Peanut Butter and Jelly Bars are soft, chewy, and easy to make with simple ingredients you already have—layered with sweet jam and a light peanut butter drizzle on top.
Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Line an 8×8 baking pan with parchment paper. Set aside.
In a medium-sized mixing bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
In the bowl of a stand mixer, combine the butter, sugars, and peanut butter. Beat till smooth, approximately 1–2 minutes. With the mixing speed on low, add the egg and vanilla, and mix until incorporated.
Slowly begin to add the dry ingredients. Mix until just combined. Remove the bowl from the stand and fold in the chopped peanuts.
Press ⅔ of the dough into the bottom of the prepared pan. Then pour the jam mixture on top. Smooth out. Place the remaining dough in dollops over the jam. Bake for 35–40 minutes or until the top begins to brown. Remove from the oven and let cool for 30 minutes.
Meanwhile, to prepare the drizzle, in a glass measuring cup, warm the milk in the microwave (10 seconds on HIGH). Add the vanilla and peanut butter, and mix until smooth. Gradually add in the powdered sugar. Once the mixture is smooth, drizzle over the cooled bars. Cut and serve.
