Witches’ Brew Halloween Cake Jars Ingredients
For the Cake
- Self-Raising Flour – Provides structure to the cake; substitute with all-purpose flour combined with baking powder if unavailable.
- Granulated Sugar – Sweetens the cake; brown sugar can be used for a deeper flavor.
- Butter (unsalted) – Adds richness and moisture; coconut oil may be used as a dairy-free option.
- Eggs – Binds the ingredients and helps with leavening; unsweetened applesauce can be a vegan substitute (1/4 cup per egg).
- Unsweetened Black Cocoa Powder – Intensifies chocolate flavor for a rich taste; Dutch-process cocoa can be an alternative.
- Baking Powder – Provides additional leavening; ensure it’s fresh for optimal rise.
- Salt – Enhances flavors; use sea salt or kosher salt interchangeably.

For the Buttercream
- Butter (for buttercream) – Creates a creamy frosting base; can be replaced with vegan butter.
- Powdered Sugar – Sweetens and stiffens the buttercream; use a low-carb sweetener for a diabetic-friendly option.

For Decoration

How to Make Witches’ Brew Halloween Cake Jars
-
Prepare Cake Tin: Preheat your oven to 170°C (340°F) and generously grease a 9-inch square cake tin to ensure easy removal after baking.
-
Make Cake Batter: Cream together unsalted butter and granulated sugar until light and fluffy. Add eggs one at a time, mixing well after each addition, and then alternate incorporating your sifted dry ingredients with milk until fully blended.
-
Bake Cake: Pour the batter evenly into the prepared tin and bake for 45-50 minutes. Check for doneness by inserting a toothpick—it should come out clean when the cake is ready.
-
Cool Cake: Once baked, allow the cake to cool in the tin for about 10 minutes. Then, gently transfer it to a wire rack to cool completely, ensuring it sets nicely.
-
Make Buttercream: In a mixing bowl, beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, and electric green food coloring until the buttercream is smooth and vibrant.
-
Cut Cake: Level off the cooled cake and use a round cutter to cut out 9 circles. These will form the delectable layers in your jars.
-
Assemble Cake Jars: Start with a layer of sprinkles at the bottom of each jar. Then, layer in the chocolate cake circles followed by a generous layer of buttercream. Repeat the process until all layers are stacked.

Witches’ Brew Halloween Cake Jars Recipe FAQs
What type of flour should I use for the cake?
I recommend using self-raising flour for its structure and rise. If you don’t have any on hand, you can substitute it with all-purpose flour mixed with 1 teaspoon of baking powder per cup. Just be sure to thoroughly mix the baking powder with the flour for even distribution!
How long can I store the assembled cake jars?
You can store your Witches’ Brew Halloween Cake Jars at room temperature for 2-3 days, but if you want them to last a bit longer, refrigerate them for up to a week. Just make sure they’re covered tightly to keep them fresh and moist!
Can I freeze these cake jars?
Absolutely! For freezing, it’s best to prepare the cake layers and buttercream separately. Individually wrap the unassembled layers in plastic wrap and place them in an airtight container. They can last up to 3 months in the freezer. When you’re ready to enjoy them, simply thaw the layers in the fridge overnight and then assemble your cake jars!
What should I do if my buttercream is too runny?
If your buttercream is runny, it may have too much liquid. Start by chilling it in the refrigerator for about 15-30 minutes to help thicken it up. Alternatively, you can gradually add more powdered sugar until you reach your desired consistency. Just keep mixing, and it will come together beautifully!
Are there any allergy-friendly substitutes I can use?
Definitely! For a dairy-free option, use coconut oil instead of butter and almond or oat milk in place of regular milk. If you’re looking to make the cake vegan, substitute eggs with unsweetened applesauce (1/4 cup per egg). Always check ingredient packaging to ensure they meet your specific dietary needs.
How can I decorate without using fondant?
If fondant isn’t your thing or you want a simpler option, you can use chocolate or candy melts to create decorative shapes. Melt the chocolate and pipe it onto parchment paper in your desired designs, then let it set. Edible gels and colorful sprinkles can also jazz up your Witches’ Brew Halloween Cake Jars without the fuss of fondant!
