Impossibly Soft And Moist Peanut Butter Layer Cake


May I present to you the one, the only cake of my dreams……….actually my all time favourite cake is this actual cake but with a different frosting ๐Ÿ˜‰ that’s another post for another time but today, right here we are going to swoon over one of the greatest creations of all time!

Peanut butter ๐Ÿ™‚ ๐Ÿ™‚

There is absolutely NOTHING that can compare with peanut butter and finding a way to incorporate it into a cake is sometimes harder said than done. Peanut butter likes to be a lil high maintenance and have a mind of it’s own so although baking with it is crazy fun, making a peanut butter cake that is perfect in both taste and texture is tricky as peanut butter can end up making a cake dry and dense. I’ve had my fair share of those right until I found this gem right here.


Super moist cake, extremely soft to the point of creamy, fluffy as a peanut butter can ever be and delicious beyond words! I swear you guys this cake is just like eating a big spoonful of peanut butter cream, it’s just THAT soft and moist!

The cake comes together so easily using basic ingredients and just your typical creaming method. I highly recommend the brown sugar as it boosts the moisture and bumps up the flavour.

Power ingredients are sour cream and milk; sour cream is mandatory, it’s what makes or breaks the cake. You can substitute with yoghurt, but just don’t leave it out.

As far as the peanut butter goes I just stirred in some good ole’ creamy peanut butter but you have to make sure that you use a good quality peanut butter. No homemade or cheap brands please. Seriously I’ve tried sooo many different variations and I’ve only ever had a great outcome using good quality peanut butter.ย 46486137_10161084474790364_984427055661711360_n

I like to make this cake smaller than normal, a nice and thick 7 inch layered cake because peanut butter is quite rich and just a small slice goes a long way especially when you’re topping it with peanut butter frosting too ๐Ÿ˜‰ you can frost with anything you like chocolate, caramel, honey, vanilla etc this cake is delicious with everything!

This is my cake, the one I make for my birthday or any occasion that needs celebrating. It is just perfect and I’m so proud of it! please get into the kitchen and make it! ๐Ÿ˜€

  5. Add in a third of the flour mix and whisk until barely combined then add in the sour cream and whisk until just combined. Add in another third of the dry ingredients followed by the milk whisking each until just combined. Add in the last third of the dry mix and whisk until *just* combined and no more flour streaks remain. Batter will be slightly thick and fairly smooth but itโ€™s okay if there are a few lumps, donโ€™t try to whisk them out.
  6. Divide batter between cake tins. Bake for 20 to 25 minutes until cooked through and a toothpick comes out with a few moist crumbs or clean. Cool on a wire rack for about 15 โ€“ 20 minutes then store in an airtight container to cool completely.
