Has anyone ever tried to substitute white sugar for light brown? and so how is the texture and flavor affected? Thanks in Advance! Here is the recipe

(BAKE 360) Chocolate Cut-Out Cookies
{modified from Cookie Craft}

2 & 1/2 c. all-purpose, unbleached flour
1/2 c. dutch-process cocoa (natural is OK, too)
1 tsp instant espresso powder
1/2 tsp. coarse salt
1 c. unsalted butter
1 c. sugar
1 egg
1 tsp. vanilla

Preheat oven to 350. Line baking sheets with parchment paper.

Whisk together the flour,cocoa, espresso powder and salt; set aside.

Cream together the butter and sugar until light an fluffy. Beat in the egg and vanilla until well combined.

In 3 additions, add the flour mixture at low speed. Scrape down sides and bottom of bowl as needed.

Roll the dough on a lightly floured and cocoa-ed surface. (I mixed the 2 of these, then spread on my rolling surface, on my rolling pin, and used it to dip my cookie cutters.)

Cut the cookies with a square cutter, then divide into smaller squares, if necessary, using a bench scraper.

Freeze cut cookies five minutes.

Bake 8 minutes. Let cool completely.
