Consistently good quality

Another order from Oat Haus, and it was just as expected. I got the Variety Pack this time, which included the Blueberry Pie and Brownie Batter Granola Butter. Delivery took about 4 days to get to my place in Ohio. Everything was well-packaged as usual. It's nice knowing what you're going to get, and they always deliver on quality. I'll definitely be back for more when these jars run out.

Great value, tasty product

This was my first time trying Granola Butter, and I picked up the Birthday Cake flavor. I was looking for a nut-free spread and this seemed like a good deal, especially with the first order discount. The texture was really smooth, and the flavor was surprisingly good without being too sweet. Shipping was free because my order was over 50 bucks, which is always a plus. It felt like a good purchase overall, definitely worth trying.

Does anyone know if they ever do more than one discount at a time? Got a first-time code but also saw some influencer codes floating around.

J Jacob Jones 2 weeks ago

Nah, pretty sure it's just one code per order. Tried to stack once and it didn't work.

R Ryan Roberts 1 week ago

Yeah, they're usually one and done with discounts. You can use an influencer code or the first-time one, but not both. Unless you're on a subscription, those discounts apply automatically but you still can't add another promo code on top, afaik.

How long does a jar last after you open it? Wondering if I should get a big one or start with minis.

M Megan Thomas 3 weeks ago

A few weeks at room temp. I usually put it in the fridge after that and it's good for a while.

I've kept an open jar in the pantry for like a month and it was fine. They say it lasts longer in the fridge though, so if you're worried just pop it in there.

Hey guys, thinking of trying this out for my kid's lunchbox. Is it actually safe for school or just saying that?

B Betty 1 month ago

Yeah it's actually school-safe, no nuts or anything. My son takes it daily.

A Ashley Gonzalez 1 month ago

Totally. It's like, specifically made to be allergen-friendly, so they advertise it as school-safe because it is. My daughter's school has super strict rules and this passes.

Is this stuff any good compared to like, SunButter? That's what we usually get but looking for something new.

B Brittany Roberts 3 weeks ago

It's totally different! SunButter is good but this is much creamier, more like a spreadable granola bar. Less 'nutty' taste.

O Olivia T. 2 weeks ago

Oh, it's way better than SunButter if you ask me. Different texture, much smoother, and the flavors are really unique. It's more oat-y, obviously, but in a good way. I prefer it now.
