You have two objects, so you'll need two mocks. Setup your first mock to return the second one, and it should be straightforward from there.

var mockA = new Mock<InterfaceA>();
var mockB = new Mock<InterfaceB>();

mockA.Setup(i => i.CreateObjectOfInterfaceB()).Returns(mockB.Object);

// Do your test

mockA.Verify(i => i.CreateObjectOfInterfaceB(), Times.Once);
mockB.Verify(i => i.DoSth(), Times.Once);
