What You’ll Need
To create this flavorful poke cake, you will need a standard yellow cake mix, which we elevate with real peanut butter and butter. The filling is made with melted strawberry jam, and the frosting is a homemade blend of peanut butter and whipped topping. You will also need a 9×13 baking pan and a wooden spoon to create those signature poke holes.
Ingredient Notes
- Peanut Butter – You can use either creamy or chunky peanut butter depending on your preference. Creamy provides a smoother frosting, while chunky adds extra texture to the cake base.
- Strawberry Jam – This serves as the jelly component. Melting it slightly ensures it flows perfectly into the holes of the cake for a marbled effect.
- Yellow Cake Mix – This provides a reliable, sweet foundation that pairs beautifully with the savory notes of the peanut butter.
- Whipped Topping – Using a stabilized whipped topping ensures the frosting stays fluffy and holds its shape on top of the cake.
Add-ins and Substitutions
- Jam Varieties – While strawberry is classic, grape, raspberry, or blackberry jam are all delicious alternatives for the filling and drizzle.
- Nut-Free Option – If catering to allergies, a sunflower seed butter can be substituted for the peanut butter, and the chopped peanuts can be omitted.
- Extra Crunch – You can add 1/2 cup of peanut butter chips to the cake batter before baking for even more peanut flavor.
How to Make Peanut Butter and Jelly Poke Cake
The secret to a great poke cake is ensuring the jam fills every crevice while the cake is still warm enough to absorb it.
- Prepare the Batter: Preheat your oven to 350 degrees. In a large bowl, combine the yellow cake mix and 1 cup of the peanut butter. Stir until the mixture looks crumbly. Add the eggs, milk, and melted butter. Blend at low speed until moistened, then beat on high speed for 2 minutes to aerate the batter.
- Bake the Cake: Pour the batter into a greased 9×13 pan. Bake for 35-45 minutes, or until a toothpick inserted in the center comes out clean.
- The Poke Step: Remove the cake from the oven and let it cool on a wire rack for exactly 15 minutes. While it is still warm, use the end of a wooden spoon to poke holes across the entire surface of the cake.
- Fill with Jam: Microwave 1 cup of the strawberry jam for about 30 seconds until it is thin and pourable. Carefully pour the jam over the cake, ensuring it fills the holes. Allow the cake to cool completely for about an hour.
- Whisk the Frosting: While the cake cools, beat 1/2 cup of peanut butter with an electric mixer on high for 2 minutes until light. Gently fold in the whipped topping, 1/3 at a time, until the frosting is well blended and fluffy.
- Final Assembly: Spread the peanut butter whipped topping over the cooled cake.
- Drizzle and Garnish: Microwave the remaining 1/4 cup of jam and 1/4 cup of peanut butter in separate bowls for 10 seconds each. Drizzle both over the top of the frosting and sprinkle with chopped peanuts.
Pro Tip: When folding the whipped topping into the peanut butter, use a gentle hand. Adding it in three separate batches prevents the whipped topping from deflating, ensuring your frosting stays high and airy.
Recipe Tips
- Hole Placement: Space your holes about 1 inch apart to ensure every slice gets a perfect amount of jam filling.
- Don’t Rush the Cooling: Ensure the cake is completely cool before adding the whipped topping. If the cake is still warm, the frosting will melt and slide off.
- Clean Slices: For the cleanest squares, wipe your knife with a warm, damp cloth between each cut.
- Microwave Caution: When thinning the jam and peanut butter for the drizzle, only heat in short 10-second bursts to avoid burning the sugars.
FAQs
Can I use a different cake mix? Yes, a white cake mix or even a chocolate cake mix works well, though yellow cake mix provides the most traditional “PB&J” flavor profile.
Does this cake need to be refrigerated? Yes, because of the whipped topping and the jam filling, this cake should be stored in the refrigerator to stay fresh and food-safe.
Can I use natural peanut butter? Natural peanut butter that requires stirring may be too oily for the frosting. It is best to use a stabilized, traditional brand for the best consistency.
Serving Suggestions
- With Milk – This rich cake is best served with a cold glass of milk to balance the peanut butter.
- Celebrations – This is a fantastic alternative to a traditional birthday cake for someone who loves nostalgic flavors.
- Platter Style – Slice into smaller squares and serve on a large platter for a party-friendly dessert.
Make This Recipe in Advance
You can bake the cake and fill it with jam a day in advance. Store it covered in the refrigerator. When you are ready to serve, whip up the frosting and add the toppings. This allows the jam to really soak into the cake, making it even more moist. Once fully assembled, the cake will keep well in the refrigerator for up to 3 days.

Description
The ultimate nostalgic treat, bringing the classic flavors of a PB&J sandwich into a moist, decadent cake. Featuring a peanut butter-infused base, a sweet strawberry jam filling, and a fluffy peanut butter whipped frosting, this cake is a guaranteed hit for any gathering.
Ingredients
- 1 (15.25 oz) yellow cake mix
- 4 large eggs, 1 1/4 cups milk
- 1/2 cup salted butter (melted)
- 1 3/4 cups peanut butter (divided)
- 1 1/4 cups strawberry jam (divided)
- 1 (8 oz) container whipped topping (thawed)
- 1/4 cup peanuts (chopped)
Instructions
Batter: Preheat oven to 350°F. Combine cake mix and 1 cup peanut butter until crumbly. Add eggs, milk, and melted butter; beat on high for 2 mins.
Bake: Pour into a greased 9×13 pan. Bake for 35–45 mins. Cool for exactly 15 mins.
Poke & Fill: Poke holes 1 inch apart with a wooden spoon handle. Microwave 1 cup jam for 30 seconds; pour over cake into holes. Cool completely.
Frost: Beat 1/2 cup peanut butter until light. Fold in whipped topping by hand. Spread over cake.
Garnish: Drizzle with warmed remaining jam and peanut butter. Top with chopped peanuts.
Notes
The ‘Poke’ Timing: Cooling for 15 minutes is the ‘sweet spot’—it allows the jam to absorb into the crumb without making the cake soggy.
Frosting Texture: Always fold the whipped topping into the peanut butter by hand. An electric mixer will deflate the air and result in a heavy, flat frosting.
Storage: This cake must be refrigerated. It actually tastes better on day two once the jam has fully permeated the sponge!
