A small square of these rich bars is enough to satisfy a dessert craving. The flour and oats mixture is somewhat dry after combining, but it serves as both a solid base for the soft butterscotch chip layer and a crumbly, streusel-like topping.

How to Make It

Step 1

Preheat oven to 350°.

Step 2

Combine sugar and butter in a large bowl. Stir in vanilla and egg. Weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour, oats, 1/2 teaspoon salt, and baking soda in a bowl. Add oat mixture to sugar mixture; stir with a fork until combined (mixture will be crumbly). Place 3 cups oat mixture into the bottom of a 13 x 9-inch baking pan coated with cooking spray; press into bottom of pan. Set aside.

Step 3

Place sweetened condensed milk, butterscotch morsels, and 1/8 teaspoon salt in a microwave-safe bowl; microwave at HIGH 1 minute or until butterscotch morsels melt, stirring every 20 seconds. Stir in walnuts. Scrape mixture into pan, spreading evenly over crust. Sprinkle evenly with remaining oat mixture, gently pressing into butterscotch mixture. Bake at 350° for 30 minutes or until the topping is golden brown. Place pan on a cooling rack; run a knife around outside edge. Cool completely.

These bars are delicious!! They really hit the spot, they are very sweet but the crumbly base and topping even out the sweet. I have made these with walnuts in the crust and then just omitted the walnuts all together becuase I feel they are unnecessary and normally do not keep a big variety of nuts in the cupboard. They are crumbly, as noted by other reviews, however they are perfect for us!

This recipe did not look like the picture for some reason. It was a little dry for me but was still very well received. Maybe I cooked it a bit too long.

Has promise, but the topping needs more butter or less flour or something to make it stick to the bar better.

I made these for Christmas and they were okay. Kinda heavy and wish the recipe had called for more butterscotch. Otherwise had a good hearty taste to them.

Love them, you should cut them before the cool down because the sugar will harden and make it almost impossible.

As other reviewers have stated, these were came out quite crumbly. I made these today and let them completely cool, but then they were very difficult to cut. I followed the recipe exactly except I melted mini choc chips instead of butterscotch. Yummy! Next time, I will cut back on flour/oats and bake them in a smaller pan to make them chewier.

The only thing that could possibly be light about theses bars would be their size. I am not happy about the crumblyness of them though, other than that they are great,

This butterscotch bar did not taste like it was low in calories at all! My husband & I have to watch our weight, but we like a good dessert every once in a while. Now I feel like we can have it more often with these little slices of heaven.
