Creating these Red Velvet Cake Ice Cream Sandwiches is simple if you follow these steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper.

2. Mix Dry Ingredients: In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until well combined.

3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar together until light and fluffy.

4. Add Egg and Flavorings: Beat in the egg, vanilla extract, red food coloring, and white vinegar. Mix until the color is uniform.

5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet mixture, stirring just until combined.

6. Chill the Dough: Cover the bowl with plastic wrap and refrigerate the dough for at least one hour. Chilling helps prevent the cookies from spreading too much while baking.

7. Scoop and Bake: Once chilled, scoop tablespoonfuls of dough onto the prepared baking sheet, leaving enough space between each. Bake for 12-15 minutes.

8. Cool: Remove from the oven and let the cookies cool on the baking sheet for about 10 minutes. Then, transfer them gently to wire racks to cool completely.

9. Fill with Ice Cream: Once cookies are completely cool, scoop your favorite ice cream onto the flat side of half the cookies. Top with the remaining cookies, pressing down gently.

10. Freeze Again: To help them hold shape, place the assembled sandwiches back in the freezer for at least 30 minutes before serving.
