Melt chocolate chips in the microwave. Start with 30 seconds, stir and then microwave another 30 seconds. Repeat until chips are melted (shouldn’t take more than a minute to minute and half). Add softened cream cheese to the chocolate chips and beat with an electric mixer until smooth. Add 1 package (16 oz) powdered sugar and mix until well blended.
Turn truffle mixture into baking dish and press into a square. Cover with more plastic wrap and place in the refrigerator to chill up to one hour.
Remove mixture from refrigerator, cut into squares (I cut into 48 small squares) and roll into balls. Coat with cocoa powder, powdered sugar, or sprinkles. Store in refrigerator and take out at least 10 minutes prior to serving.
