Chocolate birthday cake with creamy chocolate frosting and a sweet peanut butter glaze. A chocolate and peanut butter lovers dream!

I’m not sure I’ve ever been so excited to eat a chocolate birthday cake before. Chocolate cake, chocolate frosting, peanut butter glaze YES PLEASE. Both my husband and I are chocolate + peanut butter lovers (especially my husband!) so it made perfect sense that he asked for a chocolate cake with some sort of peanut butter element added in for his most recent birthday. Being the baking enthusiast and food lover that I am happily obliged.

I didn’t take step by step photos because KIDS (and I baked the cake portion at 11pm the night before) but I assure you the hardest part of this cake is frosting it…and even if you don’t frost it perfectly, never fear! That’s what peanut butter glaze is for!

I used my Perfect Chocolate Cake Recipe as the base, my Chocolate Frosting recipe to fill and coat and then a basic peanut butter glaze (four ingredients!) to drizzle down the sides and spread evenly over the top (which is listed below).  Of course if you have a recipe for chocolate cake or chocolate frosting, by all means use that! Heck, use a cake mix and a can of frosting for all I care! Do what you know and what you think tastes good. If you ARE going to use a can of frosting though, make sure you whip it a minute or two with a hand mixer to lighten it up and make it easier to spread. It’ll make a world of difference.

My pro tips for this recipe would include:

  • cooling your cake completely before attempting to frost
  • whipping your frosting so it’s completely smooth and easy to spread
  • Adding too much frosting at first to make spreading easier (with less crumbs!) using an offset spatula (best tool ever for frosting cakes!)
  • Taking off all that extra frosting off as you go to get a smooth and professional finish
  • using a teaspoon to add the drips down the sides of the cake

Below are a few more photos and then the printable recipe at the bottom.

Have a great day, friends!

    Lauren! This is perfect! I have been hunting for a good cake recipe for my boyfriends birthday coming up on October 11th, and this one will probably be my pick! He absolutely loves peanut butter, and asked for a chocolate cake- so, yes please!
