Ingredients:

1 cup all-purpose flour

1/2 cup cornstarch

1/2 cup unsalted butter, softened

1/4 cup creamy peanut butter

1/2 cup granulated sugar

1 large egg

1 teaspoon vanilla extract

Pinch of salt

1/4 cup whole milk

Instructions:

1. Preheat and Prepare:

Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.

2. Cream Butter, Peanut Butter, and Sugar:

In a large mixing bowl, cream together the softened butter, peanut butter, and sugar until light and fluffy.

3. Add Egg and Vanilla:

Add the egg and vanilla extract to the butter-peanut butter mixture. Beat until well combined.

4. Mix Dry Ingredients:

In a separate bowl, whisk together the flour, cornstarch, and a pinch of salt.

5. Combine Wet and Dry:

Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms.

6. Add Milk:

Pour in the milk and continue to mix until the dough comes together. The dough should be smooth and soft.

7. Roll and Cut:

On a lightly floured surface, roll out the dough to about 1/8-inch thickness. You may want to divide the dough into two portions for easier rolling.

8. Cut into Shapes:

Use cookie cutters to cut the dough into desired shapes. Place the cutouts on the prepared baking sheets, leaving a little space between each.

9. Bake:

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden. Keep an eye on them to prevent over-baking.

10. Chill:

Allow the peanut butter wafer cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.

11. Serve or Store:

Once cooled, serve the peanut butter wafer cookies as they are or use them in various desserts. Store any leftovers in an airtight container to maintain their crispiness.

Optional Tips:

For an extra peanut flavor, you can sprinkle chopped peanuts on top of the cookies before baking.

Drizzle melted chocolate over the cooled cookies for a delightful chocolate-peanut butter combination.
