IME, the 2 Tbsp of dry PB2 mix up to be a little less than 2 Tbsp once you add the water.
Here, I just did some rough estimates for you (a little PB2 snack sounded good to me)
2 level Tbsp PB2 dry = 12 g (good, cause that's what the label says)
+ 1 Tbsp water = 25 grams total
I mixed that up and measured it out into level measuring spoons. That amount of PB2 filled 1 Tbsp + 1 and 1/4 tsp which is equal to about 1.4 Tbsp.
So, for every 2 Tbsp of dry PB2 you get about 1.4 Tbsp of 'wet' PB2. A fourth of a cup is 4 Tbsp. so if you do the math it comes out to about 5.7 Tbsp dry PB2 to equal about 1/4 of a cup wet PB2.
5.7 Tbsp is about 1/3 of a cup dry PB2 to mix up 1/4 of a cup wet.
Actual numbers YOU get may vary.
