Peanut Butter White Chocolate Cupcakes

With all the excitement I’ve had receiving entries for my Mystery Box Cupcake Challenge, I had forgotten that I wanted to post about the peanut butter cupcakes with white chocolate frosting that I had made last week!  I got the inspiration for these cupcakes when I made these peanut butter cookies and added white chocolate chunks to the cookie dough.  It was a really nice combination.  I just had to make a cupcake out of it.

Peanut butter cupcakes with white chocolate frosting and a sprinkling of white chocolate shavings!  I have to say that the peanut butter flavor really overpowers the white chocolate frosting, even though the frosting really does taste like white chocolate.  It still tastes pretty darn good though!

A note about the frosting – make it as soon as you’re ready to eat it.  It starts out nice and white, but after it sits for a few hours, it starts to turn yellowish.

And finally, keep a glass of cold milk nearby because just like straight peanut butter, these cupcakes stick to the roof of your mouth!

Peanut Butter Cupcakes
Adapted from I Heart Cuppycakes
Makes 12 cupcakes

Ingredients
1 cup all purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
6 tablespoons unsalted butter, softened
3/4 cup smooth peanut butter, room temp
1 cup brown sugar
1 egg
1 teaspoon vanilla extract
1/2 cup milk

Method
Preheat oven to 350F. Line muffin tin cupcs with paper cupcake liners

Sift flour, baking powder and salt into a medium bowl and set aside

In a large bowl, using an electric mixer on medium speed, beat the butter, peanut butter and brown sugar until smoothly blended and lightened in color, about 1 minute. Stop the mixer and scrape down the sides of the bowl as needed during mixing. Mix in egg. Add vanilla and beat for 1 minute or until batter smooth.

On low speed, add the flour mixture in 3 additions and the milk in 2 additions, beginning and ending with the flour mixture and mixing until the flour is incorporated and the batter looks smooth.

Fill each liner with a generous 1/4 cup of batter, to about 1/3 inch below the top of the liner. Bake just until the tops feel firm and are lightly browned and a toothpic inserted in the center comes out clean, about 22 minutes. There will be cracks on the top. Cool cupcakes for 10 minutes in the pan on wire rack.

    Hi – This sounds and looks absolutely delicious. I am a new follower … From NYC. I cannot seem to find the conversion of 100g of chocolate. What would that be in ounces BEFORE I melt it down? And what is sugar icing? Is that what we call here [confectioners sugar]? :(

    Hope you can help me!

  7. Mmm! I’ve paired peanut butter with white chocolate in the past for my husband who turns his nose up at regular chocolate and much prefers white. I’ll have to put your recipe to the test and see if he approves. I suspect he will!

  11. Peanut butter with white chocolate. It sounds good. I ahve never made this. I;m gong to save the recipe. Of course, you can never go wrong with peanut butter and chocolate, this is a new twist. Can’t wait to try it.

  13. Holy cow! I made these last night and am absolutely in love with the peanut butter cake recipe. It’s a winner! For a twist (and to suit my personal preferences) I made half with white chocolate buttercream and half with semi-sweet chocolate buttercream. I couldn’t wait to get up this morning and scarf down another one for breakfast. Thank you!

    • The last time I made these peanut butter cupcakes, I had put a chocolate ganache on top. I bet they’d taste great with chocolate buttercream too! I agree though, I love that peanut butter cake recipe! :)
