The Best Shortbread Recipe

I had this bright idea last week to make a gooey shortbread recipe. One thing lead to another in my science lab I mean kitchen and I ended up with these fabulous marshmallow topped sweetened condensed milk smothered shortbread magic bars. They are literally one of my favorite treats yet. I know I say that all of the time, but these really are to die for. Try these for yourself and let me know what you think of my magic bars!!

How To Make Shortbread

Shortbread could not be more simple. I am talking butter, sugar, flour and a pinch of salt. Love!!

This dough is buttery heaven let me just tell you.

What Is Shortbread?

Shortbread is a type of crumbly, sweet cookie which is commonly produced in Scotland, a nation with which the dessert treat has become associated. Traditionally, shortbread is made with three ingredients: butter, sugar, and flour.  These cookies are made all over the world, and often appear as a winter holiday treat in the United States. Dense, sweet, and highly rich, shortbread is adored by many consumers and bakers for its excellent and crisp flavor and ease of manufacture. It has been made since the 1700s, when butter as a cooking fat began to enter common use, especially in dairy-heavy areas like Scotland.

Another layer of mini chocolate chips please!

Top with halved large marshmallows or a layer of mini marshmallows would work just fine too.

    I made these bars today and something went wrong. I followed the recipe exactly, but when we tried to cut them, they didn’t stay together. The shortbread part of the bar just crumbled up and it was basically like a pile of chocolate chips! Wondering what I did wrong. They look and smell great, though. Wish they stayed together.

  2. This recipe sounds so good… But I have a question. I keep seeing recipes for bars, etc that call for sweetened condensed milk poured over top. I have never baked with sweetened condensed milk before. What exactly does that do (other than just keep the bars gooey wet)? And for those of us who are slightly frightened by sweetened condensed milk, will this recipe work without it (just not as gooey?)?

    These are really delicious! They’re unique, which I really like. Not your typical berry or peanut butter or caramel bar that you see everywhere (which are all awesome, don’t get me wrong! Love them. But it’s really refreshing to see something work so well that’s so different, AND so easy).

    My mom basically refuses/hates anything marshmallow, and she said these were delicious. I actually followed the recipe (for once, haha) and they’re really good as-is! I bet different kinds of chocolate would be great too, or some appearance of graham cracker…

    I only had mini marshmallows, though. And I had to cook mine closer to maybe 18 or 20 minutes for the second bake. The marshmallows still barely browned, but I didn’t want to overcook the bar. They still were perfect ^_^ Great idea and recipe!

    I made these yesterday, cut the recipe in half and put white chocolate chips into the shortbread layer and the minis on top. They were absolutely to die for. Hands down one of the best desserts/bars I’ve ever tried! The white and regular chocolate balanced sooo nicely. Maybe you can try that altered version some day! Love your recipes 😀

    I made these today. 🙂 I let them cool for a loooong (and very difficult) time like you said in the recipe and just tried them. OH. MY. GOODNESS. These are insanely delicious!!!! Highly recommend!!!!! You have an amazing talent!! Thank you so much for sharing!! 🙂

  7. Next to chocolate, shortbread is my favorite. And you just married two of my favorite things. And then added marshmallows. And then turned it into magic cookie bars. OMG. Help me, I’m dying. Love, love, love!

    Do the marshmallows not burn even if they’re in for ten minutes? I’ve put marshmallows on top of sweets before and they usually only last a minute in the oven before burning!

  9. The amount of delicious going on it that title is incredible. You know what is insane? I have no tried a magic bar! We never made them in Canada where I grew up. But, shortbread bars are my favorite so this looks like the perfect way to introduce myself! Pinned!
