How to Make Pound Cake with Sour Cream

Pound cake is a dense, buttery classic dessert traditionally made with equal weights of butter, sugar, flour, and eggs—hence the name "pound." Adding sour cream creates a moister, tender crumb while maintaining structure. This recipe yields one 9x5-inch loaf, perfect for home bakers. Accurate measurements matter in baking; use HowToConvertUnits.com to switch between imperial and metric units seamlessly, like pounds to grams or cups to milliliters, ensuring precision across recipes.

Ingredients and Unit Breakdown

Key to success is measuring by weight where possible for consistency. Here's the list with dual units:

• 1 cup (225g or 8 oz) unsalted butter, softened
• 2 cups (400g or 1.8 lb) granulated sugar
• 3 large eggs (about 150g total)
• 1 cup (240g or 8.5 oz) sour cream, full-fat for best texture
• 1 tsp (5ml) vanilla extract
• 2 cups (250g or 0.55 lb) all-purpose flour
• ½ tsp baking soda
• ¼ tsp salt

Pro tip: Convert flour from cups to grams using the density factor (1 cup ≈ 125g sifted). For international bakers, switch 1 lb butter equivalent to 454g directly on the site.

Step-by-Step Instructions

1. Preheat oven:Set to 325°F (165°C). Grease and flour a 9x5-inch loaf pan. (Convert Fahrenheit to Celsius instantly if needed.)
2. Cream butter and sugar:Beat 1 cup butter and 2 cups sugar on medium speed for 5 minutes until pale and fluffy. This incorporates air for lift.
3. Add eggs one at a time:Mix in each egg fully before the next, scraping the bowl. Avoid overmixing to prevent toughness.
4. Incorporate sour cream and vanilla:Blend in 1 cup sour cream and vanilla until smooth. Sour cream's acidity reacts with baking soda for tenderness.
5. Combine dry ingredients:Whisk flour, baking soda, and salt. Fold into wet mixture gently in three additions. Do not overmix.
6. Bake:Pour batter into pan. Bake 60–70 minutes or until a toothpick inserted in center comes out clean. Cool in pan 10 minutes, then on rack.

Batter weighs about 1.5 kg (3.3 lb) total—scale up/down by converting proportionally.

Practical Tips and Common Mistakes

Why sour cream?It adds fat and moisture without thinning batter like buttermilk. For substitutions, convert yogurt (similar density) at 1:1 ratio.

Troubleshooting:

• Cracked top? Normal from sugar's hygroscopic nature; tent with foil if browning too fast.
• Sinking center? Check oven temp—use converter for precise °F to °C.
• Dry cake? Weigh flour accurately; 1 cup extra is 30g off, ruining texture.

Store wrapped at room temp up to 3 days or freeze slices (convert storage volumes if scaling). Ideal for tea time, potlucks, or as base for trifles.

In summary, making pound cake with sour cream delivers reliable results with minimal ingredients. Focus on room-temp items and weight measurements for pro-level bakes.
