Step-by-Step Instructions
1. Prepare Your Pan
- Preheat your oven to 350°F (175°C).
- Grease a 9×5-inch loaf pan and line it with parchment paper for easy removal.
2. Mix Dry Ingredients

- Mix in vanilla extract.
4. Incorporate Sour Cream and Dry Ingredients
- Alternate adding dry ingredients and sour cream to the butter mixture, starting and ending with the dry ingredients.

- Stir in milk to achieve a smooth batter.
- Optional: Fold in chocolate chips for an extra chocolatey surprise.
5. Bake the Cake

- Transfer the cake to a wire rack to cool completely.
6. Optional Chocolate Ganache

Tips for the Perfect Sour Cream Chocolate Loaf Cake
- Room Temperature Ingredients: Make sure eggs, butter, and sour cream are at room temperature for a smooth batter.
- Do Not Overmix: Overmixing can make the cake dense. Mix until ingredients are just combined.
- Check for Doneness: Every oven is different. Start checking at 50 minutes to avoid overbaking.
- Enhance Flavor: Add ½ tsp espresso powder to the batter to intensify the chocolate taste without making it taste like coffee.
- Storage: Keep the cake in an airtight container at room temperature for 3 days or in the fridge for up to a week.
