Blackberry Oatmeal Bars

I don’t know when people stopped eating jam on the reg for breakfast. I feel like for many past decades, people always ate eggs, toast (with butter and jam) and bacon for a healthy, hearty breakfast. Now people grab a cup of coffee and go. Or they make an upscale avocado toast (which don’t get me wrong, I love)….but I am nostalgic for the simplicity of toast and jam. Which is where these bars come in.

These bars. Wow. Buttery, crunchy on the outside, deliciously smooth and gooey on the inside. These are the perfect crumbly, sticky sweet bars that will transport you back. To butter. And jam. And carbs. Aka all the good things in life.

I think the first time I made these for Benjamin is the first time he knew he loved me. Ha! They’re that good. They have such a tasty buttery crust, filled with brown sugar and rolled oats (that sounds like my love language). Inside, the filling of the blackberry jam just oozes out, getting all over your fingers but filling your heart up with so much love.

I think the thing I like most about these bars is how versatile they are. Seriously, you want to eat one for breakfast? Do it! Pair it with a creamy cup of coffee and you’re set. Or hey, you’re hungry at 2 PM? Warm that baby up and eat it as a snack! Lastly (my fave), do you have a hankering for dessert at around 9 PM after Taco Tuesday? Okay, might as well heat one up and then add a dollop of vanilla ice cream. Why not!?

The deliciousness of these bars starts with simplicity: rolled oats, flour, a little salt, brown sugar and baking powder. Super easy. Mix these babies together in a large mixing bowl.

Next involves one of my favorite things: BUTTER. The salted kind. And for this recipe, since it is the Holidays after all…involves quite a bit of it. In fact, a stick and a half. I made sure it was cold and cut it into small pieces. After that, I put all of the ingredients in my food processor so it would incorporate them together into a fine pulse of crumbs. This was the first time I had ever used my food processor for a “dough” of sorts and it saved SO MUCH TIME. I highly recommend it. If you don’t have a food processor, you can definitely mix the butter in with a fork, a pastry cutter or your ever trusty hands. Make sure you get it mixed in super well.

Also – pro tip, you HAVE to use salted butter in this recipe. It gives it just the slightest salty-sweet vibe and it’s to die for. Salted butter plus the sweetness of the brown sugar and the blackberry jam. SO MUCH YUM.

Next, make sure you grease your pan (or you can use parchment paper!) and you place half of your mixture firmly patted down in the bottom of the pan. Add a few dollops of seedless blackberry jam/preserves and spread it all over the oat mixture. Then carefully add on the other half of the mixture and gently pat it to where it sets up. Place it in the oven, bake it for around 35-40 minutes and you’re done-zo!

Now you can sit back and enjoy one (or three) of these delightful little treats. Disclaimer: Make sure to have a napkin around – these babies sure are oooey gooey and sticky. Enjoy!
