Begin by melting the unsalted butter in a large saucepan over low heat. Stir it gently to ensure it melts evenly without browning.
Once the butter is completely melted, add the mini marshmallows to the saucepan. Stir constantly until all the marshmallows have melted and the mixture is smooth and creamy.
Remove the saucepan from the heat source. Stir in the vanilla extract and cocoa powder, mixing thoroughly until fully combined and there are no lumps.
Gradually fold in the Rice Krispies cereal, using a spatula to mix gently until every piece is evenly coated in the marshmallow mixture.
Allow the mixture to cool for about 5 minutes. Then, add the dried cranberries and chopped pecans, stirring until they are evenly distributed throughout the mixture.
Lightly grease a muffin tin with cooking spray or butter. Firmly press the Rice Krispie mixture into the cups of the muffin tin, shaping them into little pudding forms. Ensure they are compact for a better hold.
Let the puddings set for about 30 minutes at room temperature, or until they have firmed up adequately.
While the puddings are setting, melt the white chocolate chips. Place them in a microwave-safe bowl and microwave in 30-second intervals, stirring between each interval until the chocolate is completely melted and smooth.
Once the Rice Krispie puddings are firm, carefully remove them from the muffin tin, using a butter knife around the edges if necessary.
Drizzle the melted white chocolate over the top of each pudding in a decorative manner. Finish by sprinkling with red and green sprinkles to add a festive touch.
Notes
Arrange the finished puddings on a vibrant Christmas-themed platter for a cheerful display.
