Stepwise Method: BEST Peanut Butter Bars

Step 1: Prepare Your Dish
Start by lining your 9×9-inch baking dish with parchment paper. This will help you lift the bars out easily once they are set.
Step 2: Make the Base
In a large mixing bowl, combine the melted unsalted butter and Ritz cracker crumbs. Stir until the crumbs are fully coated and the mixture resembles wet sand.
Step 3: Add the Sweetness
Next, add the powdered sugar to the crumb mixture. Mix well until fully incorporated. The mixture should be slightly sticky.
Step 4: Incorporate Peanut Butter
Now, stir in ¾ cup of creamy peanut butter until the mixture is smooth and well combined. The peanut butter adds a rich flavor and binds the bars together.
Step 5: Transfer to Baking Dish
Press the mixture evenly into the bottom of your prepared baking dish. Use a spatula to smooth it out, ensuring it is packed down firmly.
Step 6: Melt the Chocolate
In a microwave-safe bowl, heat the chocolate chips in 30-second intervals, stirring in between until fully melted and smooth. Be careful not to overheat.
Step 7: Add the Chocolate Layer
Pour the melted chocolate over the peanut butter base, spreading it evenly with a spatula.
Step 8: Final Touches
Drizzle the remaining 2 tablespoons of peanut butter over the melted chocolate, and use a knife to swirl it for a beautiful marbled effect.
Step 9: Chill and Set
Place the baking dish in the refrigerator for at least 2 hours or until the bars are completely set.
Swap Guide

- Gluten-Free Option: Substitute Ritz crackers with gluten-free crackers or graham crackers.
- Nut Butter: Swap peanut butter for almond butter or sunflower seed butter for a different flavor.
- Chocolate Alternatives: Use white chocolate chips or butterscotch chips for a unique twist.
- Sweetener Options: If you prefer a less sweet bar, reduce the amount of powdered sugar or use a sugar substitute.
