One-Bowl Ooey Gooey Peanut Butter Chip Blondies

Total Time
Prep 10 mins
Cook 25 mins

This one's for the "undercooked cookies are the best" crowd. Well, I suppose I'll allow you to cook them all the way if you like. :) I've tweaked this recipe a bit to get it to the point that it's no fuss, and can even be done in one bowl. No messy scooping around in the peanut butter jar; this one uses peanut butter chips instead. You can substitute other types of chips if you like - chocolate, white chocolate, butterscotch, etc.

Ingredients Nutrition


  1. In a large microwave-safe bowl, heat margarine or butter in the microwave on half-power until mostly melted.
  2. With a wire whisk, mix in brown sugar. Beat in eggs and vanilla extract.
  3. Dump in flour, baking soda and salt (if you're a purist, you can mix them in a separate bowl ahead of time, but I've always had just as good of results with the single-bowl method). Stir with a large wooden or plastic spoon until flour is completely incorporated.
  4. Add peanut butter chips and stir.
  5. Pour batter into a greased 13x9-inch pan and bake at 350 for 20-25 minutes or until it's nicely browned and looks set.
  6. Meanwhile, eat any remaining batter sticking to the bowl. :).
  7. If you like your blondies more done, you can bake them a bit longer until a toothpick inserted in the center comes out clean. I have no idea how long that takes because I've never gone that far. I find they're just right at about 22 minutes, and definitely best when warm.

Awesome Blondies! This is one of the tastier blondies I've had, and I'm pretty sure it's the combination of almond extract and peanut butter chips. Really nice combination, and it was east to make.

I've been using recipes from this site for years. This is the first time I've felt compelled to rate a recipe! I've always wanted to make the perfect chewy blondie ~ this recipe fits the bill, and then some! One bowl? Yes! Quick? Yes! Absolutely delicious? YES!! Drizzled some chocolate over mine, but they are perfect as the recipe stands. And yes, 22 minutes is perfect!!! Thanks for sharing, ItalianMama! :)
