Toast the pecans: Add chopped pecans to a dry skillet over medium heat.
Stir for 3–5 minutes until fragrant and lightly golden. Remove from heat and let them cool completely.
Cream the base: In a mixing bowl, beat the softened butter and cream cheese until smooth and fluffy, about 1–2 minutes. Scrape down the sides as needed.
Sweeten and flavor: Add the powdered sweetener, maple extract or keto maple syrup, vanilla, cinnamon, and a pinch of salt.
Beat again until fully combined. Taste and adjust sweetness and maple intensity.
Add pecans: Fold in most of the toasted pecans, reserving a tablespoon or two for topping if you like a crunch on the outside.
Chill the mixture: Place the bowl in the fridge for 15–20 minutes to firm up. This makes shaping easier and cleaner.
Shape the fat bombs: Use a small cookie scoop or tablespoon to portion the mixture into 14–18 balls.
Roll gently between your palms. Press the tops into the reserved pecans, if using.
Optional chocolate drizzle: Melt sugar-free chocolate chips and lightly drizzle over each fat bomb. Chill for 5–10 minutes to set.
Set and store: Place the fat bombs on a parchment-lined tray and refrigerate for at least 30 minutes before serving.
