Peanut Butter and Jelly Bars — Do This Next

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and grease or line your baking dish with parchment paper for easy removal.
Step 2: Cream Butter and Sugar
In a large mixing bowl, combine the room temperature butter and granulated sugar. Use your electric mixer to beat until light and fluffy, about 2-3 minutes.
Step 3: Add Eggs and Vanilla
Add the eggs and vanilla extract to the butter mixture. Beat until combined, ensuring everything is well-incorporated.
Step 4: Incorporate Peanut Butter
Next, add the creamy peanut butter to the mixture. Beat until the peanut butter is fully integrated and the mixture is smooth.
Step 5: Mix Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder. Gradually add this to the wet mixture, mixing on low speed until just combined.
Step 6: Spread the Batter
Spread about two-thirds of the peanut butter batter into the prepared baking dish, smoothing it into an even layer.
Step 7: Add Jam
Spoon your favorite jam over the batter, spreading it gently to cover as much as possible without disturbing the base layer.
Step 8: Finish with Batter
Dollop the remaining peanut butter batter over the jam layer. Use a spatula to spread it out gently, ensuring some of the jam is still visible.
Step 9: Optional Peanuts
If using, sprinkle the coarsely chopped salted peanuts on top of the batter for added texture and crunch.
Step 10: Bake
Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Step 11: Cool and Dust
Let the bars cool in the pan for at least 10 minutes, then transfer to a wire rack to cool completely. Dust with powdered sugar before slicing into squares.
Holiday & Seasonal Touches
