How to Make Witches Brew Halloween Cake Jars
Step 1: Preheat the Oven

Step 3: Bake the Cake
Pour the batter into your prepared baking pan. Bake in preheated oven for about 50 minutes or until a toothpick inserted in the center comes out clean. Once done, allow it to cool completely on a wire rack.
Step 4: Make the Buttercream
- In a separate bowl, beat together salted butter and powdered sugar until smooth.
- Mix in vanilla extract and add milk if needed to achieve desired consistency.
- Incorporate a few drops of electric green food coloring until you reach your preferred shade.
