  We prove the graded braided commutativity of the Hochschild cohomology of $A$
with trivial coefficients, where $A$ is a braided Hopf algebra in the category
of Yetter-Drinfeld modules over the group algebra of an abelian group, under
some finiteness conditions on a projective resolution of $A$ as $A$-bimodule.
This is a generalization of a result by Mastnak, Pevtsova, Schauenburg and
Witherspoon to a context which includes Nichols algebras such as the Jordan and
the super Jordan plane. We prove this result by constructing a
coduoid-up-to-homotopy structure on the aforementioned projective resolution in
the duoidal category of chain complexes of $A$-bimodules. We also prove that
the Hochschild complex of a braided bialgebra $A$ in an arbitrary braided
monoidal category is a cocommutative comonoid up to homotopy with the
deconcatenation product which induces the cup product in Hochschild cohomology.
