How to Make Witches’ Brew Halloween Cake Jars
-
Prepare Fondant Legs: Knead the CMC powder into the orange fondant until smooth, then roll it into long strips. Cut 10 cm lengths for 18 legs, and shape the black fondant for little shoes to complete your witch legs.
-
Bake Cake: Preheat your oven to 340°F (170°C). Begin by creaming the butter and sugar together until fluffy, then incorporate the eggs one by one. Gradually mix in the dry ingredients, alternating with the milk. Pour this delicious batter into a greased 9-inch square tin and bake for 45-50 minutes, or until a toothpick comes out clean.
-
Make Buttercream: In a mixing bowl, whip the softened butter until creamy, then gradually add the powdered sugar. Stir in the vanilla extract and mix in the green food coloring until it achieves your desired vibrant hue.
-
Cut Cake: Once the cake is cooled, level the top and cut it into 3-inch circles, perfect for layering in your jars. This will help create those delightful layers when assembling.
-
Assemble Jars: Start by adding a layer of sprinkles at the bottom of each jar, followed by a circle of cake, then a swirl of your bright buttercream. Repeat this process, ensuring you finish with a layer of buttercream topped with sprinkles and finally, insert your fondant witch legs for that spooky touch.
Optional: Add a drizzle of chocolate sauce between layers for an extra indulgent flavor!

Witches’ Brew Halloween Cake Jars Recipe FAQs
What type of flour should I use for the best results?
I recommend using self-raising flour for the best structure and lift in your Witches’ Brew Halloween Cake Jars. If you don’t have self-raising flour, you can easily substitute with all-purpose flour mixed with baking powder—use 1 teaspoon of baking powder for every cup of all-purpose flour to achieve similar results.
How should I store the assembled cake jars?
For optimal freshness, store your assembled Witches’ Brew Halloween Cake Jars at room temperature for up to 2-3 days. Make sure to cover them with a lid or plastic wrap to prevent drying out. If you need to keep them longer, refrigerate leftovers in an airtight container for up to a week.
Can I freeze the cake layers or buttercream?
Absolutely! You can freeze the unassembled cake layers and buttercream separately for up to 3 months. To freeze, wrap the cake layers tightly in plastic wrap and place them in a freezer bag. For the buttercream, store it in an airtight container. When you’re ready to assemble, just thaw everything in the fridge overnight for best results.
What if my buttercream is too runny?
If your buttercream is too runny, it probably needs more powdered sugar. Start by adding a couple of tablespoons at a time, mixing well until you achieve the desired consistency. If it’s too stiff, you can add a tiny bit of milk or cream to loosen it up. Remember to whip the mixture for a few more minutes to enhance the texture.
Can I make these cake jars vegan?
Yes, you can easily make these Witches’ Brew Halloween Cake Jars vegan! Simply substitute the eggs for flaxseed meal (1 tablespoon mixed with 2.5 tablespoons water for each egg) and replace the butter with margarine or dairy-free butter. For the milk, use almond or oat milk, and your festive treat will be perfectly plant-based!
How do I know when my cake is done baking?
To check if your cake is ready, simply insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, then it’s done! If there’s wet batter on the toothpick, continue baking and check every few minutes. Keep an eye on the cake’s surface; it should spring back slightly when touched.
