A composite volcano is composed of many layers of ash and cooled lava flows resulting from sequences of explosive and non-explosive eruptions. The arrangement of these layers can be quite complex.
A stratovolcano is a conical volcano with a steep profile that is composed of many layers of hardened lava, pumice, tephra, and volcanic ash. Stratovolcanoes capable of producing both effusive and explosive eruptions, some of which can be very large. They are the most dangerous type of volcano.

A shield volcano forms from repeated eruptions of low-viscosity basaltic lava that flows easily and covers a large area. The lava builds up in layers, gradually creating a broad, gently-sloping volcano with a shield-like shape. These volcanoes are typically not very steep and have a large summit caldera or crater.

Mount Krakatoa is an island volcano in Indonesia. The volcano is a stratovolcano. This means that it is tall and cone shaped, with many layers that vary between lava, ash, and tephra. The sides of the volcano are very steep.

I guess that would depend on what size the volcano roll is, and what ingredients were used to make it.
Mount Cameroon is a stratovolcano, which is a conical volcano built up from many layers of hardened lava, tephra, pumice, and volcanic ash. It is one of the most active volcanoes in Africa.
