These easy Blackberry Oatmeal Crumble Bars are made with only four ingredients and are seriously delicious. We like to eat them warm with ice cream but they are equally yummy at room temperature. Easy bars are LIFE. Try these favorites too: Irresistible Key Lime Pie Bars, Heavenly Hash Truffle Bars, and Lemon Drop Bars.
Blackberry Oatmeal Crumble Bars
A couple of weeks ago my Dad and brother came over to install a ceiling fan in our patio. Summers are crazy hot here in Sacramento and this fan is going to make the patio a much more comfortable place to hang out. I asked my Dad if he had any requests for snacks or treats while he was working and he said, “Oh anything would be fine” which I understood as, “You better make me something good!”
It dawned on me that I hadn’t made any of my mom’s oatmeal crumble bars in a long while and I knew they would be perfect to snack on during the day. I grew up on these bars. I started making them when I was about 8 years old and haven’t stopped since. They are SO, SO, SO easy and you are not going to believe how yummy they are! The crumble portion of the bars is made with yellow cake mix, oatmeal, and butter. That’s it. And it’s divine.
I love recipes like this that are so easy and taste like a million bucks. This crumble bars recipe is a great recipe to have your kids help out with. There are no eggs involved and the steps are so simple there’s really no way to mess it up. I will forewarn you that the crumble mixture is completely and totally addicting. The only way I can keep from snacking on it is because I know it tastes even better after they’re done 🙂
Speaking of after the bars are baked…now is a good time to enjoy the bars. We do – with a spoon! Straight from the oven the bars are just heavenly. If you think of it – spoon some into a bowl and top it with a scoop of vanilla ice cream. Then you can come back and thank me. It’s incredible! I’m slightly embarrassed to say that close to half of the 9 x 13 baking dish was eating via spoon. The good news? We still had half to cut into bars the following day!

Joyce says
I would love to kno how to make these with real blueberries
Trish - Mom On Timeout says
You would basically need to make a blueberry pie filling with them Joyce. It needs to be pretty thick for this recipe. Good luck!
Lauren @momhomeguide says
A neighbor of mine made raspberry oatmeal crumble bars recently, and I think it was a similar recipe. They were gone very quickly — so good! I might just have to make these TOMORROW!! (Forget the diet!)
