🥥 Ingredients
- 🥜 1½ cups almond flour
- 🥥 ¼ cup coconut flour
- 🧂 ¼ teaspoon salt
- 🧈 ¾ cup unsalted butter, softened
- 🍬 ½ cup sugar-free sweetener (erythritol / monk fruit blend)
- 🌿 1 teaspoon vanilla extract
- 🍫 ¼ cup sugar-free chocolate chips
- 🥥 1 teaspoon coconut oil
- 🎃 Pumpkin cookie cutter + small knife for faces
👩🍳 Step-by-Step Directions
🔸 Step 1: Mix the Dry Ingredients
In a medium bowl, whisk together almond flour, coconut flour, and salt. Make sure there are no lumps — coconut flour can be clumpy. Set aside.
🔸 Step 2: Cream Butter & Sweetener
In a large bowl, beat softened butter, sugar-free sweetener, and vanilla extract with an electric mixer until light and fluffy (about 2 minutes). The mixture should look pale and airy.
🔸 Step 3: Make the Dough
Gradually add the dry ingredients into the butter mixture, mixing on low speed. Once combined, use your hands to bring it together into a smooth, non-sticky dough. If it feels too soft, chill 10 minutes.
🔸 Step 4: Roll & Chill
Place the dough between two sheets of parchment paper. Roll to ¼-inch thickness. Slide onto a baking sheet and refrigerate for 20–30 minutes — this is crucial for clean cuts.
🔸 Step 5: Cut & Bake
Use a pumpkin cookie cutter to cut shapes. For half of the pumpkins, cut out Jack-O’-Lantern faces (eyes, nose, mouth) using a small knife or mini cutters. Place all shapes on a parchment-lined tray. Chill again for 15–20 minutes. Bake at 350°F (175°C) for 6–7 minutes, until edges are just golden. Cool completely on the tray.
🔸 Step 6: Assemble the Sandwiches
Melt sugar-free chocolate chips + coconut oil in a microwave-safe bowl in 30-second bursts, stirring each time. Spread a thin layer of melted chocolate onto the solid pumpkin cookies (the ones without faces). Gently press a face cookie on top. Let set at room temp or refrigerate 10 minutes. BOO-tiful!
🎉 Ways to Present & Serve
🎃 Classic Stack: Serve the sandwich cookies on a wooden board with mini pumpkins and cinnamon sticks. Perfect for Halloween parties.
🍫 Drizzle Magic: After assembling, drizzle extra melted white (sugar-free) chocolate over the top for a ghostly web effect.
🧁 Keto Ice Cream Sandwiches: Use these as buns for a scoop of keto vanilla ice cream — press gently and freeze 20 minutes.
🎁 Giftable Treats: Stack 3–4 cookies in a clear cellophane bag, tie with orange ribbon, and attach a tag: “BOO — keto style!”
👻 Snack Board: Arrange alongside keto caramel dip, nuts, and dark chocolate shards. A low-carb Halloween grazing table!
📦 How to Store & How Long It Lasts
Countertop: Store in an airtight container at cool room temperature for up to 4 days. The cookies stay tender.
Refrigerator: Keeps well for up to 10 days. Let them sit 5 minutes at room temp before eating for best texture.
Freezer: Freeze unassembled cookies (with or without faces) for up to 3 months. Thaw in the fridge, then assemble fresh. Or freeze finished sandwiches in a single layer — thaw 15 minutes.
💡 Pro tip: Place parchment between layers to prevent sticking.
❓ FAQ — Your Keto Cookie Questions, Answered
Not recommended. Coconut flour absorbs moisture and gives structure. If you must, use 1¾ cups almond flour + 1 tbsp coconut flour, but texture will be more delicate.
Erythritol-based granular sweetener (like Swerve) or allulose. Avoid liquid sweeteners — they add too much moisture.
Your butter may have been too cold, or the flours weren’t measured correctly. Add 1–2 teaspoons of cold water or melted butter and mix again.
Yes! Swap butter for refined coconut oil or vegan butter (room temp). Use dairy-free chocolate chips.
First chill = easier rolling and cutting. Second chill = prevents spreading in the oven and keeps the faces sharp.
Absolutely! Ghosts, bats, or skulls work too. Just adjust baking time if shapes are much smaller or larger.
Use a sharp paring knife or small aspic cutters. Chill the cut-out cookies for 5 minutes in the freezer before carving — much cleaner lines.
Sure! Bake all cookies as single pumpkins with faces. They’re delicious plain — still only ~2g net carbs each.
Dough was too warm. Make sure your butter is softened, not melted. Chill the rolled dough the full 30 minutes, and don’t skip the second chill.
Yes! Doubles perfectly. Bake in batches, keeping unused dough in the fridge. These vanish fast at parties — you’ll want extra.
