I am thinking the same as Jade, Jeannie. Use healthier recipes for the cakes you enjoy. In the last six months I have drastically decreased the amount of chocolate and sugar I was eating. I now barely eat dairy and don't use it in my cooking and I never eat meat.
Early this year I bought a good quality blender and I now make my own almond milk. Every morning I whip up a smoothie for breakfast with some almond milk, a banana, dates, frozen berries, ice cubes and oats. When making cakes I normally use coconut oil instead of butter, dates and local unprocessed honey instead of sugar, almond meal or coconut flour instead of flour. I have also made my own chocolate using crushed almonds, dates, cacao powder and honey.
There are many healthy recipes and I found this on the Internet by typing in some of the ingredients I prefer to use. Sugar Free Carrot Cake
