Peanut Butter Frosting
I am so excited to share this recipe with you today! Plan on baking something – a chocolate cake or cupcakes, or some fudgy brownies – so you can slather this creamy Peanut Butter frosting all over it!! ?
I’ve shared this recipe before as part of my Kit-Kat Cake post, but I felt like this recipe really needed to be in its own post. This is the MOST REQUESTED frosting recipe I have. It’s been shared at dozens and dozens and dozens of times at birthday parties, cookouts, potlucks, holiday gatherings, or just because I needed an easy dessert for company. I have been asked for this recipe countless times and I’m always happy to share it!
This Peanut Butter Frosting recipe is so easy and it comes together with a few common ingredients – butter, creamy peanut butter, powdered sugar, milk, and vanilla extract. That’s it. Although you can use a big stand mixer for this, a hand-mixer works just fine!
I won’t judge you for wanting to eat this by the spoonful, I may have done that a time or two myself! ?
