These peanut butter and jelly bars bring together two flavors that have always belonged together. The cookie dough is rich and tender rather than dry, the raspberry jam adds a vivid fruity layer, and the salted peanuts provide a satisfying contrast to the sweetness.
The method is also wonderfully forgiving. The bottom dough does not need to be perfectly sculpted, and the remaining dough is simply dotted over the jam, creating a rustic, crumbly top that looks inviting straight from the oven.
This recipe makes about 24 bars, so it is a practical choice when you need a generous dessert. Cut them into smaller squares for a party platter, or make larger bars for an after-school treat.

Ingredients You’ll Need
The ingredient list is straightforward, but each item has an important job. Softened unsalted butter creates the rich foundation, while granulated sugar sweetens the dough and helps it bake into a golden cookie layer.
- Butter and sugar: Use butter softened to room temperature so it creams smoothly with the sugar.
- Eggs and vanilla: Two extra-large room-temperature eggs add structure and richness, while vanilla rounds out the peanut butter flavor.
- Peanut butter: Smooth peanut butter gives the bars their signature taste and a cohesive cookie dough.
- Flour, baking powder, and salt: These form the dry foundation. Kosher salt is especially helpful because it balances the sweetness.
- Raspberry jam: Its bright color and tart fruit flavor cut through the richness of the peanut butter.
- Salted peanuts: Coarsely chopped peanuts add a crisp, savory finish to the soft bars.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F and prepare the pan. Grease a 9 x 13-inch baking pan, or line it with parchment paper and leave an overhang on two sides. The parchment will make it much easier to lift the cooled slab out for neat cutting.
Step 2: Cream the softened butter and granulated sugar in a large bowl until light and fluffy. This usually takes a few minutes of mixing, and the finished mixture should look smooth rather than dense.
Step 3: Add the vanilla and eggs. Beat in the vanilla first, then add the eggs one at a time, mixing after each one. Room-temperature eggs blend into the butter mixture more readily and help create an even dough.
Step 4: Mix in the peanut butter. Stir until the mixture is uniform and no streaks of butter or peanut butter remain. Smooth peanut butter works best for the texture specified in this recipe.
Step 5: Combine the dry ingredients separately. Whisk together the flour, baking powder, and kosher salt in another bowl, then gradually add this mixture to the peanut butter mixture. Stop mixing as soon as the dough comes together so the bars stay tender.
Step 6: Build the bottom layer. Spread about two-thirds of the dough evenly across the prepared pan. Use a spatula or lightly floured fingertips to press it into the corners and create an even foundation.
Step 7: Add the raspberry jam. Spread 1 1/2 cups of jam over the dough, leaving a small margin around the edges. Keeping the jam slightly away from the sides helps prevent it from bubbling over the pan during baking.
Step 8: Add the top dough. Break the remaining dough into small pieces and scatter them over the jam. Do not worry about covering every bit; visible patches of raspberry jam give the bars their appealing homemade look.
Step 9: Finish with peanuts. Sprinkle 2/3 cup of coarsely chopped salted peanuts over the dough pieces. Press them very lightly if needed, but avoid compacting the topping.
Step 10: Bake for about 45 minutes. The top should be golden brown, the edges should look set, and the center should be set while still somewhat soft. Cool the pan thoroughly for at least 30 minutes before lifting and slicing.
Pro Tips for Tender, Clean-Cut Bars
Begin with butter and eggs at room temperature. Cold ingredients can leave the mixture uneven, while room-temperature ingredients combine into a smoother dough with less effort.
Measure the flour carefully and avoid packing it tightly into measuring cups. Too much flour can make the cookie layers heavy, so spoon the flour into cups and level it if you are measuring by volume.
Do not try to spread the jam all the way to the edges. A narrow border gives the jam room to move as it heats and keeps the finished bars easier to handle.
The most important baking clue is the center. These bars should not look wet or loose, but they should retain a little softness when they come out of the oven. They firm as they cool, so baking until completely hard can produce a dry result.
For a neat presentation, cool the bars in the pan before lifting them out with the parchment. Use a sharp knife and wipe the blade between cuts for defined layers.

Serving Suggestions
Serve these bars at room temperature when the peanut butter flavor is fullest and the jam has a soft, chewy consistency. They are delicious with coffee, tea, cold milk, or a scoop of vanilla ice cream.
For a dessert tray, arrange the bars with the jam side visible and add a light dusting of powdered sugar only if desired. The chopped peanuts already provide a lovely finish, so extra decoration is not necessary.
They also fit beautifully into seasonal baking spreads. If you are planning a festive menu, pair them with a slice of festive Christmas Love Cake for a colorful assortment of homemade sweets.
Storage and Make-Ahead Advice
Let the bars cool fully before storing them so trapped warmth does not create excess moisture. Keep them in an airtight container at room temperature for several days, placing parchment between layers if stacking.
For longer storage, wrap the cooled bars well and freeze them in an airtight freezer-safe container. Thaw them at room temperature before serving, then slice or arrange them once they are fully softened.
If you want to prepare ahead for a gathering, bake the bars the day before. Their texture remains rich and tender after resting, and the layers are often easier to cut once they have had time to settle.
