This cake is a combination of vanilla and chocolate batters that are swirled together. First, you need to preheat the oven to 350F. You will need a loaf bread pan and butter it with melted butter using a pastry brush (adds a little more buttery flavor to the cake) or just spray it with non-stick spray. Take a little piece of parchment paper and line it at the bottom of the pan. Has a saucepan of simmering water (the water should not be too hot). In a heatproof stainless steel bowl add semi-sweet or bittersweet chocolate, add coffee which is freshly brewed, or use water instead. Melt them together.

Remove them from heat and let them cool at room temperature. In your electric mixer, or with a hand mixer, beat the butter (at room temperature) until it is nice and smooth. Add sugar for about 3 minutes until it is light and fluffy. Add in eggs and vanilla extract for flavor, one at a time, until well combined. Scrape down the sides of the bowl as needed. In a separate bowl, whisk or sift the cake flour (gives the marble bread low gluten really nice soft tender crumb), use (all-purpose flour for substitute) with the baking powder and salt (leave out if you used salted butter).

With the mixer on low speed, alternately add the flour mixture (in three addition) and sour cream (in two additions), beginning and ending with the flour. Spoon a little less than half of the batter into a separate bowl and then stir in the melted chocolate. With two spoons, place a spoonful of the two batters alternately into your loaf pan (chocolate, white, chocolate, etc.). Run (don’t stir) a wooden skewer or toothpick through the two batters to achieve a marbled effect.

Bake in preheated oven for about 50 – 60 minutes or until a toothpick inserted into the center just comes out clean. Remove from oven and place on a wire rack to cool for 10 minutes before removing from pan. Cool completely. To remove it from the pan using a spatula or knife to make sure it is not sticking. Store in a covered container at room temperature. It can also be frozen.
