How to Make Diabetic High-Protein Turtle Thumbprint Cookies

Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
Toast the chopped pecans in a dry skillet over medium heat for 4 to 5 minutes until fragrant. Allow them to cool completely.
In a medium bowl whisk together almond flour, oat flour, chocolate protein powder, cocoa powder, baking powder, and salt.
In a separate large bowl beat the softened butter with the monk fruit sweetener for about 2 minutes until light and fluffy.
Add the egg and vanilla extract and continue mixing until smooth.
Gradually add the dry ingredients into the wet ingredients, mixing on low speed until a soft chocolate dough forms.
Scoop approximately 2 tablespoons of dough for each cookie and roll into smooth balls.

Roll every dough ball generously in the chopped toasted pecans until fully coated.
Arrange the cookies on the prepared baking sheets about 2 inches apart.
Using your thumb or the back of a teaspoon, gently press an indentation into the center of each cookie.
Bake for 10 to 12 minutes until the cookies are just set around the edges.
If the indentations puff during baking, gently press them again while the cookies are still warm.
Meanwhile, prepare the sugar-free caramel by heating the butter and heavy cream over low heat. Stir in the monk fruit sweetener, vanilla, sea salt, and xanthan gum until smooth and thickened.
Fill each cooled cookie center generously with the warm caramel.
Melt the sugar-free chocolate chips with coconut oil until smooth and drizzle lightly over the caramel.
Sprinkle a few extra chopped toasted pecans over each cookie for the perfect bakery finish.
Allow the cookies to cool completely before serving so the caramel can set into a rich, gooey center.
Bake the cookies for another 1 to 2 minutes if needed, just until the edges are set while the centers remain soft. Avoid overbaking, as the cookies will continue to firm up as they cool.

Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. This helps prevent them from breaking while still warm.
Once the cookies are completely cool, spoon or pipe the sugar-free caramel into each thumbprint cavity until slightly mounded.
Drizzle the melted sugar-free dark chocolate over the caramel using a spoon or piping bag for a professional bakery appearance.
Sprinkle additional finely chopped toasted pecans over the caramel while it’s still soft so they adhere well.
Allow the cookies to rest for 20 to 30 minutes until the caramel and chocolate have slightly set.
Serve at room temperature for the perfect combination of chewy chocolate cookie, creamy caramel, and crunchy pecans.
Pair the cookies with unsweetened coffee, espresso, black tea, or a glass of unsweetened almond milk.
Store leftovers in an airtight container to maintain freshness.
Enjoy as a healthier dessert, holiday cookie, or special treat any time of the year.
