Step‑by‑Step Instructions for Witches' Brew Halloween Cake Jars
Step 1: Preheat and Prepare
Preheat your oven to 170°C (340°F). While the oven heats up, prepare a 9-inch square cake tin by greasing it with butter and dusting it with flour. This will ensure your chocolate cake comes out smoothly after baking, leaving you with a perfect base for your Witches' Brew Halloween Cake Jars.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together the butter and granulated sugar using an electric mixer on medium speed until the mixture is light and fluffy, approximately 3-5 minutes. This step is crucial for incorporating air into the mixture, which will create a moist cake. Once fluffy, add the eggs two at a time, mixing until well combined after each addition.
Step 3: Mix the Dry Ingredients
In a separate bowl, combine the self-raising flour, unsweetened black cocoa powder, baking powder, and salt. Sift these dry ingredients together to remove any lumps and ensure an even distribution of the cocoa. Gradually add the dry mixture to the creamed butter and sugar, alternating with milk, and fold in the vanilla extract until just combined for your cake batter.
Step 4: Bake the Cake
Pour the cake batter into the prepared tin, spreading it evenly with a spatula. Gently tap the tin on the counter to release any air bubbles. Bake in the preheated oven for 45-50 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the tin for about 10 minutes before transferring it to a wire rack to cool completely.
Step 5: Slice the Cake Layers
Once the chocolate cake has completely cooled, carefully slice it horizontally into two even layers using a serrated knife. For a fun presentation in the Witches' Brew Halloween Cake Jars, cut 9 circles from each layer using a round cutter. These circles will be the delightful cake layers inside your jars.
Step 6: Prepare the Buttercream
In a mixing bowl, beat the softened butter with an electric mixer until creamy and smooth. Gradually add in the powdered sugar, mixing well after each addition until fully incorporated to create a fluffy buttercream. Add a few drops of green food coloring until you reach your desired shade for the festive buttercream that will layer delightfully in the cake jars.
Step 7: Assemble the Cake Jars
To assemble your Witches' Brew Halloween Cake Jars, start by sprinkling a layer of colorful sprinkles at the bottom of each jar. Next, add a layer of the chocolate cake circles followed by a layer of the green buttercream. Repeat layering until the jars are filled, leaving some space for frosting on top to create a stunning presentation.
Step 8: Decorate and Finish
Finally, pipe additional buttercream on top of each jar and add a sprinkle of festive sprinkles for that perfect Halloween touch. To complete the look, carefully insert pre-made fondant witch legs into the buttercream. Your Witches' Brew Halloween Cake Jars are now ready to enchant and delight your guests at any spooky celebration!
Make Ahead Options
These Witches' Brew Halloween Cake Jars are perfect for busy home cooks looking to save time during the spooky season! You can prepare the chocolate cake and buttercream up to 3 days in advance. Simply bake the cake, allow it to cool completely, and store it in an airtight container at room temperature to keep it moist. Make the buttercream and refrigerate it until ready to assemble. For the fondant decorations, create them 24 hours ahead of time, allowing them to harden. When you're ready to serve, layer the cake and buttercream in the jars, decorate with sprinkles, and insert the fondant witch legs for a quick, delicious, and visually stunning treat that will impress your guests!
Helpful Tricks for Witches' Brew Cake Jars
- Cool Properly: Allow the cake to cool completely before frosting. If it's still warm, the buttercream will melt, ruining the presentation.
- Prep Fondant Early: Make your fondant decorations in advance. This allows them to harden and hold their shape, ensuring a polished final look for your Witches' Brew Halloween Cake Jars.
- Layer Wisely: When assembling, ensure even layers of cake and buttercream for a perfect bite every time. This also helps maintain the jar's visual appeal.
- Use Quality Ingredients: Fresh ingredients make a big difference in flavor and texture, especially with chocolate cake. Invest in good quality cocoa powder for the richest taste.
- Customize Colors: Feel free to swap in your favorite colors for the icing and fondant! Just remember to stick to Halloween themes for that playful yet spooky vibe.

Witches' Brew Halloween Cake Jars Recipe FAQs
What is the best way to choose ripe ingredients for this recipe?
Absolutely! For the best results, look for fresh eggs that have no cracks and feel heavy for their size. Ensure your butter is at room temperature for easy creaming; it should be soft but not melted. When selecting cocoa powder, opt for a high-quality brand to ensure a rich flavor in your cake.
How should I store Witches' Brew Halloween Cake Jars?
You can store your cake jars at room temperature for 2-3 days, as long as they're kept in a cool, dry place. If you're looking to maintain freshness longer, refrigerate them in an airtight container, where they’ll last up to a week. I've found it's best to assemble them on the day they're served if you want to retain that delightful texture!
Can Witches' Brew Halloween Cake Jars be frozen?
Yes! These delicious cake jars can be frozen for up to a month. To do this, wrap each jar tightly in plastic wrap and place them in a freezer-safe container to prevent freezer burn. When you’re ready to enjoy them, just thaw them in the fridge overnight and serve cold. If you prefer, you can warm them slightly in the microwave for about 10 seconds to soften the buttercream.
What common issues should I be aware of while making these cake jars?
One common issue is using warm cake when applying the buttercream, which can lead to melting. To avoid this, ensure your cake is completely cooled before assembly. If your buttercream seems too soft, you can place it in the fridge for a short time to firm it up before applying it to the jars. Another tip is to make sure your fondant decorations are made a day in advance, allowing them ample time to harden.
Are there any dietary considerations for the Witches' Brew Halloween Cake Jars?
Yes, if you have guests with allergies or dietary restrictions, you can easily make swaps! Use dairy-free butter and almond milk for those avoiding dairy, and replace eggs with flax eggs (1 tablespoon ground flaxseed + 2.5 tablespoons water = 1 egg) for a vegan alternative. Always double-check with your guests about specific allergens regarding ingredients like cocoa, sugar, or sprinkles!
Can I adapt the recipe for different flavors?
Very much! You can switch the chocolate cake for a vanilla or even a pumpkin spice cake to create lovely variations. Additionally, feel free to customize your buttercream colors and flavors using different extracts like almond or peppermint to suit your festive theme. The more the merrier when it comes to creativity in the kitchen!
