If not making homemade hearts, skip to step 4. Otherwise, melt the dark chocolate and coconut oil together.
Pour about 1 tsp of melted chocolate into each heart cavity of the silicon mold. Ensure the chocolate coats all sides. Freeze for 30 minutes to harden.
Add peanut butter to each cavity and top with more melted chocolate. Freeze for 1 hour until firm.
In a bowl, whisk together maple syrup, vanilla extract, and peanut butter.
Mix in almond flour and baking soda until a dough forms.
Roll dough into balls, flatten slightly, and place on a baking sheet. Bake for 13 minutes.
After baking, let cookies cool for 5 minutes, then press a heart into the center of each cookie. Enjoy!
