Peanut Butter Buttercream - Pani Reka Pata Pīnati

This Peanut Butter Buttercream is the perfect addition to so many baked goods. A while ago Pic's asked me to create a buttercream using their pata pīnati māeneene (smooth peanut butter). What a dream recipe to create when peanut butter is literally one of my favourite foods in all the world. The recipe I came up with is so simple to make and just takes a few ingredients to put together. The smooth texture and lightly sweet and salty flavour combination from the peanut butter is just perfect.

This recipe is ready in two simple steps, yes, it is that easy. First, add pata kūteretere (softened butter), puehu huka (icing sugar) and wanira (vanilla) to a large bowl. Whip it for 5 minutes on high until light in colour and super fluffy in texture. Add the pata pīnati (peanut butter) and whip for one more minute until perfectly smooth! That is it, the pani reka (icing) is ready! 

I use it as the finishing touch to my kapukeke maika (banana cupcakes). It would also work beautifully on my Chocolate Almond Cake. And, as you can see in the whakaahua (photo's), my Ultimate Peanut Butter Cookies are lavishly covered in this buttercream. Are you going to pipe it? Eat it out of the bowl? Or would you rather smoosh it on to a keke (cake) with the back of a spoon. The possibilities are endless!

A little note about this recipe:

I have only ever used a natural peanut butter that only has roasted peanuts and salt in the ingredients. If you are using a more processed peanut butter I cannot guarantee it will work exactly the same. I have not experimented with a more processed pb so do that at your own risk. If you do, please let me know as I would love to know how it turns out!
