Sugar Cookie Truffles

From Pillsbury's website. I'm trying a simple modification by using a package of sugar cookies rather than the steps of baking fresh, and halving the other ingredients. 30 cookies ought to be enough; hope I'm wrong! :-)

• Ready In: 50 mins
• Serves: 60
• Yields: 1 cookies

Ingredients

• 1 (17 1/2ounce) package  sugar cookie mix
• 1 (8 ounce) package cream cheese, softened
• 2 (12 ounce) packages white chocolate chips, divided
• 1⁄4 cup vegetable shortening, divided
•  decorator  candy sprinkles, sanding sugar or   nonpareils
• 1⁄2 cup butter, softened
• 1  egg

Directions

1. PREPARE cookie mix according to package directions to make 36 cookies, baking until edges are golden brown. Cool completely.
2. PROCESS all cookies, one dozen at a time, in food processer until fine crumbs. Beat cream cheese in large bowl with electric mixer until fluffy. Add crumbs to cream cheese. Mix on medium speed until evenly blended.
3. ROLL mixture into 60 (1-inch) balls. Cover and chill at least 1 hour.
4. MICROWAVE 1 package baking chips and 2 tablespoons shortening in medium microwave-safe bowl on HIGH 1 minute or until melted and smooth when stirred. Hold 1 truffle on fork over bowl. Spoon white chocolate mixture over truffle to coat, tapping fork gently until excess coating drips back into bowl. Push truffle off fork onto wax paper using a toothpick. Immediately garnish top of truffle with decorator sprinkles. Repeat to coat remaining truffles. If coating thickens, microwave 10 to 15 seconds. Prepare additional coating using remaining white chips and shortening when needed. Chill truffles until ready to serve.
