Who would have thought making a cold pie in a cast iron skillet would be a thing…but I’m here to tell y’all…It. Is. A. Thing! A big yummy Thang!!!

Southern Cast Iron Inspiration

I bought this magazine, Southern Cast Iron, about 2 months ago and haven’t put it down since. I just love it when I find a new source of inspiration especially one with southern roots because food from the south made by a true southern cook (east Texas Warners specifically) is by far the best food on the planet! 

Just like my aunts to my cousins, my east Texan mom passed down the southern skill set of cooking the “right” way. Unfortunately for the waist line that almost innate southern talent comes a highly refined sweet tooth; am I right Mary?

Easy Key Lime Cast Iron Pie Crust

My cooking technique, a little of this and a little more of that, does not lend itself to ever following a recipe exactly, so of course, I didn’t do it here.  A little more texture was added to the crust with the macadamia nuts. Using a zester, zest about a half a lime (regular lime not key lime) and instead of 1 cup of crushed pretzels I cut it back to 1/2.

I must say the crust is my favorite part of this pie and could be used for almost any citrus flavor not just key lime.Jump to Recipe!

It takes about 14 graham cracker rectangles to make 2 cups of crushed crackers.

How to Make Key Lime Graham Cracker Crust

  • Crush the graham crackers, macadamia nuts, and pretzels in the blender (all separate) and transfer to a medium mixing bowl.
  • Stir the sugar into the crumb mixture and then add the melted butter. Mix until all ingredients are wet and malleable.
  • Spray your cast iron skillet (a glass dish can be substituted) with oil and pour the crust ingredients into the middle of the pan…start pressing to form a uniform crust on the bottom and sides of the pan (bottom of a drinking glass works really well).
  • Place in the freezer for at least 30 mins. The cast iron makes the crust super cold and super crunchy!
Little Red Skillet

This little red skillet was the first cooking utensil my mom ever gave me more than 30 years ago:) Do you ever get over missing your mom? This cute little pan is really a 8.5″ pan not 10″ like the recipe calls for so my crust was a little thicker, but who cares, the more crust the better!

Easy and Delish Key Lime Pie Filling

Next, whip up the filling!

  • Take the cool whip out of the freezer to thaws lightly.
  • While it’s thawing beat the cheese for a minute then add the rest of the filling ingredients except the whip.
  • Mix it all up until combined then fold in the slightly thawed cool whip.
  • Then add chopped up white chocolate morsels…Ha, Ha not following directions…again.
  • Spread mixture on top of the crust, sprinkle lime zest over, cover loosely with plastic wrap, and freeze for at least 6 hours or until firm.
Mix it up!

Last step!

  • Blend a handful of pretzels and white chocolate chips in blender until crumbly.
  • Sprinkle on thawed pie and place lime slices in a decorative pattern…if you’re decorative…or just serve it without if you’re not feeling it:)

Wallah! You are done!

Now it’s time to sit back and soak in all the hmmms, yummmms, and awesomeness of the moment. Get ready to be showered with love and affection for the rest of the day.

I surely don’t take credit for thinking up this wonderful dish but will take full responsibility for raising your cooking awareness to the art of cast iron desserting.
