🥚 3 Large Eggs Equals
🥚 Why Are 3 Eggs the Standard?
3 large eggs (150g) is the classic measurement in baking because:
- Perfect ratio: Matches 2 cups flour (250g) in classic cake formulas (3:5 egg-to-flour ratio)
- Ideal structure: Provides enough protein for structure without making baked goods rubbery
- Historical standard: Vintage recipes designed around half-dozen egg cartons (3 = half)
- Moisture balance: 150g eggs + 113g butter (1 stick) = perfect fat-liquid ratio
- Batch size: Makes 12 cupcakes, one 9" layer cake, or 6-cup Bundt - ideal family portions
- Easy scaling: Simple to halve (1.5 eggs) or double (6 eggs) with clear math

📏 Egg Size Matters: Weight Comparison
Not all eggs are created equal! Here's what 3 eggs weigh by size:
| Egg Size | Per Egg | 3 Eggs Total | When to Use |
|---|---|---|---|
| Small | 43g | 129g | Rarely sold; avoid for baking |
| Medium | 44g | 132g | UK standard; lighter results |
| Large (US Standard) ⭐ | 50g | 150g | Recipe default; use this! |
| Extra Large | 56g | 168g | Richer; may need less flour |
| Jumbo | 63g | 189g | Too much liquid; adjust recipe |
⚠️ Important: Recipe Assumption
Unless specified otherwise, all baking recipes assume LARGE eggs (50g each). Using different sizes can affect texture and structure!
🔬 3 Large Eggs: Whites vs Yolks Breakdown
🥚 Whole Eggs (3)
Best for:
- • All-purpose cakes
- • Cupcakes
- • Brownies
- • Custards
- • Quiche
🌕 Egg Yolks Only (3)
Best for:
- • Rich custards
- • Hollandaise sauce
- • Pastry cream
- • Ice cream base
- • Pound cake
⚪ Egg Whites Only (3)
Best for:
- • Meringue cookies
- • Angel food cake
- • Macarons
- • Royal icing
- • Pavlova
🧮 The Math
1 large egg (50g) contains:
- • Egg white: 30g (60%)
- • Egg yolk: 17g (34%)
- • Loss/membrane: 3g (6%)
3 large eggs (150g) contains:
- • Egg whites: 90g (60%)
- • Egg yolks: 51g (34%)
- • Loss/membrane: 9g (6%)
🔄 How to Substitute 3 Large Eggs
Using Different Egg Sizes
| If You Have: | Use This Instead: | Weight Match |
|---|---|---|
| Medium eggs | 3.5 medium eggs | 3 × 44g = 132g → add 1 tbsp beaten egg |
| Extra Large eggs | 2.5 extra large | 2.5 × 56g = 140g → close enough (10g less) |
| Jumbo eggs | 2 + 1 yolk | 2 × 63g + 17g = 143g → acceptable |
Using Egg Whites Only (Fat-Free)
Replace 3 whole eggs (150g) with:
- • 5 egg whites (150g) - Exact weight match, but drier texture
- • 4 egg whites (120g) + 2 tbsp oil - Better texture, adds back fat
- • 180ml liquid egg whites (carton) - Convenient but less structure
Note: Expect lighter color and slightly drier crumb. Good for angel food cake, meringues.

🌡️ Temperature & Handling Tips
🧊 Cold Eggs (Straight from Fridge)
Temperature: 40-45°F (4-7°C)
Best for:
- • Separating whites from yolks (easier when cold)
- • Whipping egg whites (more stable foam)
- • Making mayonnaise or aioli
🌡️ Room Temperature Eggs
Temperature: 65-70°F (18-21°C)
Best for:
- • Most baking recipes (cakes, cupcakes)
- • Creaming butter and eggs together
- • Mixing into batters smoothly
- • Even incorporation (no curdling)
⚠️ Why Room Temperature Matters
When 3 cold eggs (40°F) are added to room temp butter (65°F):
- ❌ Butter seizes and becomes grainy (fat solidifies)
- ❌ Batter looks curdled or separated
- ❌ Uneven mixing → dense spots in cake
- ✅ Room temp eggs blend smoothly → uniform batter → even crumb
🔧 Troubleshooting: Problems with 3-Egg Recipes
❌ My cake is dense and rubbery
Likely cause: Over-mixing after adding eggs, or too many eggs
Solutions:
- • Mix just until combined (overmixing develops gluten)
- • Verify you used 3 large eggs (not XL or jumbo)
- • Try using 2 eggs + 1 yolk instead (less protein)
- • Check oven temp (underbaking also causes rubberiness)
⚠️ My batter looks curdled/separated
Likely cause: Cold eggs added to room-temp butter
Solutions:
- • Prevention: Always use room-temp eggs (65-70°F)
- • Fix during mixing: Add 1-2 tbsp flour, mix briefly to re-emulsify
- • Or: Continue anyway - usually bakes fine despite appearance
- • Warm eggs quickly: 5-10 min in bowl of warm water
🔍 My cake is dry and crumbly
Likely cause: Not enough eggs, or eggs too small
Solutions:
- • Verify you used 3 large eggs (150g total)
- • If using medium eggs, add 1 extra white or 2 tbsp milk
- • Don't overbake (check 5 min early)
- • Try adding 1 extra yolk (keeps cake moist)
💡 Can I use 2 eggs instead of 3?
Yes, but with adjustments:
- For structure: 2 whole eggs + 1 white (120g total) - slightly drier but works
- For richness: 2 whole eggs + 1 yolk (117g total) - richer, denser
- Reduce other liquids: Decrease milk/water by 2-3 tablespoons
- Best use case: When you only have 2 eggs and can't get more!

👨🍳 Pro Baker Tips for Eggs
🥚 Freshness Test
Place egg in water: Sinks flat = fresh (best for poaching), Stands up = 2-3 weeks old (best for baking), Floats = discard.
⚖️ Weigh Your Eggs
Crack 3 eggs into bowl on scale. Should be 150g ±5g. If under, add beaten egg; if over, remove small amount.
🥣 Crack into Separate Bowl
Never crack directly into batter. One bad egg ruins everything! Always crack into small bowl first, then add to main bowl.
❄️ Storage Trick
Store eggs with pointed end down in carton (yolk stays centered). Use within 3-5 weeks of purchase for best baking results.
