Expert Tips
- There are a few easy ways to drizzle the cake with chocolate sauce. You can pour it from a spouted measuring cup, drizzle it with a spoon, or fill a pastry bag or sandwich bag with a corner snipped off.
- Use melted butter melted shortening or a a nonstick vegetable oil spray to grease your bundt pan.
- wait til right when you’re ready to bake to grease your pan. If you grease it then let it sit, the grease will start to slide down the pan as it sits.
- Handle the Heat has article called How to Prevent Bundt Cake from Sticking. They recommend sprinkling granulated sugar or almond flour in place of flour over the greased pan.
Recipe FAQs
There is no perfect substitute for buttermilk, but you can make a decent substitute at home. Measure one cup of milk. Take out one tablespoon of the milk and add one tablespoon of either lemon juice or white vinegar. Stir and let the mixture stand for around ten minutes.
When mixing sprinkles into batter, use the long and skinny sprinkles (also called jimmies). Using nonpareils (the tiny balls) in the cake batter isn’t recommended because they bleed their colors easily. I used rainbow sprinkles, but chocolate would a fun alternative since it’s a chocolate marble cake.
