Peanut Butter and Mascarpone Frosting

This peanut butter and mascarpone frosting is so damn good you’ll want to eat it with a spoon. Though it’s extra scrummy on a thick slice of mud cake.

Trust me, you’ll want to make this recipe asap - and then put it on repeat!

Homemade Peanut Butter Frosting With Mascarpone

You just found your new favorite frosting recipe. I’m that confident you’ll love this!

I know there are so many different types of frosting, and yes, this might not be the best when paired with lemon cake.

But still, this peanut butter and mascarpone frosting is nutty, smooth, and luxurious.

I first came across this recipe last year when I was looking to spoil my Swedish friend. She was coming to visit and has a deep love for peanut butter.

And this recipe was the perfect addition to my chocolate cake. It’s creamy, not overly sweet, and pipes like a dream!

Ingredients

Here’s what you’ll need to make it:

• Peanut Butter - of course. What else?
• Butter - to help cut through the peanut butter
• Powdered Sugar - to make it nice and fluffy
• Mascarpone Cheese - for a wonderfully rich and creamy finish

How to Make the Best Peanut Butter and Mascarpone Frosting

You can make this easily by hand, provided you’re starting with room-temperature ingredients. Soft butter is a must here, so it incorporates without leaving any bits behind.

Of course, you’re free to use a mixer or hand mixer too!

1. Whisk the peanut butter with the butter until smooth and lump free.
2. Add the powdered sugar then mix it in with a spatula so it doesn’t billow out of the bowl.
3. When it’s mostly mixed in, whisk until smooth - about 2-3 minutes. You can use an electric mixer here.
4. Add the mascarpone cheese and beat for another 2-3 minutes. 
5. Put the frosting in the fridge for at least an hour before using.

How to Use This Peanut Butter Frosting

As you can see in the picture above, I used it as a topping for a decadent mud cake. And I drizzled it with some salted caramel for good measure.

But it’s also great on:

• Brownies
• Cupcakes
• Sheet Cakes
• Layer Cakes
• Cake mix donuts

Recipe Tips

This recipe is pretty easy to make, but I do have a few tips so it’s perfect every time.

• Use creamy peanut butter, not natural - natural oil is too oily, and it’ll make the frosting oily
• Sift the powdered sugar before mixing it in - this will help to make it extra smooth
• Chill the frosting before use - between the soft butter and mascarpone, it’ll be quite soft when you’re done. So make sure to chill it before you try to pipe it
• Make it thicker with extra powdered sugar - you might need to use an electric mixer in this case
• Use this recipe to decorate a layer cake - this recipe should be enough for a standard 8-inch layer cake.
