The other afternoon, while cleaning out the pantry, a jar of strawberry jam peeked out from behind the flour. In an instant, childhood came rushing back, lazy afternoons spreading jam on warm toast while the scent of peanut butter filled the kitchen. That tiny moment sparked an idea: why not take those simple, nostalgic flavors and turn them into something a bit more indulgent?
I grabbed a handful of peanut butter and decided to combine it with the jam in a new way. As I creamed the butter and sugar together, the kitchen filled with a warm, nutty scent that made me nostalgic. I imagined little squares of sweet and salty goodness that could brighten a weekday afternoon or surprise someone at a potluck.
By the time the bars were assembled with their golden crumble topping, I couldn’t help but admire how a few simple ingredients could transform into a dessert that looked inviting and promised comfort with every bite. The balance of creamy peanut butter, sweet jam, and buttery crumble felt like a playful twist on a timeless classic.

Cooking Instructions
Step 1: Prepping the Oven and Baking Dish
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy removal of the bars after baking.
Step 2: Creaming the Butter, Peanut Butter, and Sugar
In a standing mixer, blend 1 cup of softened butter, 2 cups of creamy peanut butter, and 1 ½ cups sugar until light and fluffy, about 3-4 minutes. Properly creamed, the mixture will form a rich, creamy base that’s smooth and slightly airy.
Step 3: Incorporating the Eggs and Vanilla
Add 2 large eggs one at a time, mixing thoroughly after each addition. Then stir in 1 teaspoon pure vanilla extract to enhance the flavor depth of the dough.
Step 4: Combining Dry Ingredients
In a separate bowl, whisk together 3 cups flour and 1 teaspoon baking powder. Gradually fold the dry ingredients into the wet mixture until a thick, cookie-dough-like consistency forms.
Step 5: Creating the Base Layer
Press approximately 2/3 of the dough evenly into the prepared baking dish, forming a solid, uniform foundation for the jam layer.
Step 6: Spreading the Jam
Spread 2 cups of strawberry jam evenly over the base layer, leaving a small border near the edges to prevent overflow during baking.
Step 7: Crumbling the Top Layer
Crumble the remaining dough over the jam, creating a textured, visually appealing top layer.
Step 8: Baking the Bars
Bake in the preheated oven for 30-35 minutes until the top turns a light golden brown. Monitor closely in the final minutes to avoid over-baking.
Step 9: Cooling and Cutting
Allow the bars to cool completely in the pan. Lift them out using the parchment overhang and cut into squares or rectangles for serving.
