Step‑by‑Step Instructions for Witches’ Brew Halloween Cake Jars
Step 1: Preheat and Prepare
Begin by preheating your oven to 170°C (340°F). Take a 9-inch square cake tin and grease it thoroughly with butter, then dust with flour to prevent sticking. This ensures that your cake will come out easily and maintains its lovely shape, making it perfect for those enchanting Witches’ Brew Halloween Cake Jars.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together 200 grams of unsalted butter and 200 grams of granulated sugar until the mixture is light and fluffy—this should take about 3-5 minutes with a hand mixer. Next, add two large eggs, one at a time, ensuring each is fully incorporated before adding the next. The end result should be a creamy, smooth mixture that adds moisture to your cake.
Step 3: Mix Dry Ingredients
In a separate bowl, combine 300 grams of self-raising flour, 80 grams of unsweetened black cocoa powder, 1 teaspoon of baking powder, and a pinch of salt. Sift these dry ingredients together to aerate the flour and eliminate any lumps. Gradually add this mixture to the creamed butter and sugar, alternating with 200 milliliters of milk, and mix until just combined. This forms a rich, chocolaty cake batter for your Witches’ Brew Halloween Cake Jars.
Step 4: Bake the Cake
Pour your cake batter into the prepared tin and smooth the top with a spatula. Bake in the preheated oven for approximately 45 to 50 minutes or until a skewer inserted into the center comes out clean. The cake should spring back lightly when touched. Once done, remove from the oven and let it cool in the tin for about 10 minutes before transferring it to a wire rack to cool completely.
Step 5: Prepare the Buttercream
While the cake cools, make the vibrant green buttercream. In a mixing bowl, combine 250 grams of unsalted butter with 500 grams of powdered sugar using a hand mixer on low speed. Once combined, add 1 teaspoon of vanilla extract and a few drops of electric green food coloring. Beat on medium speed until the mixture is smooth and creamy, about 2-3 minutes. Set aside this delightful buttercream for layering in your jars.
Step 6: Cut the Cake
After your cake has completely cooled, use a serrated knife or cake leveler to cut it into nine 3-inch circles. This will be the perfect size for layering inside your Witches’ Brew Halloween Cake Jars. Ensure the edges are smooth, allowing each slice to fit snugly together with the buttercream and sprinkles.
Step 7: Assemble the Jars
Start layering your Witches’ Brew Halloween Cake Jars by placing one circle of chocolate cake at the bottom of each jar. Add a generous spoonful of the green buttercream, followed by a sprinkle of colorful decorations. Repeat this layering process—cake, buttercream, and sprinkles—until the jars are filled to the top, leaving a visual treat for all to see.
Step 8: Final Touches
To finish these charming Witches’ Brew Halloween Cake Jars, top each jar with a swirl of the remaining buttercream using a piping bag. Add a handful of sprinkles for a festive flair and then carefully position the fondant witches’ legs atop each jar for that iconic Halloween touch. Your delightful treats are now ready to enchant everyone at your spooky gathering!

Witches’ Brew Halloween Cake Jars Recipe FAQs
What type of flour should I use for the cake?
Absolutely! You can use self-raising flour for a light and fluffy cake. If you don’t have it, substitute with all-purpose flour and add 1 teaspoon of baking powder for every cup.
How should I store leftover cake jars?
You can store leftover Witches’ Brew Halloween Cake Jars at room temperature for up to 3 days. For longer freshness, refrigerate them for up to a week, ensuring they’re tightly covered with plastic wrap to keep the buttercream moist.
Can I freeze the cake jars?
Yes, indeed! If you’re planning to freeze your Witches’ Brew Halloween Cake Jars, first wrap each jar tightly in plastic wrap, then place them inside airtight containers. They can be frozen for up to 3 months. To enjoy, simply thaw them in the fridge overnight before serving.
How can I make the fondant witches’ legs?
Making fondant witches’ legs is fun and simple! Start with black and orange fondant. Roll out thin tubes for legs and make small sections for the feet. If you want them to hold their shape, consider using a bit of CMC powder mixed in, which helps the fondant set better. Allow them to dry for at least 24 hours before using them to decorate your cake jars.
Are there any dietary considerations for this recipe?
Certainly! If you’re making these jars for someone with egg allergies, you can substitute the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water = 1 egg). Also, use plant-based milk and margarine for a dairy-free option. Just make sure your fondant doesn’t contain any allergens like nuts, especially if sharing with little ones!
What if my cake doesn’t rise properly?
Very! If your cake doesn’t rise, there could be a couple of reasons. Ensure your baking powder is fresh; it should have a strong reaction when mixed with wet ingredients. Also, don’t overmix your batter after adding the dry ingredients; this can lead to dense cake. Lastly, always check your oven temperature with an oven thermometer for perfect baking results!
