This Peanut Butter and Jelly Poke Cake is a fun twist on the classic sandwich, made into a sweet and creamy dessert. A moist vanilla or yellow cake is filled with strawberry jam, then topped with a fluffy peanut butter frosting and a drizzle of jelly. It’s the perfect nostalgic treat for parties, potlucks, or just because!
For the Cake:
1 box yellow cake mix (plus ingredients listed on the box: eggs, oil, water)
1 cup strawberry jelly or jam (slightly warmed for easier pouring)
For the Peanut Butter Frosting:
1 cup creamy peanut butter
1/2 cup unsalted butter, softened
2 cups powdered sugar
1/4 cup milk (plus more as needed)
1 tsp vanilla extract
Topping:
1/4 cup strawberry jelly or jam (for drizzling)
Crushed peanuts or chopped peanut butter cups (optional)
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
Prepare and bake the cake according to the package instructions. Let it cool for about 10 minutes.
Using the end of a wooden spoon or a straw, poke holes all over the cake.
Warm 1 cup of jelly slightly in the microwave until pourable. Pour it evenly over the cake, letting it soak into the holes.
Let the cake cool completely.
In a large bowl, beat together the peanut butter and softened butter until smooth and creamy.
Add powdered sugar, milk, and vanilla. Beat until fluffy. Add a bit more milk if the frosting is too thick.
Spread the peanut butter frosting over the cooled cake.
Warm the extra 1/4 cup of jelly and drizzle over the frosting. Use a knife or toothpick to swirl if desired.
Sprinkle with crushed peanuts or chopped peanut butter cups if using.
Chill for 30 minutes to set, or serve immediately.
You can use grape jelly if you prefer the classic PB&J combo.
This cake tastes even better the next day once the flavors meld together.
