Preparation Steps for Peanut Butter and Jelly Crumble Bars

Now that you have your ingredients ready, let’s dive into the preparation of these delightful bars. Each step brings you closer to a sweet treat that you’ll love sharing. Follow along as we create something truly scrumptious.
Begin by preheating your oven to 350 degrees Fahrenheit. This step is crucial as it ensures your bars will bake evenly and thoroughly. While the oven is heating, line an 8-by-8-inch baking pan with aluminum foil. Make sure to spray it with cooking spray after lining it to prevent sticking. Setting the pan aside allows you to focus on the batter without interruption.
In a large, microwave-safe bowl, add the unsalted butter and heat it on high power for about 1 minute until fully melted. Watch closely to avoid any splattering. Once melted, it’s time to add the creamy peanut butter. Heat it for an additional 30 seconds to soften. This makes mixing easier and ensures the two ingredients blend perfectly.
Using a whisk, combine the melted butter and peanut butter until you achieve a smooth and creamy mixture. The goal is to create a luscious base. Allow the mixture to cool slightly before proceeding to the next step to avoid scrambling the egg when you add it.
Now, you can add the large egg, light brown sugar, and vanilla to the bowl. Whisk everything together until the mixture is smooth again. This step is essential for incorporating air, which will give your bars a nice texture.
Next, it’s time to add in the dry ingredients: all-purpose flour and salt. Gently stir them into the mixture until just combined. Be careful not to overmix, as this can lead to tough bars. You want a nice, thick batter that holds its shape.
Turn the batter out into the prepared pan, spreading it evenly across the bottom. Bake in the preheated oven for 15 minutes. This initial bake helps set the base layer for your bars, making them sturdy enough to support the topping.
While the bars are baking, let’s prepare the crumble topping. In another large, microwave-safe bowl, add the remaining unsalted butter and heat it until melted, similar to the first step. Once melted, add the all-purpose flour, old-fashioned rolled oats, granulated sugar, light brown sugar, and salt. Mix everything together until the mixture resembles a dry, sandy consistency with some larger crumble pieces, which will create that delightful texture.
After the bars have baked for 15 minutes, remove the pan from the oven. Spread the Smuckers Fruit and Honey Strawberry Fruit Spread evenly over the surface of the warm bars. Be sure to leave about a half-inch margin at the edges.
Sprinkle the crumble topping evenly over the fruit spread layer. This creates a beautiful contrast of textures and flavors. It’s okay if some of the fruit spread peeks through; it’ll add to the charm of your finished bars.
Return the pan to the oven and bake for about 25 to 28 minutes. You’ll know they’re done when the crumble topping is lightly golden brown and has set. Keep an eye on them during the last few minutes to prevent over-baking.
Once baked, remove the pan from the oven and place it on a wire rack to cool for at least 90 minutes. This cooling time is essential for the bars to hold their shape when sliced. Patience will pay off!
Finally, once cooled, lift the bars out of the pan using the foil edges and slice them into squares. Enjoy your homemade Peanut Butter and Jelly Crumble Bars!
Things Worth Knowing
