The Best Chocolate Peanut Butter Cake has layers of chocolate and peanut butter frosting and is decorated with Reese’s peanut butter cups. It is the perfect dessert for chocolate lover’s.

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 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 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.  
4. Bake the chocolate cake batter in a 9×13 pan that has been greased very well.  
5. Let the chocolate cake cool for 15 minutes in the pan, then flip it out on a wire rack to cool completely.

BRUCREW TIP: The coffee in the batter just enhances the chocolate flavor.  You will not taste coffee in this cake, but if you are opposed to it, use water instead.

How to assemble a Chocolate Layer 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 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 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 Chocolate Peanut Butter Cake for the price of one cake slice.  I’d say that is winning at dessert!
