Making Boston Cream Pie Cookies can be simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Mix Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Scoop Dough: Using a cookie scoop or tablespoon, drop the dough onto the prepared baking sheet, spacing them about 2 inches apart.
7. Bake: Bake in the preheated oven for 15-20 minutes, or until the edges are lightly golden. Remove from the oven and cool on a wire rack.
8. Prepare Cream Filling: In a medium bowl, whip together the heavy cream, powdered sugar, and vanilla extract until soft peaks form.
9. Fill Cookies: Once the cookies are completely cool, spoon or pipe the cream filling onto the bottom of half the cookies, then top with the remaining cookies to create sandwiches.
10. Make Chocolate Glaze: In a microwave-safe bowl, combine the chocolate chips and butter. Microwave in 30-second intervals, stirring in between, until melted and smooth.
11. Glaze Cookies: Dip the tops of the filled cookies into the chocolate glaze, allowing any excess to drip off. Place them back on the wire rack to set.
