These are a recipe I just invented, which turned out so well I had to share. They're based off of regular chocolate chip but have different chunk content: only use 1/3 the chocolate chips, but add equal amounts of mini marshmallows and pecan bits. I made a small recipe; it can easily be doubled.
1 stick butter
3/4 cup of sugar, half brown & half white
splash of vanilla extract
1 cup of flour plus a bit
1/2 teaspoon baking powder
salt to taste if you're using unsalted butter
about 1/3 cup chocolate chips
about 1/3 cup mini marshmallows
about 1/3 cup chopped pecans
Step 1: Mix Ingredients
Butter should be soft: let it sit out for an hour or nuke it for like 5 seconds depending on your microwave. When your ingredients are all ready, preheat the oven to 350° F.
Place the soft butter in a bowl. Dump in the sugar and mash it into the butter with a spoon (or a mixer but I find that makes the dough fluffier than I like). Add egg and vanilla; mix. Add flour, baking powder, salt; mix.
Finally, dump in about a third of the amount of chocolate chips you think would be good. Add comparable amounts of mini marshmallows and chopped or broken-up pecan pieces. The last pic shows the proportions I ended up with. I might have put a bit more of each chunk in, but it was the last of the pecans and I didn't want to get all UNEVEN!
Step 2: Bake
Do the usual drop from a spoon onto a baking sheet. Bake for ten minutes at 350° F. Cool on wire rack. Eat as soon as possible, with a cold glass of milk.
