  We obtain asymptotic for the quantity $\int_0^1 \bigg|\sum_{n\le
X}\tau_k(n)e(n\alpha)\bigg|d\alpha$ where $\tau_k(n) = \sum_{d_1\dots d_k = n}
1$. This follows from a quick application of the circle method. Along the way,
we find minor arc bounds for the exponential sum with $\tau_k$, and asymptotics
for high moments of the Dirichlet kernel.
