Her tip of making bigger cakes from mixes I use ALL the time, I've even printed it out and keep it right in with my cake mix container.
But with this tip she has topped the cake (so to speak). She found the tip at Simply Recipes and I'm so happy she posted it.
Use the blender you already have and see if a mason jar fits... lucky me one of mine does! Oh the possibilities! Grind flax seeds right in it's own storage container, coffee beans, whipped cream, spices. I can then use my vacuum sealer and seal a canning lid on the jar, or use an old mayonnaise lid which fits perfectly on a mason jar and pop in the fridge. No scraping out the blender container, no washing, an unlimited supply of "containers." I'm giddy :) LOL
Here's my blender in action with a 1 1/2 quart jar but any size wide mouth mason jar would work :) My KitchenAid uses wide mouth but some people are saying standard mouth works with their blenders.
So if you haven't checked out Tipnut.com, it's time!
