Step‑by‑Step Instructions for Peanut Butter and Jelly Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, line a 9×13-inch baking dish with parchment paper, allowing some overhang for easy removal later. This will ensure the Peanut Butter and Jelly Bars bake evenly and can be easily lifted out when ready to cut.
Step 2: Cream Together Ingredients
In a standing mixer, combine the softened unsalted butter, creamy peanut butter, and sugar. Beat the mixture on medium speed for about 2–3 minutes until it becomes light and fluffy, creating a creamy base for your bars. This step is crucial as it incorporates air, giving your bars that delightful texture.
Step 3: Incorporate Eggs and Vanilla
Add the eggs one at a time into the creamy mixture, mixing well after each addition until fully combined. Then, gently stir in the vanilla extract to enhance the flavors. The mixture should be smooth and slightly voluminous, ready for the dry ingredients to be folded in.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder until they are well blended. Gradually add this dry mixture into the wet ingredients in your standing mixer, mixing on low speed until just combined. Be careful not to overmix; you want the dough to remain tender for your Peanut Butter and Jelly Bars.
Step 5: Form the Base Layer
Take about two-thirds of the dough and evenly press it into the bottom of the prepared baking dish. Use your hands or a spatula to ensure the layer is smooth and evenly distributed. This base layer will provide the perfect foundation for your jam and crumble topping.
Step 6: Spread the Jam
Now, spread a generous layer of strawberry jam over the pressed dough. Aim for an even coverage, allowing the sweetness of the jam to flow into every bite of your Peanut Butter and Jelly Bars. Ensure the base layer remains intact as you spread to maintain its structure.
Step 7: Crumble the Top Layer
With the remaining dough, crumble it evenly over the layer of strawberry jam. This creates a topping that will crisp up beautifully in the oven. Make sure to leave some gaps for the jam to peek through, allowing for a delightful presentation when baked.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 30-35 minutes. Keep an eye on the bars; you’re looking for a lightly golden brown color on top. The edges should be firm while the center may still be a bit soft, signaling that they’ll set up as they cool.
Step 9: Cool and Slice
Once baked, remove the Peanut Butter and Jelly Bars from the oven and let them cool completely in the pan. This cooling period is essential for achieving the right texture. Once cooled, use the parchment paper overhang to lift the bars out and slice them into squares for serving.
Expert Tips for Peanut Butter and Jelly Bars
Room Temperature Eggs: Ensure your eggs are at room temperature for better incorporation into the batter, resulting in a fluffier texture.
Avoid Overbaking: Keep an eye on the bars as they bake. Checking for doneness at the lower end of the time will help keep them soft and chewy.
Use Parchment Paper: Lining your baking dish with parchment makes it easier to lift out the Peanut Butter and Jelly Bars, allowing for clean cuts and no sticky mess.
Don’t Overmix: When combining wet and dry ingredients, mix just until combined to prevent tough bars. A tender dough is key for that perfect chew!
Even Jam Layer: Spread the jam evenly, but don’t press it too hard; this ensures a delightful fruity flavor in every bite without compromising the base layer.
Flavor Variations: Experiment with different jams or add-ins, like chocolate chips or nuts, to customize these bars to your family’s taste preferences.
