Measuring 300g of Creamy Peanut Butter in the Kitchen

Because 1 US Customary Cup (236.6 mL) of creamy peanut butter weighs 258g when measured packed firmly into cup, 300 Grams (300g) translates to 1.16 US cups (1 cup + 2 tbsp + 1 ¾ tsp). By contrast, using the chunky peanut butter measure (250g/cup — a 8g per-cup shift), 300g occupies 1 cup + 3 tbsp + ½ tsp (1.20 cups).

Without a kitchen scale, measure 1 cup + 2 tbsp + 1 ¾ tsp (18.6 tablespoons total) using packed firmly into cup technique. Dense and sticky; pack firmly into a dry measuring cup with a rubber spatula to purge air pockets, or coat the cup in non-stick oil spray.

Frequently Asked Questions

How many cups is 300 grams of creamy peanut butter? ▾

300 grams of creamy peanut butter (packed firmly into cup, 258g per US cup) equals 1 cup + 2 tbsp + 1 ¾ tsp (1.16 US Customary Cups, 1.1 Metric 250 mL cups, or 18.6 tablespoons).

Why is chunky peanut butter slightly lighter per cup than creamy? ▾

Rough peanut pieces cannot pack together as seamlessly as homogeneous puree, leaving small gaps that reduce cup weight by ~8g.

Can natural peanut butter be swapped 1:1 for commercial creamy peanut butter? ▾

Yes by weight, but stir thoroughly to integrate separated oil, and consider cookies may spread slightly more due to lack of hydrogenated palm oil.
