For bakers outside North America, drain 900 g of tub-style cream cheese through cheesecloth until it reaches approximately 680 g to match the density of brick-style cream cheese. For a gluten-free version, use certified gluten-free Speculoos cookies. For a vegan version, use block-style vegan cream cheese and vegan butter. Store refrigerated for up to 4 days or freeze individual slices for up to 3 months.
