This Really Is The Best Homemade Peanut Butter Frosting!
I love my cookies, and I have so much fun with my cupcakes, but it’s my frosting that’s ON POINT! Sure, a good cake is important, but it’s the frosting that MAKES it.
I’ve learned that a killer frosting can save the day and that it can turn a boring box mix into something AWESOME!
This is the best peanut butter frosting around; it’s so creamy and smooth with the perfect balance of sugar and peanut butter.
What You’ll Need For Peanut Butter Frosting Recipe
Unsalted Butter – You want to use unsalted when it comes to most dessert recipes, but especially in this one since the peanut butter itself has a lot of saltiness, and we don’t want this frosting to be overly salty.
It’s also very important that the butter is at room temperature; you should be able to press the back of a spoon easily into the butter.
Peanut Butter – You obviously can’t make peanut butter frosting without peanut butter. You will want to use creamy peanut butter. I personally prefer Jif.
Powdered Sugar – You’ve got to lighten up the salty peanut butter with something sweet and powdered sugar is just the way to do it. Make sure your powdered sugar isn’t old and hard. You need it to be fine and fluffy, so sift it first if you need to.
Vanilla Extract – Vanilla is such an essential ingredient in the kitchen and especially in frostings. It helps to add a great depth of richness to almost any recipe! Make sure to use a quality vanilla or make your own at home.
Heavy Cream – While this is the best cream form to use, it’s my understanding that it can be hard to find in some parts of the country. In this case, whipping cream will do just fine.
What we’re really after is that thick, rich, creamy component that milk and water just don’t provide.
Using heavy or whipping cream during the mixing process yields a light and fluffy frosting everyone is sure to go crazy for!
This frosting recipe is simple, but it’s important that you follow my tips so that you get delicious and fluffy results!
For mixing, I find it best to make this frosting in a stand mixer with a paddle attachment (but a whisk attachment is fine too).
The high power can whip this recipe into the fluffy gloriousness that makes it so great. In a pinch, a hand mixer will do just fine!
How To Make Peanut Butter Frosting
- Cream together the butter and peanut butter until smooth.
- Add the powdered sugar a cup at a time, alternating with the heavy cream.
- Add in the vanilla and whip at high speed for a few minutes until light and fluffy.
I Make This Frosting A Lot! Sometimes, I just eat it straight because it’s peanut butter awesomeness! So I’ve had a lot of practice and have a lot of troubleshooting tips!
How To Store Fluffy Peanut Butter Frosting
This frosting is considered safe in an airtight container at room temperature for two to three days.
Does It Need To Be Refrigerated?
Because the small amount of heavy cream is stabilized by the amount of confectioner’s sugar in the recipe, it does not need to be refrigerated. However, it will last for up to a week in the refrigerator.
Can you freeze frosting?
Yes, I recommend storing it in an airtight container for up to 3 months, letting it thaw at room temperature, and then beating it to remix. I don’t recommend storing it in a freezer bag because it will be much harder to remove and result in a lot of waste.
Peanut Butter Frosting Buttercream FAQs
Did you use Natural Peanut Butter? This is usually the most common reason. Peanut butter that has been sitting for a long time and has separated will cause an oily frosting. I prefer to use JIF creamy peanut butter, and I find it gives the best flavor and texture.
I wouldn’t recommend it, especially if you plan on piping the frosting onto a dessert. Stick with creamy for the best results!
This Peanut Butter Frosting Recipe makes about 8 cups. This should be enough to frost 24 cupcakes, a 9×13-inch sheet cake, a 2-layer 8 or 9-in round layer cake, or fill 12 whoopie pies.
Grainy frosting is usually the result of using really clumpy powdered sugar. If you find that your powdered sugar is clumped, I recommend sifting it before using it. It’s also less likely to be grainy when mixed with a paddle attachment in a stand mixer bowl.
Usually, separation is a result of the butter’s temperature. You want to make sure that your butter is really soft but not melting.
Another possibility is the oil in the peanut butter; I find separation is more likely with all-natural peanut butter.
No, the butter should be at room temperature and pretty soft. Preferably having sat at room temperature for at least a few hours before using.
For thicker frosting, you can add more powdered sugar. For fluffier frosting, add a bit more heavy cream and whip at high speed for an additional minute or two.
