Peanut Butter Brownies with Peanut Butter Fudge Icing
This peanut butter brownies recipe is guaranteed to knock the socks off all peanut butter fans. The moist peanut butter brownies are topped with the most decadent peanut butter fudge icing.
My Starbucks friends have been waiting on this fudgy peanut butter brownies recipe. After a weekend of doing pretty much nothing but baking brownies, I left a message on Facebook for some folks to meet me there to share in the bounteous offerings and was able to unload these puppies with no problem at all. If you’re looking at that photo up there, I bet you can see why!
A lot of people have never had a peanut butter brownie. We’ve had fudge (of course!) and blondies but never the peanut butter ones. When I came across this recipe, I knew I’d have to make them this week! Of course, my grandmother’s peanut butter fudge icing had to be in on the baking as well and the combination of the two turned out an absolutely drop-dead peanut butter brownie recipe!
Peanut butter lovers are going to enjoy every bite of this sweet, moist, rich, and fudgy brownie. I can’t wait for you to dig in!
Recipe Ingredients
Peanut butter brownies
- All-purpose flour
- Baking powder
- Salt
- Creamy peanut butter
- Unsalted butter, softened (I use margarine)
- Sugar
- Brown sugar
- Eggs
- Vanilla extract
Peanut butter fudge icing
- Sugar
- Vegetable shortening (I usually use coconut oil these days. If you buy refined coconut oil there is no coconut taste).
- Peanut butter
- Milk
- Butter
- Vanilla
In a large bowl, add the peanut butter and butter.
Next, add your sugars to the .
Whip all that up.
It will look like this.
The instructions say to add eggs one at a time. Sometimes I add them all at once.
Welcome to life on the edge!
In a separate bowl, place the flour and baking powder and combine it with the brownie batter.
Now we need to add our flour in. Once again the recipe states to gradually do this. I absolutely agree that you should gradually add your flour in when the recipe says to do it.
Just don’t expect me to do it. Here at Southern Plate, we’re busy folks. We wanna eat our food, not build a shrine to it. Just dump it all in and it’ll be fine.
Add the vanilla to the brownie batter and mix well.
Spray a pan with cooking spray. Spread your batter into the prepared pan.
You should have a good bit of brownie mix unless you ate some of it back there!
Bake at 350 for 30-35 minutes.
Then let your peanut butter brownies cool while you make the peanut butter frosting.
How to Make Peanut Butter Fudge Icing
In a heavy saucepot, add the sugar, shortening, butter, milk, and a wee bit of salt.
Stir that up while bringing it to a boil. Continue stirring this so your sugar doesn’t scorch.
There, now that we have it at a full rolling boil. Stop stirring and set your timer for two minutes.
After two minutes, take it off the eye (or stovetop for our friends up north) and stir in your peanut butter and vanilla extract.
Mix that well. Be quick about it because it will start setting up rather soon.
Pour over brownies.
I sprinkled the top of my peanut butter brownies with salted, roasted peanuts and the salty flavor was just wonderful with the sweetness of the brownies and the icing!
Slice them brownies now!
Please be careful not to drool on your keyboard. If you short it out I won’t be buying you a new one.
Storage

- You can also freeze your peanut butter brownies for up to 3 months. Tightly wrap individual portions and then thaw overnight before indulging.
Recipe Notes
While the generic grocery store creamy peanut butter works best in this recipe, if you want to use natural peanut butter, make sure it’s very well stirred before you add it in. I don’t recommend or substituting for a different .

I really like the layout of the recipe itself. listing the ingredients with the instructions is genius! So much easier to follow.

So glad you love it!
I’ll eat just about anything peanut butter. I can’t wait to try these. But I wonder, can I cut the sugar down to 1 cup?
Two of my favorite things, peanut butter and brownies!
Can’t wait to try these.
This is definitely a recipe I will be using . My family loves anything peanut butter
Christy, I’m moving you into the lofty realms of Southern Living and Betty Sims (cookbook author in Decatur): Your recipes don’t have to be tried first at home to make sure they work. Good stuff always.
I made these yesterday. Normally I’ll double an icing recipe just to make sure there’s plenty. This time I made the recipe as written using an 8×8 pan. The icing was easily 1/2 inch thick. Next time I may double the brownie layer and keep the icing as is. They were FABULOUS. I didn’t have milk, I used half and half and butter. The icing is like soft fudge or caramel.
I am so glad you liked them Phyllis!! Yes, it does make plenty of icing even for an 8 X 10 or a 9 X 11.
