Instructions
Make the Crust
In a food processor or a blender, pulse 6 chocolate sandwich cookies (with cream filling) into a fine crumb. You can also place them in a zip-top bag and crush them into fine crumbs with a rolling pin. Alternatively, you can use ½ cup of premade chocolate cookie crumbs.
Stir the melted butter into the chocolate crumbs until well combined.
Place the crumb mixture in a 4½" to 5" shallow dish or ramequin. Press the mixture equally, up the sides of the dish and on the bottom, to create the crust. Refrigerate the crust while preparing the filling.
Make the Filling
Measure out the ¼ cup of chocolate chips into a microwave safe bowl. Microwave for 1m20s, stirring vigorously every 30 seconds, being careful not to over heat the chocolate.
While the chocolate is still melted and warm, whisk in the sour cream until smooth. Add the maple syrup to the chocolate mixture and whisk to combine.
Assemble the Tart
Slice half a banana into ¼ inch slices. Cover the bottom of the chilled crust with a single layer of the sliced banana. Pour the sour cream chocolate ganache carefully over the banana slices, using the back of a spoon to spread the mixture.
Garnish the tart with the remaining banana slices and the optional flaky sea salt. Serve right away or return to the refrigerator until ready to eat.
