Make the chocolate pudding:

If you are using store-bought pudding then you don't need to prepare the pudding and you can make these dirt pudding cups in minutes. If you are making chocolate pudding using a box mix, follow the instructions on the box.

To make homemade chocolate pudding:

1. In a medium saucepan, whisk together sugar, cocoa powder, cornstarch, salt, and egg yolks until well blended. Whisk in the milk and heat over medium heat, stirring often, about 5-8 minutes.
2. Once the mixture starts to bubble, turn the heat down to low and continue cooking until thickened, whisking often, about 1-2 minutes more. Note that pudding will be pourable but will continue to thicken more as it cools.
3. Remove from heat and immediately whisk in the butter, melted chocolate, and vanilla, stirring until smooth.
4. If you notice any lumps, pass the pudding through a fine mesh sieve over a large heatproof bowl to remove any lumps. Skip this if you don’t notice any lumps.
5. Prepare a large bowl with some water and ice to make an ice bath. Place the saucepan directly into the ice bath, stirring occasionally, until the pudding reaches room temperature, about 30 minutes.
6. Cover and refrigerate until the pudding has chilled through completely, at least 4 hours (up to 2 days).

Assemble the dirt pudding cups

1. Use a food processor to crush the cookies. You can also place them in a Ziploc bag and roll a rolling pin over top to crush them. Set aside.
2. Divide the pudding into 4 separate small cups (1/2 cup pudding into each). Top each with crumbled oreos and place a few gummy worms on top.
3. Serve immediately or chill until ready to serve.
