| 1/8 cup (2 Tbsp) | 24 g | 0.85 oz |
| 1/4 cup (4 Tbsp) | 48 g | 1.69 oz |
| 1/3 cup (5⅓ Tbsp) | 64 g | 2.26 oz |
| 1/2 cup (8 Tbsp) | 96 g | 3.39 oz |
| 2/3 cup (10⅔ Tbsp) | 128 g | 4.52 oz |
| 3/4 cup (12 Tbsp) | 144 g | 5.08 oz |
| 1 US cup (16 Tbsp) | 192 g | 6.77 oz |
| 2 US cups (32 Tbsp) | 384 g | 13.55 oz |
How to Measure Baking Powder Correctly (Scoop vs. Scale)
Dip measuring spoon into tin, sweep flat against the built-in leveler rim. Never heap. 1 tsp = 4.0g; 1 Tbsp = 12.0g; 1 cup = 192g.
Double-acting leavener: too much baking powder creates massive gas bubbles that burst in the oven, collapsing the cake center and leaving a bitter chemical metallic aftertaste.
1-to-1 Substitute for Baking Powder: Baking Soda + Cream of Tartar
For 1 tsp (4g) baking powder: combine 1/4 tsp (1.3g) baking soda + 1/2 tsp (1.7g) cream of tartar + 1/4 tsp cornstarch.
Single-acting: reacts immediately upon hydration, so cakes must be baked without delay.
Storage, Shelf-Life & Humidity Impact on Baking Powder
Pantry Storage & Shelf-Life
Keep in airtight tin in a dry cupboard. Test freshness: stir 1/2 tsp into 1/4 cup warm water; it must fizz vigorously.
Estimated Shelf-Life: 6 to 12 months once opened.
Kitchen Humidity & Density Impact:
Ambient moisture neutralizes the internal acid-base balance inside the tin over time, killing leavening power.
