Prepare pie crust according to package directions (for a single crust pie). Allow pie crust to cool.
In a small microwave bowl, melt baking chocolate on high heat for one minute. Stir and heat again in 15 second intervals until melted and smooth. Set aside to cool.
In a large saucepan over low heat, add eggs with sugar. Whisk over low heat until the temperature reaches 160 degrees F. Do not over heat (we don't want scrambled eggs).
Remove from heat and add in the cooled, melted chocolate. Beat for about 5 minutes. Set this aside.
In a mixing bowl, beat butter until light and fluffy, about 3 minutes. Add in the chocolate mixture with the vanilla extract. Beat just until fully combined.
Pour into the cooled pie crust.
Beat the heavy cream for 3 minutes until it begins to form stiff peaks. Slowly add in the powdered sugar and beat until fluffy! Spread over the top of the chocolate filling. Refrigerate pie for at least two hours (or overnight).
For the chocolate curls (or pieces), melt chocolate chips in microwave dish for one minute. Stir until smooth, heating by additional 15 second increments until fully melted. Spread over a large piece of parchment paper, until very VERY thin. Roll parchment paper up into a tube shape (like a paper towel tube). Refrigerate until ready to add the garnish, at least 30 minutes. Unroll parchment paper and the pieces will break off into shards. Place on top of pie when ready to serve.

Notes
Be sure to let the melted chocolate cool slightly before adding to the mixture.
I prepare this pie the night before. This allows it to set up completely!
Use a hot knife, and wipe it clean between slices, to get a perfect slice of pie.
Skip the chocolate curls and use about 1/2 cup of chocolate chips instead.
Storage- Keep pie covered in the refrigerator for up to 5 days. Or freeze for up to 30 days in an airtight freezer safe container.
