Blackberry Rhubarb Oat Crumble Bars

Blackberry Rhubarb Oat Crumb Bars

Whoaaa life! We're are hurtling forward at this point in time: back from Alaska, moving this weekend, zooming towards the wedding, two trips to Oregon BEFORE the wedding — it's going to be a busy 7 weeks!

While I did such a fabulous job (pat myself on the back) of planning ahead for our Alaska trip, and had posts schedule to keep you entertained while I was away, I've been oh-so-lazy while I've been back. In reality, I just can't switch my sleep schedule, so I'm sleeping 4am-1pm every day (WHAT!?). Yeah, I wish it weren't true. Needless to say, I'm feeling like nothing is getting done during a week where EVERYTHING NEEDS TO GET DONE!

Luckily, my mama flies in this afternoon (yaay!) to help us pack/move/wedding-plan, we have tons of friends who have generously offered to help us during the big push (furniture, ugh). I figured y'all could use something to tide you over, since I probably won't be checking in here until at least Tuesday next week. These bars, though, are worth it. I'm certain you can entertain yourself for at least a week with these.

I made these multiple times in a 48-hour timespan. Derek practically inhaled them. I guess I did too, honestly. I first made them without oats, then with oats, with white sugar, then with brown sugar, etc. I had a really hard time photographing any of it. Hmph. Trust me when I say, these are freaking delicious. I think the best thing I've made all year. Gotta share them before rhubarb season is too far gone (perhaps the rest of the country forgot about rhubarb a month ago, but it's just not flourishing here!).

I based these bars on a recipe I've seen a number of places, but mainly from Deb at Smitten Kitchen. Obviously I changed a few things. I like more of a solid base, so I put ⅔ (opposed to ½) of the crust mixture on the bottom. Then I added oats to the remaining ⅓, and used that on top. I also used a LOT of fruit. SO DELICIOUS. I think it's pretty hard to mess this recipe up, so just play around and do whatever seems right to you!

    Found the crust to have a lovely texture, but it would be improved by the addition of some spices and vanilla. Tasted floury on it’s own.
