In a stand mixer with a paddle attachment, cream butter and cream cheese. Add sugar and beat until light and fluffy. Add egg and vanilla and mix well. Scrape down sides and bottom of mixing bowl to make sure it’s well-combined.

Add flour, baking powder, and salt and mix until just combined.

Allow dough to chill for at least one hour.

Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius). Line two cookie sheets with Gefen Parchment Paper.

Place graham cracker crumbs into a small bowl.

Roll chilled cookie dough into one-inch (two-and-a-half-centimeter) balls. Roll each ball in graham cracker crumbs to coat and then flatten slightly on the cookie sheet.

Bake for 10 minutes.

Once cookies have cooled, drizzle with melted white chocolate if desired.
