Special equipment: a kitchen blowtorch
For the ice cream center: Spray a 4 1/2- to 5-quart metal bowl with nonstick spray and line with plastic wrap. Create a first layer using the softened cherry chocolate chip ice cream, then freeze for 30 minutes.
Add the softened mint chocolate chip ice cream for the second layer and freeze again for 30 minutes.
Add the softened chocolate chocolate chip ice cream for the third layer, then top with a layer of angel food cake. Cover in plastic wrap and freeze for at least 4 hours and up to 2 days.
For the meringue: Using a stand or electric hand-held mixer, whisk the egg whites until frothy. Add the cream of tartar and whisk again. With the machine running, add the sugar a little at a time and whisk until the meringue is glossy and forms stiff peaks.
Remove the ice cream bomb from the freezer and take off the plastic wrap on top. Turn out the frozen ice cream and cake onto a plate so that the cake layer is in contact with the plate and you have a dome.
Remove the plastic wrap from the dome and cover with the meringue, making peaks. Brown with a kitchen blowtorch and serve.
Propane gas torches are highly flammable and should be kept away from heat, open flame and prolonged exposure to sunlight. They should be used only in well-ventilated areas. Follow torch manufacturer's instructions for use.
