Tips Dark Chocolate Fudge Cake
- Use milk instead of water for a richer taste and softer crumb
- Add an extra egg or egg yolk for more structure and fudginess
- Substitute melted butter for oil to enhance flavor
- Stir in a spoonful of sour cream or Greek yogurt for extra moisture
- Mix in hot coffee instead of liquid to deepen the chocolate flavor (it won’t taste like coffee)
- Don’t overbake, pull it out when a few moist crumbs remain for that fudgy texture
- Let the cake cool completely before slicing to keep it from crumbling
- Use high-quality chocolate chips or chunks for pockets of melted chocolate throughout
- Use regular cake mixes, not with pudding in the mix
- Use a brownie mix that is without caramels, but ok with chocolate chips
