Brown sugar contains molasses which adds moisture and affects texture. For every 1.5 cups (12 ounces) of brown sugar, you could use 1.5 cups white sugar plus 1-2 tablespoons of molasses or honey.

Also ensure your sugar is evenly distributed in the recipe rather than concentrated in spots that might burn.” } }, { “@type”: “Question”, “name”: “How do I measure 1.5 cups of brown sugar without packing it down?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “If a recipe specifies unpacked brown sugar (rare for UK recipes), simply spoon the sugar lightly into the measuring cup without pressing down. However, most British recipes assume packed measurements, so 1.5 cups would still be about 12 ounces. When in doubt, weight measurements are always more accurate for air fryer baking.” } } ] }

1.5 cups of brown sugar equals approximately 12 ounces (340 grams) when packed. This measurement is crucial for air fryer baking, where precise quantities can make or break your recipe. Whether you're making cookies, cakes, or glazes, knowing this conversion ensures consistent results every time.
Understanding brown sugar measurements
Brown sugar behaves differently than white sugar when measured by volume. Because of its moist texture and tendency to clump, brown sugar must be packed firmly into measuring cups to get an accurate reading. This is why weight measurements (ounces or grams) are often more reliable for baking, especially in air fryer recipes where space is limited and precision matters.
At airfryerrecipe.co.uk, we recommend using kitchen scales for the most accurate measurements. If you don't have scales, the standard conversion is 1 cup of packed brown sugar = 8 ounces, making 1.5 cups equal to 12 ounces. This conversion works for both light and dark brown sugar varieties commonly used in UK baking.
Why accuracy matters in air fryer baking
Air fryers cook food differently than conventional ovens, with intense circulating heat that can magnify measurement errors. Too much sugar can cause burning or uneven cooking, while too little might leave your baked goods dry. That's why converting 1.5 cups of brown sugar to ounces (12 oz) properly is essential for air fryer success.
Converting between cups and ounces
For those who prefer metric measurements, 12 ounces converts to about 340 grams. This conversion is particularly useful when following European recipes or using digital scales that display grams. Many modern air fryer recipes, like those found on our recipes page, include both volume and weight measurements for convenience.
Remember that brown sugar density can vary slightly between brands. If you're making something sensitive like air fryer cookies or cakes, it's worth checking your specific brand's packaging for any weight variations. Most UK supermarkets sell brown sugar in 500g packs, so 1.5 cups (340g) uses about two-thirds of a standard package.
Tips for measuring brown sugar
To measure 1.5 cups (12 ounces) of brown sugar accurately without scales, use the spoon-and-level method: spoon the sugar into your measuring cup, then press down firmly with the back of a spoon until the cup is full and the sugar is compacted. Level off the top with a straight edge for perfect measurement every time.
Common uses for 1.5 cups of brown sugar
This quantity (12 ounces) is perfect for many air fryer desserts. It's enough sugar for a batch of 12 cookies, a small cake, or a glaze for air fryer doughnuts. The moisture in brown sugar helps create that perfect chewiness in baked goods that air fryers excel at producing with their rapid air circulation.
For savory dishes, 1.5 cups of brown sugar makes excellent glazes for air fryer ham or barbecue sauces. Check out our chicken recipes section for ideas on how to incorporate this measurement into delicious main courses. The sugar caramelizes beautifully in the air fryer's high heat environment.
Storing brown sugar properly
After measuring your 1.5 cups (12 ounces), store remaining brown sugar in an airtight container to prevent hardening. Some bakers add a slice of bread or a terra cotta brown sugar saver to maintain moisture. Proper storage ensures your next measurement will be just as accurate for all your air fryer creations.
Adjusting recipes for air fryer use
When converting traditional oven recipes to air fryer recipes, measurements become even more critical. The concentrated heat of an air fryer means that 1.5 cups (12 ounces) of brown sugar might behave differently than in conventional baking. Start with slightly less sugar and adjust to taste, as the caramelization happens faster in air fryers.
