Step‑by‑Step Instructions for Keto Peanut Butter Blossom Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring the perfect texture of your Keto Peanut Butter Blossom Cookies. While the oven is heating up, gather your ingredients and line a baking sheet with parchment paper to make clean-up a breeze.
Step 2: Melt Butter and Peanut Butter
In a microwavable bowl, combine the salted butter and unsweetened peanut butter. Microwave the mixture in short bursts, stirring after each interval until it becomes smooth and well-blended, about 30-60 seconds total. This velvety blend forms the base of your cookies, enhancing their rich flavor.
Step 3: Mix in the Sweeteners
Once your butter and peanut butter are melted, add the vanilla extract, liquid stevia, and monk fruit allulose confectioners sweetener to the bowl. Stir the mixture thoroughly until everything is evenly combined and smooth, about 1-2 minutes. This combination of sweeteners ensures that your cookies are delicious without the carbs.
Step 4: Incorporate the Egg
Next, beat the egg in a separate bowl and then add it to your mixture. Mix well until the dough is cohesive, which should take about 1 minute. The beaten egg acts as a binder, ensuring that your Keto Peanut Butter Blossom Cookies have the right texture when baked.
Step 5: Form the Cookie Dough
Using a cookie scoop or your hands, portion the dough into approximately 20 equal balls. Place them on the lined baking sheet, spacing them at least 2 inches apart. This spacing allows the cookies to spread as they bake, resulting in that perfect chewy texture.
Step 6: Create Wells for Chocolate
Take a teaspoon and gently press down in the center of each cookie ball to create a small well. Be careful not to press all the way through; you want enough space for the chocolate filling later. This well is essential for achieving the iconic look of Peanut Butter Blossom Cookies.
Step 7: Bake the Cookies
Place the baking sheet in your preheated oven and bake for about 10 minutes. The cookies should be lightly golden brown around the edges but still soft in the center. Keep an eye on them as they bake; you can reshape the wells if needed right after removing them from the oven.
Step 8: Cool and Prepare Chocolate
Allow the cookies to cool completely on the baking sheet. In the meantime, melt the sugar-free chocolate chips with the additional salted butter in a small bowl, using a microwave or double boiler. Stir until creamy and smooth, which will only take a couple of minutes.
Step 9: Fill with Chocolate
Once the cookies are fully cooled, carefully spoon the melted chocolate into the wells of each cookie. The warm chocolate center will add a delightful richness to your Keto Peanut Butter Blossom Cookies, making them irresistible.
Step 10: Let the Chocolate Set
Allow the filled cookies to sit at room temperature for about 10-15 minutes until the chocolate has firmed up slightly. This step is essential for that perfect bite where the soft, chewy cookie meets the delectable chocolate center, ready for serving!
