Betty Crocker broke recipes by shrinking boxes
To add to the frustration, one Redditor pointed out that the brand may have “tinkered with the amount of leaveners in the mix itself. … When [the cake] first comes out of the oven, it looks like a more substantial amount of cake but then shrinks as it cools down.” (We reached out to Betty Crocker to verify any ingredient changes and have yet to receive a response.)
