Witches’ Brew Halloween Cake Jars Ingredients
For the Cake
- Granulated Sugar – Adds sweetness and helps create a tender cake texture.
- Butter – Enhances moisture; use unsalted for better salt control.
- Eggs – Essential for structure and moisture; consider flaxseed for a vegan twist.
- Unsweetened Black Cocoa Powder – Provides a rich chocolate flavor; swap with regular cocoa if needed, keeping in mind the color change.
- Self-Raising Flour – Gives structure and lightness; substitute with all-purpose flour mixed with baking powder if necessary.
- Milk – Adds moisture; non-dairy milk works well for a vegan option.
- Vanilla Extract – Elevates the flavor; stick with pure extract for maximum taste.
For the Buttercream
- Powdered Sugar – Crucial for the frosting texture; alternatives won’t give the same result.
- Green Food Coloring – Achieve that vibrant buttercream; gel food coloring is ideal for its intensity.
For Decoration
- Orange Fondant & Black Fondant – Used for the whimsical witch legs; other colors can work too if you’re feeling creative.
- Sprinkles – Sprinkle in the fun; any festive sprinkles will bright up your jars beautifully.
These Witches’ Brew Halloween Cake Jars are sure to be a showstopper at your next Halloween gathering!
Step‑by‑Step Instructions for Witches’ Brew Halloween Cake Jars
Step 1: Prepare Fondant Witches’ Legs
Begin by kneading CMC into the orange fondant until it’s pliable. Roll it into long strips and cut pieces for the length of the witch’s legs. Use black fondant to create stripes on the legs and tiny shoes at the bottom. Set these aside on a plate to harden, which should take about 30 minutes while you prepare the rest.
Step 2: Bake the Cake
Preheat your oven to 170°C (340°F) and grease a cake tin. In a large mixing bowl, cream together 1 cup of butter and 2 cups of granulated sugar until fluffy and light—about 3-5 minutes. Add in 4 eggs one at a time while mixing. Gradually combine the dry ingredients: 2 cups of self-raising flour mixed with ¾ cup of unsweetened black cocoa powder and alternate adding 1 cup of milk. Pour the batter into the prepared tin and bake for 45-50 minutes or until a toothpick inserted in the center comes out clean.
Step 3: Cool Cake
Once baked, remove the cake from the oven and allow it to cool in the tin for about 15 minutes. Transfer the cake to a wire rack to cool completely, which should take roughly another hour. Once cooled, slice the cake into 3-inch circles to perfectly fit into your jars.
Step 4: Make Buttercream
In a mixing bowl, beat 1 cup of unsalted butter until smooth and creamy, around 3-4 minutes. Gradually add 4 cups of powdered sugar while mixing on low to avoid a cloud of sugar dust. Add 1 teaspoon of vanilla extract and a few drops of green food coloring until you achieve a vibrant hue. Beat until fluffy for about 2-3 more minutes.
Step 5: Assemble Cake Jars
To assemble your Witches’ Brew Halloween Cake Jars, start by adding a spoonful of sprinkles at the bottom of each jar for a festive touch. Next, layer in the chocolate cake circles followed by a layer of green buttercream. Repeat the layers until the jars are filled, leaving some buttercream to pipe on top. Once filled, pipe the remaining buttercream and elegantly insert the fondant witch legs, making sure they’re peeking out.
Step 6: Store and Serve
These spooky treats are best enjoyed the same day they’re assembled to maintain the texture. However, they can be stored at room temperature for up to 2-3 days or refrigerated for about a week. Just remember, avoid stacking the jars to preserve the aesthetic of the Witches’ Brew Halloween Cake Jars!

Make Ahead Options
These Witches’ Brew Halloween Cake Jars are perfect for meal prep, allowing you to enjoy the festive fun with minimal last-minute effort! You can prepare the cake and buttercream up to 24 hours in advance. Bake the chocolate cake, cool it completely, and store the layers in an airtight container at room temperature, ensuring they retain their moisture. The buttercream can be made ahead as well; simply refrigerate it and bring it back to room temperature before use to maintain its creamy texture. When you’re ready to assemble, layer the cake circles with buttercream, finish with sprinkles, and top with the fondant witch legs. This way, you’ll have a delightful and visually stunning dessert with extra time to spare for your Halloween festivities!

Witches’ Brew Halloween Cake Jars Recipe FAQs
How do I choose the right ripeness of ingredients?
Absolutely! For the best results, use fresh eggs that have a firm shell and are not past their expiration date. Your butter should be at room temperature—soft but not melted—and for the milk, look for a clean, unexpired carton.
How should I store any leftover cake jars?
Very! These Witches’ Brew Halloween Cake Jars taste best when fresh, but you can keep them at room temperature for up to 2-3 days. If you want to extend their shelf life, refrigerate them for up to one week, ensuring they’re covered with clear wrap or in airtight containers to maintain texture.
Can I freeze the assembled cake jars?
Definitely! To freeze your Witches’ Brew Halloween Cake Jars, wrap them tightly in plastic wrap and then in foil to prevent freezer burn. They can be frozen for up to 3 months. When you’re ready to enjoy them, transfer to the fridge to thaw overnight or let them sit at room temperature for about 30 minutes when you’re ready to serve.
What can I do if my buttercream is too runny?
Oh, it happens! If your buttercream is too runny, this might be due to too much milk or insufficiently beating in the powdered sugar. To fix it, simply add more powdered sugar in small increments, mixing thoroughly until you reach the desired consistency. If it’s too thick, add a tiny splash of milk to loosen it slightly.
Are there any dietary considerations for this recipe?
Very important! This recipe contains allergens like eggs, gluten, and dairy. For a vegan alternative, you can replace the eggs with flaxseed meal (1 tablespoon flaxseed mixed with 2.5 tablespoons water equals one egg) and the milk with any non-dairy alternative. Always check your frostings and decorations for potential allergens if serving to others.
How can I prevent my sprinkles from bleeding?
Great question! Sprinkles can bleed if the cake jars are stored too long before serving. To minimize this, assemble your Witches’ Brew Halloween Cake Jars on the day of the event. If you must store them, keep sprinkles as a topping until just before serving to maintain their vibrant color.
