Can you add to Kahlua a brownie recipe?

Ingredients:

- 1 cup (2 sticks) unsalted butter, softened

- 1 1/2 cups granulated sugar

- 1 teaspoon vanilla extract

- 3 eggs

- 1 cup all-purpose flour

- 1/2 cup unsweetened cocoa powder

- 1/4 teaspoon baking soda

- 1/4 teaspoon salt

- 1/4 cup Kahlua

- 1/2 cup chopped walnuts or chocolate chips (optional)

Instructions:

1. Preheat oven to 350 F degrees. Grease and flour an 8x8 inch baking pan.

2. In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the vanilla and eggs, one at a time, until well blended.

3. In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, alternating with the Kahlua, and mix until just combined. Do not overmix.

4. Fold in the chopped walnuts or chocolate chips, if desired.

5. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

6. Let the brownies cool completely before cutting and serving.

Enjoy your Kahlua brownies!
