This Peanut Butter Poke Cake is a huge favorite in our house and different that most peanut butter poke cake recipes. Believe it or not, I’m not a fan of peanut butter and chocolate cake together, so this cake has zero chocolate. It’s all about the peanut butter! I also refer to this cake as the Fluffernutter Cake. If you ever made Fluffernutter sandwiches when you were a kid (marshmallow creme and peanut butter), then this cake is right up your alley!

Peanut Butter Poke Cake

Ingredients for Peanut Butter Poke Cake

1 yellow cake box mix (plus the ingredients to make the cake)

1 1/2 cups  of smooth Peanut Butter

1 7 ounce jar of Marshmallow Creme (I used Kraft Jet Puffed Marshmallow Creme)

1 cup of Confectioners Sugar

1 container of Cool Whip

Cooking Directions

Make cake according to box and let it cool completely. Poke holes in the cake with a wooden spoon handle. Microwave the entire jar of marshmallow creme and 1/2 cup of peanut butter in a medium bowl.  This takes about 40 seconds. I took it out after 20 seconds and stirred it and then put it back in for another 20 seconds. Pour the warm mix over cake. Make sure it goes in the holes you made with the spoon.

Then heat 1/2 cup of peanut butter in the microwave . You want the peanut butter a bit warm and easy to mix,  about 20-30 seconds should be fine. Mix it in to the container of cool whip. Frost the cake with the cool whip mixture. For the topping, mix 1 cup of confectioners sugar and 1/2 cup of peanut butter with a fork until the mixture crumbles. Sprinkle mixture over the top of the cake.

Peanut Butter Poke Cake

This cake is best served chilled. I think it is better when the Cool Whip frosting is super cold. I suggest chilling it in the fridge for 2-3 hours before serving. This cake is great to make the day before an event and leave in the fridge over night. This cake should be refrigerated.

Another peanut butter dessert you may enjoy is our No Bake Creamy Peanut Butter Oatmeal Cookies. They are delicious!

  1. I made this cake yesterday an followed the recipe just as it called for . I was sad the way it turned out . Just as Char Harris , the fluff layer did not turn out so well . It wasn’t like concrete but was very chewy . It tasted o k but felt funny chewing it . I might try it again but not use the fluff layer . instead not make it a poke cake . Use p/n butter frosting the cool whip layer and the topping layer and maybe the strawberry jam in the middle . I’m a serious diabetic and make the deserts for my wife and the ladies she scrap books with one weekend a month . I taste a spoonful of each recipe I make when and if any of it comes home. A great recipe to build on . Thank You !!!! JOE P

  2. This sounds so good ! I would like to make the cake , let it cool then cut the cake in half and spread strawberry jam in the middle of the cake . Then make the cake following the recipe. Making it a P/B&J cake . Who doesn’t like P/N &J . What do you think ? I can’t wait to try this recipe. Thank You !!!!! Joe

    Good Morning!

    I made The Peanut Butter Poke Cake for our desert last night. My daughter and SIL joined us for dinner. I had a very difficult time cutting the cake. I actually had to use a steak knife. Then, trying to eat it with a fork was not working either. We could not get thru the peanut butter marshmallow creme layer. I did microwave the mixture for 60 seconds. 20 seconds at a time and stirring. Then I immediately spread it on the cake. It did not sink into the holes. I tried pushing it into the holes with the back of a spoon. That did not work. It started breaking up the cake. So I preceded to make the cool whip/peanut nut butter layer. I had a feeling I was in trouble. The creme mixture was not sinking into the cake and the little bit that was left in the bowl had turned to a rock. My question is-should I have microwaved the mixture until it was much thinner so it would have sunk into the cake? It was very pretty! But it was a complete fail. But it was very funny watching each other try to eat it.

      Oh gosh, I’m not sure what could have went wrong. My marshmallow cream was never hard. It comes out of the jar very fluffy and soft enough to spread, I just heat it up so it will sink in to the holes of the cake and mix with the peanut butter. I can’t imagine why yours was so hard. Maybe the marshmallow cream was bad. I’m so sorry it didn’t work out but I have to say, I laughed when you said it was funny trying to watch each other eat it. Ha! This cake comes out very soft and you can cut it with a fork so honestly, I don’t know why it didn’t work for you.

        Thank you for your reply!

        It was funny, It reminded us of the scene from Christmas Vacation when they were trying to eat the extremely dry turkey.

  4. I love your recipes! I can’t wait to make this PB Poke Cake. Love how you’ll “think outside the box” & the results are fantastic. Thank you!
