Butter Sticks

From: Betty Crocker recipe card

Ingredients:
1/3 cup butter
2 cups Bisquick
1/2 cup cold water

Heat oven to 425. Melt in baking pan, 13x9 1/3 cup butter. Stir together Bisquick and water with fork in bowl to form a soft dough. Gently smooth dough into a ball on floured board. Knead 5 times. Roll dough into rectangle with rolling pin. Cut lengthwise in half. Cut each half crosswise into 12 strips, 3 inches long and about 3/4 inch wide. Dip each strip into the melted butter in the pan. Be sure both sides are covered.

Bake 12-15 minutes.

What I did differently from the recipe:
Nothing.

What I'll do differently next time:
???

Verdict:
Um... okay, it really hurts that the label of this recipe card said, "Recipes Children Can Make". What did I do wrong? My sticks were flat and crumbly, not puffy like the picture on the recipe card! If anyone makes this recipe I would love to know how yours turn out because this would be something I'd make all the time! Maybe I rolled my dough too much?
