2.5 cups of buttermilk equals 20 fluid ounces (or approximately 20 oz by weight for most practical purposes). Whether you’re whipping up a batch of air fryer fried chicken or a fluffy pancake batter, knowing this conversion ensures your recipes turn out perfectly every time. At airfryerrecipe.co.uk, we understand the importance of precise measurements, especially when using an air fryer where consistency is key.
Using the right amount of buttermilk can make or break your air fryer recipes. Too little, and your batter might be too thick; too much, and it could become runny. For 2.5 cups of buttermilk, which is 20 ounces, you’ll achieve the ideal consistency for most recipes. This measurement is particularly crucial for air fryer baking, where even small deviations can affect texture and cooking time.
Many of our favourite air fryer recipes, from buttermilk biscuits to marinated chicken, rely on this precise ratio. The acidity in buttermilk also helps tenderise meats and activates baking soda, making it a versatile ingredient in both savoury and sweet dishes.

While 2.5 cups of buttermilk equals 20 fluid ounces, the weight in ounces can vary slightly depending on the buttermilk’s thickness.

To measure 2.5 cups (20 ounces) of buttermilk perfectly, use a clear liquid measuring cup placed on a level surface. Pour until the meniscus (the curve at the liquid’s surface) reaches the 20-ounce mark. For sticky buttermilk, lightly grease your measuring cup first to ensure all the liquid pours out cleanly.
This quantity of buttermilk is perfect for marinating a whole chicken before air frying, making a large batch of pancakes, or preparing enough batter for several servings of onion rings. The 20-ounce measurement also works well for many cake recipes adapted for air fryer use. At airfryerrecipe.co.uk, we’ve found this amount ideal for family-sized portions.
Buttermilk’s acidity helps create tender textures in air-fried foods while promoting beautiful browning.

If you don’t have buttermilk for your 20-ounce requirement, you can make a substitute by adding 1 tablespoon of lemon juice or vinegar to every cup of milk (2.5 tablespoons for 2.5 cups). Let it stand for 5 minutes before using. This works well in most air fryer recipes calling for buttermilk.
