  • Yield: Makes about 2 1/2 dozen
Peanut Butter Cookie Cupcakes

Source: Martha Stewart Living, January 2006


  • 1 3/4 cups all-purpose flour
  • 3/4 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon baking soda
  • 3/4 cup (1 1/2 sticks) unsalted butter, softened
  • 1 1/3 cups sugar
  • 2/3 cup natural, creamy peanut butter
  • 3 large eggs
  • 1/2 teaspoon pure vanilla extract
  • 1/2 cup sour cream
  • 12 ounces cream cheese, room temperature
  • 1 1/2 cups confectioners' sugar, plus more for decorating
  • 3 tablespoons unsalted butter, softened
  • 1 1/2 cups creamy peanut butter


  1. Preheat oven to 375 degrees. Line 3 standard 12-cup muffin tins with paper liners.

  2. Make the cupcakes: Whisk flour, baking powder, salt, and baking soda in a medium bowl. Put butter and sugar into the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until pale and fluffy. Reduce speed to low. Mix in peanut butter. Mix in eggs, 1 at a time, and vanilla. Add flour mixture; mix until combined. Mix in sour cream.

  3. Spoon scant 3 tablespoons batter into each muffin cup. Bake until pale golden and a cake tester inserted into centers comes out clean, about 13 minutes. Transfer to wire racks; let cool completely.

  4. Make the frosting: Put cream cheese, confectioners' sugar, and butter into the clean bowl of a mixer fitted with the clean paddle attachment; mix on medium- high speed until pale and fluffy. Stir in peanut butter with a rubber spatula.

  5. Spread 1 1/2 tablespoons frosting onto each cupcake. Refrigerate until frosting is firm, about 10 minutes. Using tines of a fork dipped in confectioners' sugar, score each top in a crosshatch pattern. Cupcakes can be refrigerated in single layers in airtight containers up to 2 days.

    I LOVE THESE! this is a definite must for peanut butter lovers! I recommend piping a little ganache into the center of the cupcake before the peanut butter frosting. And I piped the peanut butter frosting onto the cupcakes as well. Also, these are much better right out of the fridge, so chill the cupcakes until ready to eat. I followed the recipe to a T. and it was perfect! have eaten 4 already today!

    added mini chocolate chips and my family said this made the recipe - as i didn't use frosting. baked in mini cupcake tin, just reducing baking temp.

    I just finished making these and they turned out pretty good! I think they are great if you are someone who LOVES peanut butter. I think the icing could of used a little less peanut butter in it. The cake wasn't too dry, but if you read the recipe title, these are Peanut Butter COOKIE cupcakes, which they did remind me somewhat of a pb cookie. Make sure to use NATURAL pb too, that works great! And mine only took about 17 minutes to bake and I only got 2 dozen out of the recipe as well.

    I was reading the comments and came across the one where instead of cream cheese fluff was used? How did you make frosting with that? It's very sticky?

  • kufishy 2 Sep, 2008

    Everyone says they are so great because they haven't tried making them yet. I followed this recipe to a T as well. I make a LOT of cupcakes and thought only a mini cupcake would cook that fast. I cook everything using my convection setting on the oven so it should have cooked faster. Instead it was 23 minutes! Maybe my oven is off, but not that much! The recipe also only made 2 dozen for me.
    My testers (my husband) tried it before putting them in the fridge and loved it.

    I followed the recipe to a T. I don't know what everyone finds great about these. The "cupcake" is not that flavorful, and somewhat dry, and the cream cheese in the frosting does not marry well with peanut butter in taste at all. The frosting sticks to the roof of your mouth - everyone said that. I'm thinking that the 12 oz of cream cheese might be a mistake. That's a lot of cream cheese for 1 1/2 c of powdered sugar. Cute idea, but the recipe needs a lot of work. Going into the trash can with this o

    emilybanco, loislane1947, 1toffy,

    Thanks for answering my unsalted questions! I feel empowered now.

  • MardiMayo 1 Sep, 2008

    We like these with marshmallow fluff on top for that FlufferNutter taste!

  • 1Toffy 1 Sep, 2008

    I do a lot of baking and rarely have used unsalted butter. When I did buy it for a recipe I didn't notice any difference at all. Unless you are controlling the salt intake then I dont see the difference.

  • loislane1947 31 Aug, 2008

    I have never used unsalted butter in a recipe. We don't buy it, because it's only used for baking. Everything has always come out fine.

  • emilybanco 31 Aug, 2008

    Hi, Jesse--The recipes call for unsalted butter and then have you add your own salt because this allows you to control the amount of salt--and, therefore, the overall taste--in the recipe. The amount of salt in salted butter varies from brand to brand, so there's no way to tell how much salt you're using unless you use unsalted butter. Hope this helps!

  • JessePiester 31 Aug, 2008

    Unsalted butter -- why? So many of these recipes call for unsalted butter, and then add salt as a separate ingredient. I don't keep unsalted butter in my fridge. What's up?

  • boedost 31 Aug, 2008

    Any idea how long to bake the cupcakes, as mini's?

  • ivahays 31 Aug, 2008

    Would love to try these using mini-muffin tins !! Has anyone done it this way yet? Also I love the idea using the chocolate.

  • sashab10 2 Jul, 2008

    For the 4th of July, I made PBJ cupcakes using the same concept as the mexican pudding cupcakes - made a [filtered word] in the center and alternated between red raspberry and blueberry jams - I covered the tops with white chocolate frosting, a smear of the jam to bring out the color and a piece of the fresh fruit and laid them on a platter - for extra fun, you can do mini-cupcakes, cover them in white and do a flag layout where the minis rest as "stars" - big hit!

  • kozz76 29 Jun, 2008

    I'm trying these with a chocolate frosting since you can't go wrong with peanut butter and chocolate together, and also with either a strawberry or raspberry frosting a la peanut butter and jelly...

  • sewing 24 May, 2008

    My family loves this recipe! I even converted it into a cake from my birthday party. It was a huge hit!

  • kamd 18 Feb, 2008

    These sound very good, but I was wondering if buttermilk could be substituted for the sour cream?

  • BoxerLover 8 Feb, 2008

    These were very dense, but really good! Everyone liked them! I would only put 1.5 tablespoons of batter into each muffin cup, to get them to look like they do here. 3 and they bloomed up like a cupcake. Either way very eatiable!
