In a medium bowl, whisk together the vanilla instant pudding mix and cold milk until well combined, about 2 minutes. Let it set for an additional 5 minutes until creamy and smooth.

Divide the pudding mixture into two separate bowls. Add a few drops of different food coloring to each bowl and gently fold in the colors until fully blended and vibrant.

Select individual serving cups or jars. Begin by adding one tablespoon of finely crushed Oreo cookies into each cup, creating a solid base layer.

Alternate between the colorful pudding and crushed Oreo cookie layers in each cup until filled, ensuring the last layer is topped with crushed cookies.

Combine shredded coconut with a few drops of green food coloring in a sealed container. Shake until evenly tinted.

Sprinkle the tinted shredded coconut on top of each cup and add candy eggs and Peeps for decoration.

Chill the assembled Easter Dirt Cups in the refrigerator for at least 1 hour before serving.
