“Peanut Butter Brownie Cups, made in muffin cups, are a year-round treat, and they’re especially convenient to take along on picnics,” says Joyce Gibson of Rhinelander, Wisconsin.
TOTAL TIME: Prep: 30 min. Bake: 15 min. + cooling YIELD:24 servings


  • 1/2 cup peanut butter

"I'm terrible at baking! The flavor is wonderful, but mine didn't turn out very well. I need something fool proof if I'm going to bake."

"Delicious! I made these for dessert for a family dinner and everyone loved them. I don't think that anyone had just one!"

"Delicious, peanut butter filling was amazing. However, the chocolate brownie part was just to dry to be very tasty to me. I think I'll use my own brownie recipe but add the peanut butter filling from this recipe."

"I found this recipe to be great! There was just enough chocolate and peanut butter taste. They were sweet, but not overly sweet. I did cut out 1/4 cup of the regular sugar though. I also used 1/2 cup of semi sweet chocolate chips instead of 3 ounces of unsweetened. 3 ounces is about equivalent to 1/2 cup. They were great, the peanut butter did sink to the bottom some but that didn't affect the taste!"

"I have made these a few times and they are very good. I have had several recipe requests for them.

They are a bit tiresome to make though. It takes quite a while to get the batter and filling portioned evenly, but it's worth the effort.
They're nice to take to potlucks & picnics because you don't have to deal with messy frosting."
