Directions

1. Using a hand beater with a whisk attachment, beat the egg yolks and 1/4 cup of the sugar in a large bowl on medium-high speed until it forms thick ribbons, 3 to 5 minutes. Add the mascarpone and vanilla and continue to whisk on medium-high speed until smooth.
2. In a stand mixer, beat the egg whites and remaining 1/4 cup sugar to medium-stiff peaks, then fold into the yolk and mascarpone mixture. Divide in half to use for both the beer version and hot chocolate version.
3. To make the beer version for adults: Pour the beer into a bowl or shallow dish. Working 1 at a time, dip 8 ladyfingers in the beer, turning to coat. Make a layer of dipped ladyfingers on the bottom of an 8-by-8-inch baking dish. Cover with a layer of the whipped mascarpone, then dip and layer 8 more ladyfingers and top with another layer of mascarpone. For a third time, dip and layer 8 more ladyfingers and top with the mascarpone mixture. Cover and refrigerate for at least 4 hours.
4. For the hot chocolate version: Pour the hot chocolate into a shallow dish. Working 1 at a time, dip 8 ladyfingers in the hot chocolate, turning to coat. Make a layer of dipped ladyfingers on the bottom of an 8-by-8-inch baking dish. Cover with a layer of the whipped mascarpone, then dip and layer 8 more ladyfingers and top with another layer of mascarpone. For a third time, dip and layer the remaining 8 ladyfingers and top with the remaining mascarpone mixture. Cover and refrigerate for at least 4 hours.
5. Top each of the desserts with 1/2 cup of the shaved chocolate before serving.
