1. Preheat your oven to 350°F and line a baking sheet with parchment paper.

2. Cream together the softened butter and granulated sugar until light and fluffy. Add the eggs and vanilla extract, mixing until well combined. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually incorporate the dry ingredients into the wet ingredients, mixing until the dough is fully combined.

3. Scoop the cookie dough onto the prepared baking sheet, spacing them evenly. Bake for 10-12 minutes, or until the cookies are lightly golden. Allow the cookies to cool completely on the baking sheet.

4. In a medium bowl, whip the heavy cream until soft peaks form. Add the powdered sugar and 1 teaspoon of vanilla extract, and continue whipping until stiff peaks form.

5. Spread or pipe the cream filling onto the bottom of one cookie, then top it with another cookie to create a sandwich.

6. In a small microwave-safe bowl, melt the semi-sweet chocolate chips with the vegetable oil in 20-30 second intervals, stirring until the mixture is smooth and glossy.

7. Drizzle or spread the melted chocolate glaze over the top of each cookie sandwich. Allow the chocolate to set before serving.
