Introduction
If you ever had a peanut butter and jelly sandwich tucked into your lunchbox, this one’s gonna hit home. Now imagine that same combo—sweet jelly and rich peanut butter—not on bread, but soaked into a soft, fluffy cake. Yeah, we’re talking about a dessert that brings the "wow" with every bite. This isn’t just any cake—it’s a PB&J cake that looks fancy, tastes even better, and is secretly super simple. It’s perfect for birthdays, potlucks, or just because your kitchen deserves something awesome.
Why This Works
The magic here? Peanut butter and jelly already go together like best friends. One’s salty, one’s sweet, and they balance each other out. Toss those flavors into a cake and you've got something that tastes like it took hours—but didn’t. The ingredients are common pantry stuff, nothing fancy. The “poke” trick lets the PB&J mixture soak into every inch of the cake. When it cools, each slice has that beautiful marbled look that makes people think you went full pastry chef—even if it’s your first cake.

Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup whole milk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup creamy peanut butter
- 1/2 cup grape or strawberry jelly
- 1 cup powdered sugar
- Optional: whipped cream or more peanut butter for topping
Instructions
- Step 1: Heat Things Up
Start by setting your oven to 350°F (175°C). Grab a 9x13-inch baking dish and grease it up with butter or non-stick spray. This helps the cake come out clean later. - Step 2: Mix It Like a Pro
In one bowl, whisk together flour, sugar, baking powder, and salt. In a bigger bowl, mix butter, milk, eggs, and vanilla until smooth. Slowly add the dry stuff to the wet stuff. Stir just until everything is combined. No need to go wild with the whisk—overmixing makes the cake dense. - Step 3: Bake Time
Pour that batter into your prepared pan and smooth the top. Bake it for 25 to 30 minutes. It’s done when a toothpick stuck in the center comes out clean. Let it rest for about 5 minutes, but don’t walk away yet—things get fun here. - Step 4: Poke & Pour
While the cake’s still warm, use a fork or skewer to poke holes all over the top. Mix the peanut butter and jelly in a small bowl until it’s smooth. Pour this mix right over the cake, letting it seep into the holes. That’s the “poke cake” magic. Let it cool completely before finishing. - Step 5: Sweet Finish
Once cool, dust the top with powdered sugar. Want to be extra? Add whipped cream or a little more peanut butter on top before slicing and serving.
Helpful Tips
- If your cake turns out dry, you may have overbaked or mixed too much. Keep an eye on both.
- Jelly options? Try raspberry, blueberry, or even apricot. Each gives a whole new flavor vibe.
- Want a nuttier punch? Use natural peanut butter—it has a deeper flavor.
- Mix the jelly and peanut butter while the cake bakes, so it's ready when it's poke time.
Heat Control
Stick to 350°F. Don’t guess. Preheating matters, and so does keeping the oven door closed. The cake bakes for 25–30 minutes. You’ll know it’s ready when the top turns golden and a toothpick comes out clean. If it comes out sticky or wet, give it a few more minutes. If it’s dry or cracked—too long, friend.
Crunch Factor
This cake’s not meant to crunch—it’s all about soft, velvety goodness. The jelly and peanut butter mix sinks into the cake while it’s still warm, locking in that melt-in-your-mouth feel. You’re going for moist and rich, not dry and crumbly. If that’s the texture you’re getting, you’re baking it too long.
Pro Kitchen Tips
- Grease your pan well or line it with parchment paper. Trust me—clean-up becomes a breeze.
- Want a stronger peanut butter flavor? A few drops of peanut butter extract in the batter will do the trick.
- For easy clean-up, mix the filling in a microwave-safe bowl. It makes the peanut butter easier to stir, and you’ll save your wrists.
Storage Tips
- Keep leftovers at room temp for up to 3 days. Just wrap the dish tight with foil or plastic wrap.
- Planning ahead? This cake stores well in the fridge for 5 days or the freezer for 2 months. If freezing, skip the powdered sugar until serving day.
- Serving from the fridge? Let slices sit out for a few minutes to soften, or microwave briefly for a warm bite.
Gift Packaging Ideas
Slice it, wrap it in wax paper, then tuck it into a treat box or tin. Tie a ribbon around it, add a note, and boom—instant homemade gift. If you're gifting a full cake, go with a baking dish that looks good and can travel. Your friends will think you went gourmet bakery mode.
Flavor Variations
- Add a pinch of cinnamon or sea salt for extra flavor depth.
- Toppings? Think chopped peanuts, crushed pretzels, or chocolate chips for texture.
- Want to mix things up? Use almond butter or cashew butter instead of peanut butter. Each one brings its own twist.
- Gluten-free? Use a 1:1 gluten-free flour blend—works like a charm.

Troubleshooting
- Cake too dense? You may have overmixed. Stir gently next time.
- Tastes dry? Check your oven temp—it may run hot.
- Missing ingredients? Swap milk with almond milk, or use honey instead of sugar (though it changes the flavor).
- Watch the top—if it browns too fast, cover it loosely with foil halfway through baking.
FAQs
- Can I freeze this cake?
Yes! Up to 2 months. Just hold off on powdered sugar until you thaw and serve. - Is it gluten-free?
Not as-is, but it can be. Swap regular flour with a gluten-free mix that works cup-for-cup. - Can I double it?
Definitely. Use a larger baking dish and check for doneness by testing the center.
