Protein-packed Halloween Chocolate Skillet sweetened protein protein powder, and actually sugar-free! An indulgent chocolatey halloween cast iron skillet dessert for the next party!

Another recipe that came from how much I loved the Protein Skillet Cookie recipe I made a while ago. This chocolate version was just a must.

And perfect timing with Halloween on this one, since I had some pumpkin spice white chocolate chips and pistachio ice cream lying around that I could use for the aesthetic!

Ingredients for Healthy Halloween Chocolate Skillet

These high protein halloween chocolate skillet is made with a few healthy ingredients (no sugar or butter) and some fun mix-ins.

Chocolate Protein Powder for healthy, sugar free pumpkin cookie
I used Quest Nutrition Chocolate whey-casein since it works best for baking.
Cocoa Powder
Unsweetened Applesauce
Whole Wheat Pastry Flour
Zero Calorie Brown Sugar – This is the Brown Monkfruit 1:1 Sugar Substitute from Lakanto, and keeps this recipe sugar free; (code HAYLSKITCHEN for a discount here)
Coconut Flour
An Egg
An Egg White
Almond Butter; I’d recommend American Dream Nut Butter Cookie Batter Almond Butter; Code HAYLSKITCHEN gives you a discount.
Baking Soda

And for the mix-ins:

Pumpkin Spice White Chocolate Baking Chips from Lily’s! You can use peanut butter chips or butterscotch chips for the color contrast though.

Peanut Butter Cup Candy; I use high-protein, low carb one from Quest Nutrition, but Reese’s works out as well.
Pretzels

Tips for Halloween Cast Iron Skillet Dessert

This Halloween cast iron skillet dessert recipe is super easy, but heres’ some tips to get it perfect every time.

Use whey-casein protein powder since it works well with the ratio of ingredients here; Whey absorbs less moisture, so you would have to reduce the amount of applesauce in this case.

Use room temperature ingredients so they mix well.

Remove bars from oven when the top of the center is cooked, but still soft; Chocolate skillet will continue to cook when cooling.

Store Leftover Halloween Chocolate Deep Dish Dessert

These leftover halloween chocolate deep dish dessert can be stored on the countertop, in the fridge or even frozen.

Leftover halloween chocolate skillet on the countertop for 1-2 days, and in the fridge for 5 days (in an airtight container).

To freeze healthy protein powder halloween skillet recipe, slice into pieces, place in freezer-safe zipper bag with parchment paper between each once, and keep 1-2 months; Don’t forget to thaw before eating!
