3 minutes. After that, gently transfer the cake to a wire rack to cool completely. This cooling process is vital for achieving the perfect texture for your Witches' Brew Halloween Cake Jars.
Step 7: Prepare the Buttercream
While the cake cools, start making your buttercream frosting. In a clean mixing bowl, cream 400 g of softened salted butter until it’s soft and fluffy. Gradually add the sifted powdered sugar, mixing on low speed to avoid a sugar cloud, then whip until it’s smooth and creamy.
Step 8: Color the Buttercream
Add 1¼ teaspoons of vanilla extract to the buttercream and mix until well combined. If the mixture feels too stiff, you can blend in 2 tablespoons of milk or cream for a smoother texture. To create a spooky look, drop in a few drops of electric green food coloring and blend until the color is uniform.
Step 9: Level and Cut the Cake
Once the cake has cooled completely, use a serrated knife to level its top. Then, cut the cake into two layers. Using a round cutter, carefully cut out 9 circles from each cake layer, which will form the delicious layers for your Witches' Brew Halloween Cake Jars.
Step 10: Assemble the Cake Jars
To assemble your jars, optionally sprinkle some fun sprinkles at the bottom of each jar. Layer a cake circle into the jar, followed by a generous swirl of buttercream. Next, add even more sprinkles for an extra festive touch, then top it all off with another cake layer and a delightful buttercream swirl.
Step 11: Decorate with Fondant
Using a skewer, gently create small holes at the top of the jars where you can insert your whimsical fondant witch legs. Make sure they are secure and standing tall for that perfect Halloween effect. With each jar brimming with sweet layers, your Witches' Brew Halloween Cake Jars are now ready to cast their spell at your next gathering!

Make Ahead Options
These Witches' Brew Halloween Cake Jars are perfect for meal prep and can save you valuable time during the busy Halloween season! You can bake the cake up to 3 days in advance. Simply cool it completely, wrap it tightly in plastic wrap, and store it in the refrigerator to retain its moisture. The buttercream can also be made ahead of time; just refrigerate it in an airtight container for up to 3 days. When you're ready to assemble, allow the cake and frosting to come to room temperature before cutting and layering. This way, your cake jars will be just as delicious and festive, ensuring a sweet surprise awaits your guests at your Halloween gathering!

Witches' Brew Halloween Cake Jars Recipe FAQs

Absolutely! For the best results, use fresh ingredients. When choosing eggs, look for ones with uncracked shells and a clean, intact bloom. For butter, I recommend checking the expiration date and using high-quality brands for a rich flavor. The self-raising flour should be fresh to ensure proper leavening.
How should I store my Witches' Brew Halloween Cake Jars?
For deliciously fresh cake jars, store them at room temperature for up to 2 days, covered in plastic wrap to lock in moisture. If you need to keep them longer, transfer to the fridge in an airtight container for up to 5 days to maintain their scrumptiousness—no one likes dry cake, right?

What if my buttercream is too stiff?
Very importantly, if your buttercream is a bit too stiff for spreading or piping, don’t worry! Just add one tablespoon of milk or cream at a time, mixing until you achieve a smoother consistency. This will help it spread beautifully on your cake layers without any hassle!
Are there any dietary considerations I should be aware of?
Absolutely! When preparing your Witches' Brew Halloween Cake Jars, keep allergies in mind. Ensure all guests are aware of the ingredients, especially if they have sensitivities to gluten (consider gluten-free flour) or dairy (substitute with dairy-free butter). Additionally, these jars are fun but should be enjoyed responsibly—especially by pets, as chocolate can be harmful to them.
