👩‍🍳 Step-by-Step Instructions

1. Prep:

• Preheat oven to 325°F (165°C). This lower temperature is key for even baking without doming or cracking.
• Grease and flour a 9×5-inch loaf pan or a 10-cup Bundt pan.

2. Make the Batter:

• In a large bowl, cream butter and sugar on medium-high speed for 5-7 minutes until very light and fluffy.
• Add eggs, one at a time, beating well after each. Add vanilla.
• In a separate bowl, whisk flour, baking powder, and salt.
• Alternate adding the dry ingredients and sour cream to the butter mixture, beginning and ending with flour. Mix until just combined—do not overmix.

3. Create the Chocolate Portion:

• In a small bowl, mix cocoa powder, hot water, and sugar into a smooth paste.
• Take one-third of the vanilla batter and stir it into the chocolate paste until uniform.

4. Marble the Batter:

• For Loaf Pan: Drop alternating large spoonfuls of vanilla and chocolate batter into the pan. Run a knife or skewer through the batter in a figure-8 pattern once or twice only—overmixing muddies the pattern.
• For Bundt Pan: Layer batters in rings, then swirl gently.

5. Bake:

• Bake for 60-75 minutes (loaf) or 55-65 minutes (Bundt), until a toothpick inserted into the center comes out clean.
• Let cool in pan for 20 minutes, then invert onto a wire rack to cool completely.

6. Optional Glaze:

• Chocolate Glaze: Melt ½ cup chocolate chips + 2 tbsp cream, drizzle over cooled cake.
• Vanilla Glaze: Mix 1 cup powdered sugar + 2 tbsp milk + ½ tsp vanilla.
