Whenever we go out to eat, I love to check out the dessert menu.  It doesn’t matter if we have been to that restaurant a thousand times before.  I am still going to sit and drool over the desserts.  

It’s like I have a thing for desserts or something. Especially if it is chocolate cake. I definitely have a weakness for that sweet goodness!

Now some times we leave room for dessert, and sometimes we walk away.  Mainly because I either ate way too much dinner, or there is some crazy dessert like this Thin Mint Cheesecake Brownie Cake or these Chocolate Lava Cakes already waiting in our kitchen at home.

But then sometimes we say no to dessert because we can’t justify the price.  Who wants to pay $9 for a slice of soft moist chocolate cake?  

Especially when I know that I can bake an entire homemade chocolate cake for that same price.

I do love a good chocolate cake, so I started looking for the best chocolate cake recipe that I could give a BruCrew twist to for my birthday. Of course, peanut butter had to be involved too.

As soon as I saw a cake that was called the Best-Ever Chocolate Cake, I knew that was the first one I was going to make and see if it was worthy of the name.  Not that I doubted it was good, but I was very curious to see if it would live up to my particular sweet tooth expectations.  

I have to admit that I have become a very, very picky dessert eater in the last few years.

It was so fun to look at the chocolate cake recipe and see what little tweaks and changes I would make based on how I like to bake.

How to make The Best Chocolate Peanut Butter Cake:

  1. Make sure to beat the butter until light and fluffy, then add the sugar and beat it again.
  2. Add the eggs and vanilla and mix it one more time.
  3. Stir together the dry ingredients in a bowl and add them alternately with the milk and coffee mixture. Trust me. You will not taste the coffee in this cake. Coffee just enhances the chocolate flavor making it more intense and delicious.
  4. Bake the chocolate cake batter in a 9×13 pan that has been greased very well.  Let it cool for 15 minutes in the pan, then flip it out on a wire rack to cool completely.

How to assemble a chocolate layered cake:

  • Make a batch of homemade chocolate frosting for the center of the cake layers. Sometimes I switch it up and use this Dark Ch0colate Buttercream Frosting. It just depends what mood I’m in.  Either one is delicious!
  • Cut the cake in half, making two 4 1/2 x 6 1/2 inch cake rectangles.  Set aside 1/2 cup of the homemade chocolate frosting, then frost the top of one of the layers with the rest of the chocolate frosting. Top it with the other cake layer.
  • Cover the entire cake with the Best Honey Peanut Butter Frosting. Use the reserved chocolate frosting to pipe a border around the top of the cake with an icing tip 21 or 27.
  • Add chopped up peanut butter cups to the top of the cake and halved peanut butter cups around the bottom.

I do have to admit that this was seriously one of the best homemade chocolate cakes I have ever tried.  In fact, it was so good that it is hands down my new go-to recipe when I want to make chocolate cake from scratch.

So, if you are looking for an impressive dessert to make, this is your cake.  It looks like a lot of work, but it really is very easy to put together.

The best part is that you will getting the entire Best Chocolate Peanut Butter Cake for the price of one cake slice.  I’d say that is winning at dessert!

    Jocelyn, this cake looks too good to be true! Everything I love mixed into one delicious dessert! The Reese’s Cups give this cake such a nice touch. I know my entire family would devour this one. Thank you for posting it.

          I have not tried baking this in 2 round pans, but I think it would work if you used two 8 inch round pans. I’m also not sure on the baking time, so I would start checking the cakes at about 28 minutes and bake until a toothpick inserted in the center comes out with just a few crumbs.

    Haha, I am so like you! ALWAYS check out the dessert menu first. You know, something on it might sound better than ordering “real food” for dinner 😉
    I love that you put Honey PB frosting on chocolate cake. Totally drooling! Pinned!

    Jocelyn, you have done it. I have had a lot of favorites on your blog, but this is going to take the cake, no pun intended. I am in LOVE. Deep, lasting love. You know I can’t stay away from anything with PB and chocolate!

    This cake looks amazing Jocelyn! I always look at the desert menu first too. I also tell myself not to eat to much because I really want desert, but guess what happens. I eat waaayy to much so I have to forgo desert. Bummer. I agree about the prices and I honestly think our homemade cakes and desserts taste way better. This looks amazing. I’d love a slice right about now. Pinned. 🙂

    So none of the stores in my area sell Dark Cocoa powder, would I be able to use regular cocoa powder as I already have that on hand?

    Reply

    • Jocelyn says

      Yes, the baking time for 8 inch or 9 inch pans would be about the same. Just bake them until when a toothpick is inserted it comes out with just a few crumbs on it.

    Do I use powdered or confectioners sugar for cake? What kind of flour? How long will this cake keep? I want to make it Thurs or Friday for a birthday party on Saturday.

      The recipe calls for sugar and brown sugar for the cake. Any time you see just sugar, it means granulated sugar. The frosting calls for powdered sugar. I also used all purpose flour for this particular cake. It should keep for a few days as long as you keep it covered. I hope you enjoy it as much as we did.

    I will be making this for my grown up son who LOVES peanut butter and chocolate together. Does it matter whether the peanut butter is old fashioned “just peanuts”? Or is something like Jif or Skippy better? Thanks for a yummy sounding recipe!

    • Jocelyn says

      I have never tried this recipe using a “peanuts only” peanut butter or a natural peanut butter. The recipe here was tested using Jif, so that is what I would recommend using. I hope you and your son enjoy the cake!

    Just made this cake last night, and the frosting tastes delicious. Haven’t tried the whole cake out yet, but will tomorrow.
    Can’t wait to try it out!
    P.S. My cake isn’t as pretty as yours, but hopefully just as tasty.
