Method
- Preheat oven to 325°F (165°C). Grease and cocoa-dust a 9x5 inch loaf pan.
- Beat butter and sugar on medium-high for 4–5 minutes until pale and fluffy.
- Add eggs one at a time, beating well after each. Scrape down bowl as needed.
- Mix in sour cream and vanilla extract until smooth.
- Sift together flour, cocoa powder, baking powder, baking soda, and salt. Add to wet ingredients in three additions, mixing on low until just combined.
- Fold in melted, cooled dark chocolate.
- Pour into prepared pan. Bake 60–70 minutes until a toothpick comes out with just a few moist crumbs.
- Cool in pan 15 minutes, then turn out onto wire rack to cool completely.
- For glaze: melt chocolate chips, cream, butter, and corn syrup over low heat, stirring until smooth. Cool slightly, then pour over cake.
Notes
- Room temperature ingredients are essential for a smooth, even batter.
- Do not open the oven door before the 55-minute mark.
- This cake is even better on day two — bake ahead and glaze the day of serving.
- Substitute Greek yogurt 1:1 for sour cream if needed.
- Freeze unglazed slices individually for up to 3 months.
- Add ½ tsp espresso powder to the dry ingredients for a mocha variation.
