A lemon pound cake with lemon glaze delivers a moist, buttery crumb infused with bright citrus flavor, topped with a shiny, tangy glaze. This classic dessert requires precise measurements for the traditional 1:1:1:1 ratio of butter, sugar, flour, and eggs. Accurate ingredient quantities prevent common issues like dense texture or uneven rising. Bakers often convert between volume units (cups, tablespoons) and weight (grams, ounces) for consistency, especially when scaling recipes or using international measurements.
Whether you're a home cook adapting a family recipe or a student practicing precision in culinary measurements, tools like unit converters ensure reliability across systems like US customary and metric.
Ingredients and Unit Considerations
Gather these ingredients for a standard 9x5-inch loaf pan (about 10 servings):
- Cake:1 cup (226g) unsalted butter, softened (convert 1 cup butter to grams via a reliable tool for exactness); 2 cups (400g) granulated sugar; 3 large eggs; 3 cups (375g) all-purpose flour; 1/2 teaspoon baking powder; 1/2 teaspoon salt; 1 cup (240ml) whole milk; 1/4 cup (60ml) fresh lemon juice; zest of 2 lemons.
- Glaze:1 cup (120g) powdered sugar; 2 tablespoons (30ml) fresh lemon juice; 1 tablespoon (15ml) lemon zest.
Key conversions for bakers:
| US Volume | Metric Weight/Volume |
|---|---|
| 1 cup flour | 125g (spooned and leveled) |
| 1 cup sugar | 200g |
| 1 cup milk | 240ml |
| 1 tablespoon lemon juice | 15ml |

Step-by-Step Instructions
- Preheat and Prep:Heat oven to 325°F (165°C). Grease and flour a 9x5-inch loaf pan. Accurate oven temperature prevents overbaking—convert Fahrenheit to Celsius if needed (325°F = 163°C exactly).
- Cream Butter and Sugar:Beat 1 cup butter and 2 cups sugar until light and fluffy, about 5 minutes. This incorporates air for tenderness.
- Add Eggs:Mix in eggs one at a time, ensuring each incorporates fully. Scrape bowl sides.
- Combine Dry Ingredients:Whisk 3 cups flour, baking powder, and salt. Alternately add dry mix and wet ingredients (milk + lemon juice) to batter, starting and ending with flour. Fold in zest. Avoid overmixing to maintain structure.
- Bake:Pour into pan. Bake 60-70 minutes or until a toothpick inserted in center comes out clean. Cool in pan 10 minutes, then transfer to wire rack.
- Make Glaze:Whisk powdered sugar, lemon juice, and zest until smooth. Drizzle over cooled cake. For thicker glaze, convert and add more sugar (e.g., 1/4 cup extra = 30g).
Practical Tips and Common Mistakes
Measurement Precision:Volume measures like cups can pack differently—1 cup flour might weigh 120-150g depending on sifting. Weighing ingredients yields better results; convert via cup-to-gram tools for adjustments.
Scaling Recipes:For a bundt pan, double the batter (6 cups flour = 750g). Test small batches first.

✨ Paraphrase NowCommon Pitfalls:
- Underbeating butter-sugar: Results in flat cake. Aim for pale, voluminous mix.
- Incorrect flour: Too much makes it dry—spoon into cup, don't scoop.
- Oven variations: Use an oven thermometer; convert temps accurately.
- Glaze too thin: Gradually add sugar while converting units.
In baking science, pound cake relies on equal weights for balance—butter provides fat, sugar tenderness, flour structure, eggs moisture. Lemon adds acidity, reacting with baking powder for lift. Precise units maintain this equilibrium across recipes.
Store cake airtight at room temperature up to 3 days or freeze unglazed up to 2 months. Perfect for brunches, teas, or gifting.
