I find certain desserts synonymous with various events: fruit pies for summer picnics, decorated cakes for birthdays, just-made soufflés for a small dinner party - and Bundt cakes for a casual Sunday brunch. Just slice up the cake beforehand and set out on a pretty platter for the dessert line. This recipe makes a cake that is especially enticing with the rich tunnel of espresso and chocolate.
Tips for Making the Mocha Sour Cream Bundt Cake:
Prepare the Bundt Cake Pan:
- This is a simple Bundt cake to prepare, so not much can go wrong except when you unmold it. Spend a little extra time preparing your pan to lessen the chances of the cake not releasing properly. Generously spray the pan with baking spray making sure to get the spray into any little crevices.
Ingredients for the Sour Cream Coffee Bundt Cake:
- The star of this cake is the tunnel of sweet mocha goodness running around the center. Use a high-quality bittersweet chocolate chopped into bits or chocolate chips. Additionally, a finely ground espresso is best to boost up the coffee flavor.
- Bring the sour cream, butter and eggs to room temperature before starting the cake batter. This will ensure your batter does not 'break' because the emulsification process didn't work properly.
- Chop the butter into ¼" size pieces. This recipe does not use the creaming process where the sugars and butter are blended in the beginning of mixing. The butter for this cake will be added to the dry ingredients and combined.
- Combine the sour cream, eggs and egg yolks in a separate bowl as you want to add these two ingredients to the mixing bowl together.
Mixing and Assembling the Mocha Bundt Cake Batter
- Combine the dry ingredients - sugar, flour, baking powder and baking soda - in the bowl of a stand mixer (yes, you may use a hand mixer).
- Next add the softened butter and using the paddle attachment for your mixer, mix on the lowest speed for 2 - 3 minutes. Scrape down the sides of the bowl as needed. Mix for an additional minute if there are still large chunks of butter.
- Add half of the eggs/sour cream mixture to the bowl, mix on low speed for one minute, scrape the sides of the bowl, add the second half of the eggs/sour cream, mix on low speed until all ingredients are combined. The batter will be quite thick.
- Pour half of the batter into the prepared Bundt pan and smooth with a spatula making a small well in the center. Sprinkle the brown sugar/chocolate/expresso mix into the well and press down lightly with your fingers. Add the second half of the batter to the pan and smooth with a spatula. Your cake is now ready for the oven!
Unmolding the Bundt Cake:
- Place the cake pan on a cooling rack for 10 minutes after removing from the oven. After 10 minutes flip the pan upside down onto the cooling rack, use oven mitts as the pan is still hot, and allow to cool completely (approximately one hour).
- After the cake has cooled the pan should be carefully lifted off the cake. If the cake does not come out of the pan on its own, gently loosen the sides with a small spatula or blunt knife.
- Mix together the brewed expresso (or coffee) and confectioners' sugar and drizzle over the cake. Enjoy!
