Keto Peanut Butter Thumbprint Cookies

I am not a professional baker, but I do like to create delicious and beautiful desserts. For typical Thumbprint Cookies, you simply roll the dough into balls and press your thumb to make an indentation for the filling. I could have done that with this recipe but, recently on vacation, I visited my favorite cooking/kitchen store and found a set of thumbprint cookie presses that take these simple cookies to a new level of elegance. (I found these cookie presses at Williams Sonoma, but you can find similar presses online, in other stores or on Amazon.) Fill them with either sugar free jam or chocolate ganache. Both pair exceptionally well with the peanut butter cookie base. Peanut butter & jelly? Peanut butter & chocolate? Which will be your favorite?

Keto Peanut Butter Thumbprint Cookies

Makes 20 cookies

Cookies:

1 cup almond flour

1/4 cup peanut butter powder (no sugar added)

1 tablespoon unflavored whey protein powder

2 tablespoons oat fiber powder (not oat flour!)

2 tablespoons coconut flour

1/4 teaspoon salt

8 tablespoons unsalted butter, softened (1 stick)

½ cup erythritol-based granulated sweetener (I used LaKanto Monkfruit Classic)

1 large egg

1 tablespoon low carb milk of choice

½ teaspoon vanilla extract

Jam Filling:

Sugar free jam (any flavor)

Chocolate Ganache Filling:

1 ounce heavy cream

1 ounce sugar free chocolate chips (such as Lily’s brand or Guittard Keto Chips)

1. In a medium bowl, whisk together the almond flour, peanut butter powder, whey protein powder, oat fiber, coconut flour and salt until no lumps remain; set aside. In a large bowl, beat the softened butter and 1/2 cup of erythritol sweetener together until creamy, using an electric mixer with a paddle attachment, if you have one. Beat in the egg, milk, and vanilla extract, and then beat in the dry ingredients until the dough comes together. 

2. Turn dough out onto a silicone mat or parchment paper that has been dusted with coconut flour. Pat dough into a rough circle and then top with a large piece of parchment paper or plastic wrap. Roll out the dough to about 5/8 inch thickness. Place the rolled out dough on a cookie sheet and chill in the refrigerator for about 30 minutes or in the freezer for 10 to 15 minutes. The dough is much easier to handle and will not stick to the cookie presses when cold. 

3. Preheat the oven to 325°F and line one large baking sheet with a silicone baking mat or parchment paper.

4. Using cookie presses with indentations in the center, cut out cookies and lift carefully with a spatula or knife and place on the lined cookie sheet. (Or roll into balls and press into the center with your thumb to create a depression to be filled with jam or chocolate ganache.) These cookies do not spread or puff up during baking.

5. Re-roll your dough and cut out more cookies. If your dough gets too soft to work with or begins sticking to the cookie cutters, roll it out to the proper thickness and return it to the refrigerator or freezer for a bit to cool and firm up again.

6. If using jam, go ahead and fill the depression with sugar free jam before baking (see photo below). If using chocolate ganache, bake the cookies first and allow them to cool completely before filling the indentation with ganache.

7. Bake the cookies for 14 to 16 minutes, or until they are golden brown around the edges. Remove from the oven and let the cookies cool on the pan until firm. The cookies will be quite soft when warm from the oven, but they will firm up as they cool. Remove to a wire rack to cool completely.

8. To make the chocolate ganache filling: Heat up the heavy cream until bubbles appear at the edges and the cream is quite hot and steamy. Remove from heat and add the chocolate chips. Allow the mixture to sit for several minutes undisturbed and then whisk until the chocolate is completely melted and the ganache is thick and creamy. Use a small spoon to carefully fill the center of each cookie. Refrigerate the cookies for 15 minutes or allow them to sit at room temperature until the ganache has cooled completely and firmed up. 

Notes: How many cookies you get depends on the size of your cookie cutters. It is best to use an erythritol-based sweetener for this recipe. Allulose can be substituted, or a combination of erythritol and allulose, but the cookies will be softer and more delicate when cooled.
