For Chimichangas: Place 1 candy bar just below center of 1 tortilla. Fold bottom of tortilla up and over candy bar just until partially covered. Fold left and right sides of tortilla over; roll up, and place, seam side down, on a baking sheet. Repeat procedure with remaining candy bars and tortillas. Freeze 20 minutes.
Pour oil to depth of 1 inch into a large skillet; heat to 375°F Place 2 tortillas, seam sides down, in hot oil, gently pressing with tongs for a few seconds to seal. Fry tortillas 2 to 3 minutes on each side or until golden brown. Repeat procedure with remaining tortillas. Drain on paper towels. Serve with Raspberry Sauce and vanilla ice cream. Garnish, if desired.
For Raspberry Sauce: Combine first 3 ingredients and, if desired, orange liqueur, in a large saucepan. Bring to a boil; reduce heat, and simmer, uncovered, 5 minutes or just until raspberry mixture starts to thicken. Remove from heat, and let cool completely.
Press raspberry mixture through a wire-mesh strainer into a small saucepan, using the back of a spoon to squeeze out juice. Discard pulp and seeds. Whisk in 1 teaspoons cornstarch. Bring to a boil, and cook 1 to 2 minutes or until thickened. Store in refrigerator up to 3 days Makes 1 cup.
