In this talk we discuss the construction of a basis of master integrals for the family of the
$l$-loop equal-mass banana integrals, such that the differential equation is in an $\varepsilon$-factorised form.
As the $l$-loop banana integral is related to a Calabi-Yau $(l-1)$-fold,
this extends the examples where an $\varepsilon$-factorised form
has been found from Feynman integrals related to curves (of genus zero and one)
to Feynman integrals related to higher-dimensional varieties.
