Meanwhile, in a small pot off the heat, whisk together the maple sugar and cornstarch. Add the egg yolks and whisk to combine. Add the milk and whisk to combine. Bring to a boil over medium heat, whisking constantly and scraping the bottom and sides of the pot, until thickened. Remove from the heat and let cool. Strain the pastry cream through a sieve set over a bowl, if needed.
