Making Oatmeal Cookies is always a treat. They are chewy and sweet with a little crisp bite. Yum.
But what happens when we turn one of these Cookie Packages into a decantant dessert? Well let me tell you.
YUM!
You can fool just about everyone with this desert especially if you take the time to dress up the plate, serve with a chilled glass of milk.

Just make sure you throw away the Oatmeal Cookie Package, okay?
What's in Lemon Oatmeal Bars?
- 1 pkg Oatmeal Cookie Mix
- ½ Cup Butter
- 1 Egg
- Sweetened Condensed Milk
- ¼ Cup Lemon Juice
- 1 teaspoon Lemon Zest
I like to use cold butter in this recipe and use a cheese grater to grate bits of butter into the Oatmeal mix. Trust me. Genius!

How to make Lemon Oatmeal Bars?
- Use a large bowl and add cookie mix with cold grated butter.
- Mix with a fork to make crumbles
- But it doesn't hurt towards the end to get messy and use your hands
- With a fork add 1 egg and combine. The mixture will get a little sticky at this point but also crumbly too. It's a strange mixture, but it works.
- Spray an 8x8 or 9x9 glass pan with cooking spray and place half the cookie mixture in the bottom of the pan.
- Use a fork or your fingers to spread evenly to make a crust.
- Bake at 350 for 12 minutes.
- In a separate bowl combine sweetened condensed milk, lemon juice and lemon zest.
- With a spoon stir until fully combined. Mixture will be a thick pudding like consistency.
- Pour mixture over baked crust and crumble remaining cookie on top
- Bake for 22-24 minutes or until golden brown
- Allow to cool for at least 30 minutes before cutting.
- Store in refrigerator
Betty Crocker Lemon Oatmeal Bars are decadent. Sweet Rich Lemon flavored bar cookie with an oatmeal crust.
I hope your mouth is watering, because I truly love these sweet bars

How to store Lemon Oat Bars
Because this recipe has sweetened condensed milk, it's best to store in the refrigerator. Personally I love a cold Lemon Bar
Can I double the batch?
Of course you can, just double the ingredients of course! 😉

This is a recipe my mother would have me make growing up because it was a perfectly easy recipe that I couldn't mess up.
Funny thing is, this is a recipe I started my own boys with. With few ingredients and even less to measure its a great recipe to teach a little.
Plus, you can do it all by hand. No hand mixer involved.
Lemon Oatmeal Bars have an oatmeal base with a lemon filling and then cookie crumble on top. The Flavors are perfectly blanaced.
So go ahead and pour yourself a glass of milk and sneak a bar or two and enjoy!
