An easy vegan boxed cake mix hack using just a few ingredients.
Preheat your oven to 180°C (160°C for fan assisted ovens) and line two 7-inch cake tins. Using a smaller size of cake tin will help you get thicker slices.
In a large bowl, mix the cake mix and baking powder together then stir in the Coca Cola. Keep stirring until you have a smooth cake mix and there's no powder left in the bowl.
Split the mixture between the two cake tins and spread it out evenly.
Bake for around 25 minutes, or until a toothpick comes out clean. Set aside to cool for 10 minutes, remove them from the tins then leave them to cool completely.
Once the cakes are cool, sandwich them together with the Betty Crocker icing and add a little more on top.
Decorate with vegan chocolate chips or any other decorations if desired and enjoy!
