Welcome to one of the most addicting things you will ever eat, I never thought I could outdo brown butter rice Krispies, in fact when I made these I was ready to give the whole tray away. Then I tasted them. Then I almost fell to the floor with sheer love for these peanut butter rice krispies.

The peanut butter against the marshmallow is just about perfect. The peanut butter also helps make them not overly sweet. Aka you can eat 15 pieces and feel fabulous.

I like a really soft, extra marshmallow gooey rice krispy treat, the last thing I want is a hard one that is hard to bite into.

So this recipe calls for more butter and marshmallows then most other recipes. But it's so worth it.

Let's get to the recipe.

Before it has completely combined add the remaining marshmallows.

Continue mixing until every rice cereal is coated, you will still have chunks of marshmallows- thanks to the ones you just added. Pour into the prepared pan.

I use the back of a spatula to gently press down evenly to an even layer.

Can you make Peanut Butter Rice Krispies ahead of time

If you are serving them the next day I prefer to cut that next day. Keeps them fresher. Store in an airtight container for a few days, but they probably won't last that long. These are my favorite plastic containers.
