Kodiak Cakes Flapjack & Waffle Mix Expired

I have eaten these nearly every day for the last 1-2 years. They are a healthier alternative to regular pancakes and taste good (optional: add a pinch of cinnamon if you want). Obviously dousing these with Syrup or using a lot of butter will not make these "healthy." So for those more health conscious, I would recommend eating these with a small amount of syrup, sugar free syrup, or PB fit peanut butter that is a bit runny.

Ideal cooking instructions for me is 1.7g water : 1g pancake mix. This comes out to about 3oz of water to 1/2 cup mix. The instructions on the box have it at 1 cup water to 1 cup mix which is 240g water to 106g mix which will make these WAY too thin.

1. Add water to dry mix. Limit mixing to preserve CO2/promote rising
2. Let sit for 5 minutes. Preheat pan on medium
3. Add tsp of butter to the pan.
4. Add batter to pan. Let it sit for ~5 minutes. You should see the batter bubble slowly as CO2 escapes. (It should barely sizzle. If it sizzles a lot or if you smell butter burning, turn down the heat).
5. Once the top no longer looks wet (it should look dry), flip it
6. Let sit for 5 more minutes. Rotating it in the pan every couple minutes.
7. Turn off heat and flip again to reheat the other side and let it sit for 1-2 minutes.

The result should be a fluffy-ish pancake that is crisp on the exterior but slightly cakey in the interior. It shouldn't be that dry unless that is your preference.

To clarify this is but one get one free - correct? At least this is what my coupon stated. So basically not free - more like half price.

EDIT: The printed coupon does say get one free. The electronic coupon sent to my phone says BOGO

I tried Walmart self checkout. The coupon scanned but the coupon amount was $0.00. So no discount with scanning by myself. The cashier would not override it. Hope others have better luck.
