Instructions
Prepare the Cake
- Preheat the oven to 350°F. Thoroughly grease and flour a 12-cup Bundt pan.
- In a large bowl, whisk together the flour, cocoa powder, granulated sugar, baking soda, baking powder, salt, and espresso powder, if using.
- In another bowl, whisk together the oil, eggs, sour cream, buttermilk, and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients. Add the hot coffee or hot water and whisk until the batter is smooth and fully combined.
- Pour the batter evenly into the prepared Bundt pan.
- Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean with only a few moist crumbs attached.
- Cool the cake in the pan for 2 hours.
- Carefully invert the cake onto a wire rack or serving plate. Cool completely, then refrigerate for 2 hours before frosting.
Prepare the Caramel Butter Frosting
- Melt the butter in a saucepan over medium heat.
- Add the brown sugar and milk, bring the mixture to a gentle boil. Stir constantly for about 1 minute, or until slightly thickened.
- Remove from the heat and pour the mixture into the bowl of a stand mixer. Allow it to cool slightly.
- Using the mixer on low speed, gradually beat in the confectioners’ sugar.
- Increase the speed to medium and beat until the frosting is smooth, scraping down the sides of the bowl as necessary.
- Spread the frosting over the cake while it is still warm, allowing it to drip naturally down the sides.
- If desired, sprinkle with toasted pecans, walnuts, flaky sea salt, or chocolate curls before the frosting sets.
- Allow the frosting to cool completely before slicing.
Jessica’s Notes
Best Served With
- Serve at room temperature for the best cake texture and a softer caramel frosting.
- Vanilla ice cream makes a particularly good accompaniment to the rich chocolate and caramel flavors.
- Fresh berries provide a bright contrast to the richness of the cake.
Prep Ahead
- Bake the cake one day ahead and refrigerate before frosting.
- The caramel frosting is best made just before pouring over the cake.
- The unfrosted cake can be wrapped tightly and kept at room temperature overnight.
Storage
- Cover tightly and refrigerate for up to 5 days.
- Bring slices to room temperature for 20–30 minutes before serving for the best texture.
Freezer-Friendly
- Freeze the unfrosted cake, tightly wrapped, for up to 3 months.
- Thaw overnight in the refrigerator and frost before serving.
- Leftover caramel frosting freezes well for up to 3 months. Cool completely and store in an airtight container.
- Thaw the frosting overnight in the refrigerator, then rewarm gently over low heat or in the microwave, stirring frequently.
- If needed, whisk in 1–2 teaspoons of evaporated milk or whole milk to restore a smooth, pourable consistency.
- Extra caramel frosting is delicious drizzled over brownies, cinnamon rolls, pound cake, apple cake, or banana bread, spooned over vanilla ice cream, or served as a dip for graham crackers and fresh apple slices.
Variations
- Sprinkle toasted pecans or walnuts over the caramel frosting.
- Use dark brown sugar instead of light brown sugar for a richer caramel flavor.
- Finish with a light sprinkle of flaky sea salt for a salted caramel twist.
- Add 1 teaspoon cinnamon to the batter for a subtle warm spice.
- Add mini chocolate chips to the batter for extra chocolate flavor.
