First, grab a 3-quart metal mixing bowl. Line it carefully with plastic wrap, making sure to leave about a 2-inch overhang all around the edges. Pop it in the freezer for about 10 minutes to chill.
While it's chilling, gently mash your 6 cups of strawberry ice cream until it's just soft enough to spread.
Using a rubber spatula, evenly coat the inside of your chilled, plastic-lined bowl with a generous, thick layer of the strawberry ice cream. Place the bowl back in the freezer for 2 hours to firm up.
After the strawberry layer is firm, repeat the process. Gently mash 5 cups of chocolate-chip ice cream until spreadable. Spread it evenly over the strawberry layer. Return to the freezer for another 2 hours.
Next, do the same with 4 cups of pistachio-almond ice cream. Mash it, spread it over the chocolate-chip layer, and freeze for another 2 hours.
For your last layer, gently mash and fill the remaining space in the bowl with 2 cups of Dutch chocolate ice cream.
Once all layers are in place, cover the top of the bowl completely with the plastic wrap overhang. Freeze the bombe until it's rock solid, which will take at least 8 hours, or preferably overnight.
When you're ready to serve this delightful treat, simply invert the frozen bombe onto a pretty serving plate.
Carefully remove the mixing bowl and peel away the plastic wrap.
Garnish your beautiful bombe by gently pressing white sprinkles all over its surface.
You can return it to the freezer for a few more minutes if needed, or slice and serve it immediately to your loved ones! Enjoy this indulgent, easy-to-make dessert!
