My daughter and I made these for her to take to summer camp. We added an extra egg, filled the cupcake papers 3/4 full, put the tbsp. of chocolate chips in the middle and pushed them down a little with a spoon and baked them for 24 mins. They were great; a perfect consistency!! I guess the extra egg helped! The melted chocolate chips made a nice little surprise in the center. The icing was really good too. We used cream cheese icing and added the peanut butter; also added a tsp. of milk to soften the icing a little as per Cookie Queen's suggestion. Thank you for a great recipe! Read More

I made two small changes--I used chocolate fudge cake mix in place of the brownie mix in place of the brownie mix (the reviews were mixed, I didn't want to waste ingredients since money is so tight. I apologize to those who think I radically adjusted the recipe. Sometimes, you have to go with what works.) and I used Pillsbury vanilla frosting instead of funfetti. These were easy for me to make with my two boys and they turned out really well. I have to say that I was iffy about mixing peanut butter and pre-made frosting but it works. This one's a keeper. My son says he wants this in his recipe box now. Read More

This rating is for the frosting only. I made the peanut butter cupcakes from this site (amazing) and wanted PB frosting instead of chocolate. After reading several recipes I chose this one for ease. Why make all the mess when everything you need for the frosting is already done. It was wonderful and made the cucakes taste even better than they were plain. I did add a TBS if milk to soften it a little since the cupcakes were so moist it just made it easier to spread. Awesome!!!! Read More

This will be my go to chocolate cupcake recipe. I thought something was wrong when they came out of the oven; they felt very heavy and hard but they were perfect! Dense, rich cupcake. Thank you for the recipe! Read More

This frosting is great, especially for chocolate & PB fans. You may have to experiment with the proportions a bit to find a consistency you like, but I have made these twice now and everybody loves them. I will definitely be making them again! Read More

I also added an extra egg to this recipe. They didn't rise up as much as a cupcake usually dose, however they were very yummy! The icing was great, I did add more peanut butter to suit our taste. Not our favorite cupcake, but it is yummy! Read More

These were easy and quick to make. My sister in law and I made them when we were craving some chocolate and they satisfied that craving! We followed the advice of some of the reviewers here and added an extra egg to make the cupcakes fluffier and 1/4 a cup of milk to the batter because it was REALLY thick. The frosting was very simple and easy to make and we also added a splash of milk to the frosting to make it smoother. Next time we will probably not bake them for the full time because the first batch came out a little overcooked. The second time we put them in for about 16 and it worked perfectly! We had to beat away our guys with the spatulas to keep them from eating the frosting before we had a chance to put it on the cupcakes, it is THAT good!! Read More

I just made a batch of these and since I need to make 72 for a reception on Friday I wanted do a test run. I followed the recipe on the Duncan Hines Family Size Premium Milk Chocolate box which called for 3 eggs and used a mixture of semi-sweet and dark chocolate and they turned out perfect. Allowed to cool for 10 minutes before cutting one in half to check the texture and doneness - perfection! So un-iced they are delicious - can't wait to try the icing too! Will definitely being using this one again! Read More
