Peanut Butter Explosion Chocolate Cake (1)

I wanted to stop in todayand let you know how my journey with P90X is going.We are half way through week 2, sowoo hoo only 10 more weeks to go!

Uuuugggg!Doesn't sound as exciting that way, does it?Let's stick with HALFWAY through week 2!!!

I would much rather be sleeping in and baking my way through cupcakes and brownies instead. But I guess that's what got me into this predicament in the first place. Late night snacking on Mocha Fudge Cupcakes and Reese's Popcorn has come back to bite me on the big butt!

Some things that I have discovered while working out with these videos...

  • It wasn't as hard as what I was afraid of. Now don't get me wrongit is super tough, and I am panting and sweating my way through each video.
  • Yoga is for the birds. I have been doing the extra cardio video in place of it.Anyone out there that likes yoga? More power to ya! I would rather be moving.
  • New sore muscles each morning are just going to happen. Imagine the painI am feeling right now after about a billion girly push ups, and that was 2 days ago!
  • Those of you who warned me of the superman and banana. Uuuggggg is all I have to say!
  • You will actually gain weight the first week of doing this! Believe me NOT COOL!!!!I realize that it is just muscles growing, so that they can shrink, but come on already. With all the sweating going on I should have lost some right?
  • Determination is needed to keep yourself going each morning,or even just to push play each day. LOL!

Personally I would rather dive into a big slice of this yummy Peanut Butter Explosion Chocolate Cake. But it's probably not in the P90x diet guide.

So if you make this cake,remember me and my sugar deprived bodywhile you are enjoying it!

I was looking through some old pics and realized that I nevershared this chocolate cake from my birthday.Yes, I made my own cake if you were wondering.Believe me it is better that way!My hubby handles dinner, and I do all the baking!We work well together!!!

Plus, I knew exactly what I wanted in it,and I like doing it! Box cake mix hacks are some of my favorite things to do in the kitchen. I like to pretend I'm a cake mix doctor and create new and improved desserts from box mixes!

If you don't like peanut butter,you probably should stop reading right now.This cake is not for you! You may enjoy this Strawberry Mousse Cake instead.

How to make a Peanut Butter Explosion Chocolate Cake:

  • Make two chocolate cake mixes following the package directions. Stir a bag of mini Reese's peanut butter cups into the batter.
  • Grease and "flour" 2 - 10x2 inch round cake pans with cocoa powder. Cocoa powder dissolves into the batter, so you don't have a white ring when it comes out of the pan.
  • Divide the batter evenly into the two pans and bake for 28 minutes. All ovens bake differently, so make sure to test it with a toothpick or knife to see if it is done.
  • Let the cakes cool completely, then cut each cake in half horizontally.
  • Fill the cake layers with the Best Honey Peanut Butter Frosting. Make sure to reserve at least ¼ cup frosting for the top decorations.
  • Cover the top and sides with Dark Chocolate Buttercream Frosting. You can use a cake decorating tool to make the grooves on the sides of the cake. Or you can use a fork and just drag it through lightly all around the entire cake.
  • Use a piping bag and icing tip 21 to swirl the reserved peanut butter frosting on top. Add peanut butter cups to the swirls.

Peanut Butter Explosion Chocolate Cake

Yield: 1 - 10 inch cake

Prep Time: 30 minutes

Cook Time: 28 minutes

Total Time: 58 minutes

The layers of frosting and peanut butter cup candies in this Peanut Butter Explosion Chocolate Cake will impress everyone at dessert. It's the perfect cake to make for parties or bake sales.

Ingredients

  • 2 chocolate cake mixes
  • 1 bag of the Reese's Mini Peanut Butter Cups
  • 1 batch Best Honey Peanut Butter Frosting
  • 1 batch Dark Chocolate Buttercream Frosting
  • 7-8 Reese's miniature Peanut Butter Cups

Instructions

  1. Preheat oven to 350°. Grease and flour 2 - 10x2 inch round cake pans.
  2. Mix up the two cake mixes following the package directions. Stir in the bag of mini Reese's. Pour the batter evenly into the prepared pans.
  3. Place the cake pans in the oven and bake for 28 minutes, or until a toothpick or knife inserted in the center comes out with just a few crumbs on it.
  4. Remove from the oven and let cool in the pan for 15 minutes. Flip the cake out onto a wire rack to cool completely.
  5. After each layer has cooled completely, cut each one in half.
  6. Reserve ¼ cup of the peanut butter frosting for later. Divide the frosting evenly into 3 bowls.
  7. Place one cake layer on a plate and cover it with one bowl of frosting. Repeat with the rest of the cake layers and frosting.
  8. Cover the outside and top of the cake with the chocolate frosting. (I used a fun frosting comb tool on the sides, but fork prongs would work too.)
  9. Use the reserved peanut butter frosting to pipe some swirls on top and accent with the extra peanut butter cups. Store in a sealed container on the counter.

Notes

*Make sure your cake pan is 2 inches tall, so the batter does not overflow into your oven.

    Does this cake really not have to be stored in the fridge after it’s made?

      Yes, this cake can be covered and kept on your counter for 2-3 days. If you are keeping it longer, I would refrigerate it then.

    When you say "whipping cream" do you mean like a cool whip type product or liquid whipping cream or half and half cream?

    Reply

    • Jocelyn

      It's heavy whipping cream. I must have forgot to type the word heavy whipping cream in the recipe card. You can also use half and half, milk, water, creamer. Basically any liquid will work, but whipping cream will give you the lightest fluffiest frosting.

    Can I use a 9" round pan?

    Reply

    • Jocelyn

      You can...but I would be very careful filling the cake pan with all the batter. As long as the batter doesn't fill it more than 3/4 of the way full, you should be ok. Also, your bake time will be a little bit longer too. I would do 30-35 minutes, and pull it when a toothpick inserted in the center comes out mostly clean.
