Homemade Oreos with Black Cocoa

Instructions:

1. Whisk together flour, black cocoa powder, baking soda, and salt in a bowl to remove lumps.
2. In a separate bowl, beat the softened butter and sugar until smooth. Mix in the egg and vanilla extract.
3. Slowly add the dry ingredients to the wet. Mix until a stiff dough forms; do not overwork the dough.
4. Wrap the dough and refrigerate for 30 minutes to prevent excessive spreading.
5. Scoop tablespoon-sized balls, place on parchment paper, and flatten with a flat-bottomed glass. Bake at 350°F (175°C) for 8–10 minutes.
6. Beat the softened butter for the filling until pale and fluffy.
7. Gradually add sifted powdered sugar on low speed to avoid a sugar cloud.
8. Mix in vanilla and heavy cream. Beat on high for 2 minutes until the texture is airy and holds a stiff peak.
9. Pipe or spoon filling onto the center of one cooled wafer and top with another wafer to assemble the sandwich.
