COLLAGEN COOKIE SKILLET FOR TWO
This Collagen Cookie Skillet for Two is the ultimate healthy Valentine's dessert! It's got chewy cookie edges, a gooey cookie center, and melty chocolate chips throughout. But that's not all - this giant cookie is also lower in sugar with added collagen protein, and gluten free and dairy free. Try it with protein ice cream for an extra protein boost!
Did you know? Your bones are made mostly of collagen! Research suggests that taking daily collagen supplements may help inhibit the bone loss. (source)

Choosing the best collagen
I choose marine collagen because it's higher in Type I collagen (the most important kind) and typically lower in contaminants than bovine collagen. My favorite brand is LIV Body Marine Collagen (I used the Flavorless for this recipe). Feel free to use my code "SARAHWILKINS" for free shipping on all LIV Body products!
This cookie skillet can also be made without the collagen - however, I do NOT recommend substituting whey or vegan protein since they behave much differently than collagen protein.

Flour recommendations
For this recipe, I used gluten free baking flour and coconut flour to achieve a cookie-like texture. You can substitute all purpose flour, brown rice flour, cake flour, cassava flour, or oat flour for the gluten free baking flour. To swap out the coconut flour, I would suggest twice as much baking flour (two tablespoons).

Sweetener recommendations
To sweeten this cookie skillet, I used this brown sugar alternative. I just love the hint of brown sugar flavor! You can use any sugar-free brown sugar alternative, such as Lakanto Golden, Sukrin Gold, Swerve Brown, or Truvia Sweet Complete Brown. You can also use regular brown sugar or coconut sugar if you’re not worried about the added sugar! Baking stevia, granulated erythritol, granulated monk fruit, or a granulated white sugar will also work, but won’t taste quite as rich. If using stevia extract or drops, please check the brand-specific conversion chart :)

Wet ingredients
Besides baking soda and salt, the only other ingredients are egg whites, vegan butter, and peanut butter. You can also use cashew butter or tahini (sesame seed butter)! You can substitute the egg whites for one whole egg, and the vegan butter for regular unsalted butter or coconut butter.
Finally, I used dairy free chocolate chips and natural colored sprinkles, but both of these can be swapped for whatever add-ins you like.

Ingredients
- 1 1/2 tbsp. vegan butter* (or unsalted butter)
- 1/3 cup sugar free brown sugar alternative* (I used one that measures like sugar)
- 1 1/2 tbsp. peanut butter* (or tahini)
- 3/4 tsp. pure vanilla extract
- 1/4 cup (2 large) egg whites* (or 1 whole egg)
- 1/3 cup (40g) gluten-free baking flour
- 1 tbsp. coconut flour (or 2 tbsp. additional baking flour)

- Natural colored sprinkles (optional)
*See blog above for substitutions and notes.
Directions
- Preheat the oven to 350 degrees F.
- Using an oven-safe skillet, melt butter over medium-low heat and then add brown sugar alternative. Simmer until slightly richer in color and thickened, about 2 minutes.
- Remove from heat and stir in peanut butter and vanilla extract.
- Let cool a few minutes until just warm, not hot.
- Meanwhile, whisk together flours, collagen, baking soda, and salt in a small mixing bowl.
- Whisk egg whites into skillet mixture once cooled (you don't want the egg to cook).
- Add dry ingredients to skillet, stirring until no dry clumps remain.
- Sprinkle chocolate chips on top.
- Bake in preheated oven for 12-17 minutes until center is set but still gooey.
Let cool for slightly before serving. Top with dairy-free ice cream if desired!

VEGAN PROTEIN PEACH COBBLER
When peach season rolls around, I just can't resist the idea of making Peach Crisp or Peach Cobbler. Because as much as I love fresh, juicy peaches... there's just something about baked peaches with a hint of cinnamon and dairy free ice cream! This comforting Vegan Protein Peach Cobbler is just as satisfying as the classic, but with less sugar, more protein, and a bit less fat. Oh, and it's gluten-free and dairy-free!
CHOCOLATE PEANUT PROTEIN CANDY BARS (VEGAN)
PUMPKIN CHIP PROTEIN BREAD (GLUTEN FREE, DAIRY FREE)
This Pumpkin Chip Protein Bread has a rich, tender texture full of pumpkin spice and chocolate chips (no dry protein bread here). The kids and I can't get enough! Best of all, it's gluten-free, dairy-free, nut-free and easily made egg-free and vegan.
