1-Getting started: Getting started with peanut butter bars is simple and fun, perfect for home cooks of all levels. Begin by preheating your oven to 350°F and lining a 9×13-inch pan with foil or parchment paper for easy removal; grease it lightly to prevent sticking. This step ensures your bars come out cleanly and helps with the overall baking process.

2-Gathering and Mixing Ingredients: In a microwave-safe bowl, melt the unsalted butter and creamy peanut butter until smooth, which takes just a minute or two. Add the light brown sugar and whisk it in until fully combined, creating a rich base for your bars. Next, whisk in the large eggs and pure vanilla extract, making sure to scrape the sides of the bowl for an even mix.

Once the wet ingredients are ready, combine the all-purpose flour, baking powder, and salt in a separate bowl. Stir the dry ingredients into the wet mixture just until no flour streaks remain, being careful not to overmix this keeps the bars soft and chewy. Spread the batter evenly in your prepared pan and bake for 17-20 minutes, or until they turn a light golden brown.

3-Adding the Icing and Finishing Touches: While the bars cool on a wire rack, prepare the icing by heating the unsalted butter, creamy peanut butter, and milk in a saucepan until it simmers, then remove from heat. Whisk in the pure vanilla extract and powdered sugar until smooth, resulting in a luscious topping that elevates the bars. Pour the icing over the warm bars, spreading it evenly, and sprinkle with chopped roasted salted peanuts and flaky sea salt, pressing the peanuts lightly into the frosting.

Allow the bars to cool completely until the frosting sets before cutting them into pieces.
