Orange-Raspberry Dreamsicle Cake

I haven't made this yet, but I am going to be making it next week. I can't remember where I found this recipe, somewhere online. If you have any suggestions, feel free to post about them. The cooking time is kind of deceiving, a majority of it is freeze time.

• Ready In: 9 hrs 10 mins
• Serves: 18
• Yields: 18 slices

Ingredients

• 2 (13 ounce) packages  coconut macaroons (we used Archway)
• 1 1⁄2 pints  raspberry sherbet
• 2  pints vanilla ice cream
• 3  pints  Orange sherbet
•  pretty iced  cookie (optional)

Directions

1. Line a 13 x 9 x 2-in. pan with foil, letting foil extend about 2 inches above pan at both ends. Lightly coat with nonstick spray.
2. Line bottom of the pan with macaroons; press to flatten and form a layer. Freeze 20 minutes, or until firm. Meanwhile, refrigerate raspberry sherbet and 1 pt vanilla ice cream to soften slightly.
3. Drop spoonfuls of softened sherbet and ice cream into crust, alternating flavors and packing them down as you go. Freeze 2 hours, or until firm.
4. Repeat with orange sherbet and remaining vanilla ice cream. Freeze 30 minutes to set, then swirl surface decoratively. Freeze 6 hours, or until hard, and serve, or wrap airtight and freeze up to 2 weeks.
5. To serve: Lift foil by ends onto cutting board; remove foil. Cut in 9 bars; cut bars in half diagonally to make wedges. Garnish with iced cookies.
6. Planning Tip: The cake can be made through Step 4 up to 2 weeks ahead.
