Crush the Oreo cookies into fine crumbs using a food processor.
Mix the crushed Oreos with softened cream cheese until fully combined into a dough-like consistency.
Scoop out portions of the mixture and shape them into egg shapes. Place them on a parchment-lined baking sheet.
Refrigerate the shaped eggs for 30 minutes to firm up.
Melt the white chocolate in a microwave-safe bowl, heating in 30-second intervals and stirring between each until smooth.
Divide the melted chocolate into separate bowls and add different pastel food colorings, stirring until well blended.
Dip each chilled Oreo egg into the colored chocolate, allowing the excess to drip off before placing it back on the parchment paper.
Decorate with sprinkles or edible decorations while the chocolate is still wet.
Let the truffles sit at room temperature until the chocolate sets completely.
