To create your Maraschino Cherry Chocolate Chip Cookie Bars effortlessly, follow these step-by-step instructions:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it or lining it with parchment paper for easy removal.

2. Cream Butter and Sugars: In a large mixing bowl, combine the softened butter, granulated sugar, and brown sugar. Cream together until the mixture is light and fluffy.

3. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Mix until everything is well combined.

4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, baking soda, and salt.

5. Mix Dry and Wet Ingredients: Gradually add the flour mixture to the butter and sugar mixture, mixing just until combined. Be careful not to overmix.

6. Fold in Chocolate and Cherries: Gently fold in the chocolate chips and the chopped maraschino cherries until evenly distributed throughout the dough.

7. Spread the Dough: Pour the cookie dough into the prepared baking dish. Spread it evenly with a spatula to ensure uniform baking.

8. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.

9. Cool the Bars: Once baked, remove the dish from the oven and allow the cookie bars to cool in the pan for about 10-15 minutes. This will help them set properly.

10. Cut into Squares: When cool, transfer the bars to a cutting board and slice them into squares. For extra flair, you can add sprinkles on top before serving.

These straightforward instructions will have you enjoying your delicious Maraschino Cherry Chocolate Chip Cookie Bars before you know it!
