Peanut Butter Cupcakes with Salted Caramel Frosting

Print This Recipe Print This Recipe

If there are only two flavors I could enjoy for the rest of my life, it would be salted caramel and peanut butter. I have a go-to peanut butter cupcake and a go-to salted caramel frosting. I’ve never combined the two before, but I knew they would be an unbeatable pair!

I’ve been making these peanut butter cupcakes for years. They are unbelievably soft and moist, which is in part because of the brown sugar and 2 eggs in the batter. They are loaded with peanut butter flavor too. The frosting is legendary. It’s thick and tastes identical to salty caramel corn, but in creamy dreamy frosting form.

I adorned the finished cupcakes with green sprinkles, perfect for St. Patrick’s Day!

Ingredients

Peanut Butter Cupcakes with Salted Caramel Frosting ingredients

For the cupcakes

1 and 1/4 cup all-purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
1/2 cup (1 stick) butter
1/2 cup Smooth Operator peanut butter
3/4 cup light brown sugar
2 large eggs
1/2 teaspoon vanilla extract
3 tablespoons milk

For the frosting

1/2 cup (1 stick) salted butter
1 cup dark brown sugar
1/3 cup heavy cream
1/2 teaspoon salt
3-4 cups powdered sugar, sifted
3/4 cup light brown sugar
additional pinch of salt, as needed
green sprinkles

Directions

1. Preheat oven to 350°F. Line 12-cup muffin tin with liners. Set aside.

2. Mix together the flour, baking powder, and salt. Set aside.

3. With a handheld or stand mixer, cream together the peanut butter, butter, and brown sugar until light and fluffy. Beat in the eggs, one at a time, then stir in vanilla.

4. Beat in the flour mixture alternately with the milk, mixing until just combined. Do not overmix.

5. Divide batter evenly between 12 cupcake tins. Bake for 23-26 minutes or until toothpick inserted in the middle of a cupcake comes out clean. Allow cupcakes to cool.

6. While the cupcakes are cooling, melt the butter in a small saucepan. Once melted, add brown sugar and heavy cream. Stir constantly over medium heat until sugar is dissolved. Add salt.

7. Allow to bubble for 3 full minutes, no more. Remove from heat and allow to cool to room temperature, about 30 minutes. Do not place in the refrigerator to cool. With a hand mixer at medium speed, beat in powdered sugar 1 cup at a time, until you reach desired consistency. I used 4 cups. Add more salt if the frosting tastes too sweet.

    I’ve been following Sally’s blog for a little while now and I’ve made a few of her recipes and they’ve all been great! As a fellow peanut butter lover, I’m looking forward to trying more (possibly starting with these cupcakes). The only downside is I’m pretty much the only PB lover in my house so I end up eating all of the goodies. I’m also in the process of trying to come up with my own peanut butter recipes. I bought some raw peanuts from a local farmers market so I can roast them fresh before grinding them up in my food processor. BTW, your White Chocolate Wonderful is by far my favorite!

    Peanut Butter Rice Krispies =) Just add about a 1/2 cup (or more, depending on how much you love peanut butter ; ) to your favorite Rice Krispies Treats Recipe. Cutting them out with Shamrock cookie cutters makes them more festive. I also like to add some shamrock sprinkles or chocolate chips for some extra deliciousness!!

    Happy St. Patrick’s Day! =)
