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.

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.

I didn't have the problems other reviewers had. I found the recipe straightforward and I followed it exactly. I have made these 4 times now and they have been AWESOME every time!!

I read the reviews midway in my preparation of this recipe, so I reduced the flour and oatmeal as recommended. I used regular oatmeal and (unfortunately) full-fat sweetened condensed milk since my store didn't offer the fat free type, although I doubt the flavor would have been much different. They were very sweet and I didn't have the trouble with dryness or difficulty removing from the pan as others did. These were my first butterscotch bars to eat and I just didn't enjoy them as much as I expected. I probably won't try them again.

These were delicious, but the texture was too crumbly and dry - they broke apart when removed from the pan. These would be better using an entire stick of butter, but then they wouldn't be light!

I agree there's too much oatmeal/flour and it's a bit too crumbly. Next time I'll cut back on both a bit. Also next time I'm going to underbake these a bit. Still really love anything butterscotch and may try the toffee option!

I made both these and the Jan 2000 CL butterscotch bars at the same time, and I have to say I liked these a lot better. The Jan recipe has the butterscotch chips just scattered on top, whereas these bars have a yummy butterscotch caramelly center. I made some modifications. I used regular oats and of those I was one cup short. I think this made my bars less crumbly. Next time I will probably cut down the flour by a half cup and the oats by a half cup. I also sprayed the top with crisco cooking spray. I cut them 5 x 7 in a 9 x 13 dish making 35 servings. Yes they are a fair amount of calories per serving but I thought they were a perfect bite size.

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

These are delicious! My husband asks for them all the time. The top is a bit crumbly, but I think that makes them good, and I'm pretty sure that's how they are supposed to be based on the picture in the magazine. I did not alter the recipe in any way. After a couple of days they get a little stiff, but I think that's to be expected. I will be making these again and again! Thanks Cooking Light!
