Midnight-dark keto crinkle cookies for Halloween. Oreo-style taste, low carb, soft middle, crisp edge, bright white crackle top. Easy steps, simple tools.
1 ¾ cups (175 g) blanched almond flour, super fine
⅓ cup (35 g) black cocoa powder
2 tbsp (12 g) natural cocoa powder
1 tsp espresso powder (optional)
1 tsp baking powder
¼ tsp baking soda
½ tsp fine sea salt
½ tsp xanthan gum
6 tbsp (85 g) unsalted butter, melted and cooled
2 large eggs, room temp
1 egg yolk, room temp
1 ½ tsp vanilla extract
¼ tsp almond extract (optional)
¾ cup (135 g) granulated allulose or erythritol (for dough)
½ cup (80 g) powdered erythritol (for coating)
Whisk almond flour, black cocoa, natural cocoa, espresso powder, baking powder, baking soda, salt, and xanthan gum.
In another bowl, whisk eggs, yolk, vanilla, almond extract, and the granulated sweetener until a little lighter. Slowly whisk in melted butter.
Add dry mix to wet. Fold to a thick, smooth dough. Cover and chill 45–60 minutes.
Heat oven to 350°F (175°C). Line a baking sheet with parchment. Put powdered erythritol in a shallow bowl.
Scoop 1-tbsp portions. Roll into balls. Coat well in powdered erythritol, wait 30 seconds, coat again.
Place 2 inches apart. Bake 10–12 minutes, until edges look set and tops crack. Centers should still be soft.
Cool on the tray 10 minutes. Move to a rack to cool fully.
Double coat in powdered erythritol for strong white crackles.
Allulose in the dough = softer, chewier cookies. Erythritol = crisper edge. Use powdered erythritol for the outer coat so it stays white.
If dough is sticky, chill longer or dampen hands.
Do not overbake; they firm up as they cool.
Storage: airtight at room temp 4 days; fridge 1 week; freeze up to 2 months.
Optional color pop: tap tops in orange-tinted powdered erythritol after the white coat.
