Baking – Does using powdered sugar instead of granulated sugar make cookie dough drier

bakingcookiessugar

I was baking cookies last week using granulated sugar (white and brown) and they were great.

The recipe says to put all 3 sugars into the molten butter and to stir for a while. Yesterday I thought it would be easier to grind the sugars into powdered sugar and add it that way.

The cookies this time are drier and taste less like vanilla than before. Could that have something to do with the powdered sugar?

I hope the question is on point enough. Sorry for the metric units.

250 g     flour
2 g       baking powder
0,33 tsp. salt
170 g     butter, melted
110 g     brown sugar
50 g      white sugar
1 pck.    vanilla sugar
1 pck.    vanilla pudding powder
1         egg
1         egg yolk
200 g     chocolate chips

This answer touches on the problem:

Superfine sugar will dissolve too quickly and won't allow enough air to be incorporated.

Powdered or superfine sugar will still give you the same sweetness property as the granulated sugar. However, the step of creaming butter and (granulated) sugar is not just for mixing. It also incorporates some air into the fat; a well-creamed mixture will look "fluffy" and paler in color.

In creaming the butter and sugar together, you are using the sugar to aerate the butter and fill it with bubbles that can capture the gasses released by your leavener. The more fine bubbles you have in your network, the lighter in texture your cakes will be and the finer the crumb. This is true for your muffins as well, while it makes your cookies light and crisp instead of hard and dense. (King Arthur Flour blog)
