Prepare the cookie dough by creaming together butter and sugar until light and fluffy. Beat in eggs one at a time, then mix in vanilla and dry ingredients until just combined.

Chill the dough in the refrigerator for about 30 minutes to firm it up.

Preheat the oven to 350°F (175°C). Scoop dough, shape into balls, and place on a greased baking sheet. Bake for about 12 minutes or until edges are golden.

Make the cream filling by whisking heavy cream, powdered sugar, and vanilla extract until stiff peaks form.

For the glaze, melt chocolate chips and vegetable oil in a double boiler or microwave until smooth.

Assemble cookies by sandwiching cream filling between two cookies and dipping the tops in the chocolate glaze.
