Witches’ Brew Halloween Cake Jars Ingredients
• For the Cake
- Granulated Sugar – Provides sweetness and moisture to the cake; adjust levels to taste as desired.
- Butter – Adds richness and flavor; opt for unsalted butter for better control of the salt.
- Eggs – Essential for structure and moisture; substitute with flax eggs for a vegan option.
- Self-Raising Flour – Ensures the cake rises beautifully; use all-purpose flour combined with baking powder as a substitute.
- Cocoa Powder – Deepens the chocolate flavor; Dutch-processed cocoa offers a richer taste.
- Milk – Contributes moisture; replace with plant-based milk for a dairy-free treat.
- Vanilla Extract – Enriches flavor; almond extract can be an exciting twist.
• For the Buttercream
- Powdered Sugar – Creates a sweet and smooth buttercream frosting; no direct substitutions recommended.
- Food Coloring – Adds a spooky green hue to the frosting; use gel food coloring to maintain consistency.
• For Decoration
- Orange Fondant – Essential for crafting the witch legs; homemade modeling chocolate can serve as a substitute.
- Black Fondant – Perfect for detailing; black edible markers can also be used for simplicity.
- CMC Powder – Aids in hardening fondant; optional but recommended for sturdier legs.
Now that you have your ingredients ready, you’re just a whisk and a bake away from creating these whimsical Witches’ Brew Halloween Cake Jars!
Step‑by‑Step Instructions for Witches’ Brew Halloween Cake Jars
Step 1: Prepare Fondant Legs
Start by mixing CMC powder into orange fondant, kneading until well incorporated. Roll the fondant into thin strips to create witch legs, cutting them into desired lengths. Shape them and add black fondant stripes for detail. Keep the fondant covered to prevent it from drying out while you proceed with the next steps.
Step 2: Bake the Cake
Preheat your oven to 170°C (340°F). In a large mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy, about 3–5 minutes. Gradually add in the eggs, mixing well after each addition. Sift together the self-raising flour and cocoa powder, and slowly combine with the wet ingredients until just mixed. Pour the batter into a greased 9-inch square baking tin and bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
Step 3: Cool the Cake
Once the cake is baked, remove it from the oven and allow it to cool in the tin for 10 minutes. Carefully transfer the cake to a wire rack and let it cool completely. This cooling process is essential; frosting on a warm cake can melt and affect the layers in your Witches’ Brew Halloween Cake Jars.
Step 4: Make the Buttercream
While the cake is cooling, prepare the vibrant green buttercream frosting. In a mixing bowl, beat the unsalted butter until creamy and smooth. Gradually add powdered sugar, continuing to mix until fully combined. Stir in vanilla extract and gel food coloring until desired shade is achieved, ensuring it matches the theme of your Witches’ Brew Halloween Cake Jars.
Step 5: Assemble the Jars
With the cake cooled and buttercream ready, cut the chocolate cake into rounds that fit inside your jars. Layer the cake and buttercream in each jar, alternating between the two and adding festive sprinkles for a fun touch. Once you’ve created your delightful layers, insert the fondant witch legs into the top of each jar, positioning them to give a charming ‘peeking out’ effect, creating the allure of Witches’ Brew Halloween Cake Jars.
How to Store and Freeze Witches’ Brew Halloween Cake Jars
Room Temperature: Enjoy your cake jars fresh for 2-3 days at room temperature. Make sure they are covered to maintain moisture and prevent drying out.
Fridge: Store leftovers covered in the fridge for up to a week. This will help retain the freshness of the cake and buttercream, although the texture may soften slightly.
Freezer: For longer storage, freeze individual jars for up to 2 months. Ensure they are tightly sealed, either in airtight containers or with plastic wrap, to prevent freezer burn.
Reheating: If you prefer your cake jars warm, thaw them overnight in the fridge and microwave for a few seconds, but keep an eye on the fondant, as it may lose its shape when heated.

Expert Tips for Witches’ Brew Cake Jars
-
Perfect Cooling: Allow the cake to cool completely before frosting to prevent melting. Frosting a warm cake can create a gooey mess!
-
Vibrant Colors: To achieve that spooky green hue, use gel food coloring, which won’t alter the buttercream’s consistency like liquid coloring might.
-
Fondant Handling: Keep fondant covered while not in use; it dries out quickly. If working in humidity, use CMC powder in your fondant to prevent sagging.
-
Layering Technique: When assembling the layers in the jars, be gentle—but firm—so the cake pieces fit snugly without crushing the buttercream. This makes for a beautifully layered presentation.
-
Taste Variations: Feel free to customize your Witches’ Brew Halloween Cake Jars by trying different cake flavors or frostings, like cream cheese for a tangy twist!
-
Chilled Treats: For a refreshing experience, serve these jars chilled, perfect for Halloween parties or any festive gathering.
Witches’ Brew Halloween Cake Jars Recipe FAQs
What type of sugar should I use for the cake?
I recommend using granulated sugar as it provides the perfect sweetness and moisture to the Witches’ Brew Halloween Cake Jars. While it’s best to stick to the recipe, you can adjust the sugar levels to taste if you prefer a less sweet cake.
How should I store my cake jars to keep them fresh?
For optimal freshness, you can store your cake jars at room temperature for 2-3 days if they are covered. If you prefer to keep them longer, refrigerate them for up to a week. Just remember that refrigerating might soften the texture a bit, so for best results, enjoy them sooner rather than later!
Can I freeze the cake jars for later use?
Absolutely! To freeze your Witches’ Brew Halloween Cake Jars, ensure that each jar is tightly sealed—either with an airtight lid or plastic wrap—to prevent freezer burn. They can be frozen for up to 2 months. When it’s time to enjoy them, thaw them overnight in the fridge and consider warming them gently in the microwave for a few seconds if you’d like.
What should I do if my fondant legs start to sag or lose shape?
If you’re working in a humid environment, incorporate CMC powder into your fondant to help it maintain its shape and prevent sagging. Always keep the fondant covered when not in use to prevent it from drying out. If it does harden, you can gently knead a little shortening into it to restore some pliability before shaping.
Can these cake jars accommodate dietary restrictions?
Yes! You can adapt this recipe for various dietary needs. Substitute eggs with flax eggs for a vegan option, and use plant-based milk instead of regular milk. If anyone has allergies to gluten, you could experiment with gluten-free flour blends in the cake, though I can’t guarantee the same texture.
What if I can’t find orange fondant for the witch legs?
If orange fondant is hard to come by, don’t worry! You can make your own modeling chocolate at home as a substitute. It’s easy to make and gives a similar result while allowing you to customize colors just as you like.
