Step 1: Prepare the Baking Pan

Preheat your oven to 325°F (165°C).

Grease a 9×5-inch loaf pan or bundt pan thoroughly with butter or non-stick baking spray. Lightly dust with cocoa powder to prevent sticking and enhance the chocolate flavor.

Set aside while preparing the batter.

Step 2: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter until smooth and creamy.

Gradually add the granulated sugar and continue beating for approximately 4–5 minutes until the mixture becomes light and fluffy.

This process incorporates air into the batter and contributes to the cake’s tender texture.

Step 3: Add Eggs and Vanilla

Add the eggs one at a time, mixing well after each addition.

Once all eggs are incorporated, add the vanilla extract and mix until combined.

The batter should appear smooth and creamy.

Step 4: Mix Dry Ingredients

In a separate bowl, whisk together:

• All-purpose flour
• Cocoa powder
• Baking powder
• Baking soda
• Salt

Whisk thoroughly to ensure even distribution of ingredients.

Step 5: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the butter mixture, alternating with sour cream and milk.

Begin and end with the dry ingredients.

Mix on low speed until just combined.

Avoid overmixing, as this can make the pound cake dense and tough.

Fold in the chocolate chips gently using a spatula.

Step 6: Fill the Pan

Pour the batter into the prepared pan.

Smooth the top evenly using a spatula.

Tap the pan lightly on the countertop to remove any trapped air bubbles.

Step 7: Bake the Cake

Place the cake in the preheated oven.

Bake for approximately 65–75 minutes or until a toothpick inserted into the center comes out with only a few moist crumbs.

If the top begins browning too quickly, loosely cover with aluminum foil during the final baking period.

Step 8: Cool Completely

Remove the cake from the oven and allow it to cool in the pan for 15 minutes.

Carefully transfer to a wire rack and cool completely before frosting.

A fully cooled cake prevents the frosting from melting.

Step 9: Prepare the Chocolate Frosting

In a mixing bowl, beat the softened butter until creamy.

Add cocoa powder and mix thoroughly.

Gradually add powdered sugar, alternating with heavy cream.

Add vanilla extract and a pinch of salt.

Beat for 3–4 minutes until the frosting becomes smooth, fluffy, and spreadable.

Step 10: Frost the Cake

Once the cake is completely cool, spread the chocolate frosting generously over the top and sides.

Use an offset spatula to create decorative swirls if desired.

Finish with chocolate shavings or your favorite garnish.
