Ingredients You’ll Need

This recipe uses a special combo of gluten-free flours and real, quality ingredients that come together for soft, flavorful cookies. Keep an eye out for Dutch-process cocoa powder—it gives a deeper chocolate flavor without the acidity that can affect the texture.

• Blanched Almond Flour: This gives the cookies a tender crumb and subtle nutty flavor without overpowering the chocolate.
• Tapioca Flour: Adds chewiness and helps bind everything together naturally.
• Unsweetened Dutch Process Cocoa Powder: For that rich color and intense chocolate taste without bitterness.
• Baking Powder: A touch of lift to keep the cookies light.
• Salt: Enhances the chocolate flavor and balances the sweetness.
• Unsalted Butter: Use room temperature so it creams perfectly with the sugar.
• Organic Cane Sugar or Granulated Sugar: Sweetens up the dough with a clean flavor.
• Egg Yolk: Adds richness and tenderness.
• Vanilla Extract: Always a must to deepen cookie flavor.
• Marshmallow Cream: The base for that airy peanut butter fluff filling.
• Creamy Peanut Butter: Smooth style works best to avoid oil separation in the filling.
• Pure Maple Syrup: Adds subtle sweetness and a touch of complexity.
• Salt (for filling): Balances the filling’s flavors perfectly.

Variations

One of the best parts about this Halloween Gluten-Free Chocolate Sugar Cookies with Peanut Butter Fluff Filling Recipe is how fun it is to customize. I often switch up the fillings or play with the cookie shapes to suit the occasion or my mood.

• Swap the Fluff Filling: Sometimes, I substitute the peanut butter fluff with chocolate ganache or a cream cheese frosting for a different, indulgent vibe.
• Add Spices: For a cozy fall twist, add a pinch of cinnamon or pumpkin spice to the dough – I love how subtle warmth blends with chocolate.
• Use Different Nut Butters: If peanut allergies are a concern, almond or cashew butter work beautifully in the fluff filling.
• Decorate with Icing: Once cooled, you can decorate your cookie sandwiches with gluten-free royal icing or colorful sprinkles to amp up the festive look.

How to Make Halloween Gluten-Free Chocolate Sugar Cookies with Peanut Butter Fluff Filling Recipe

Step 1: Mix the Dry Ingredients Carefully

Start by whisking together the almond flour, tapioca flour, Dutch-process cocoa powder, baking powder, and salt in a small bowl. I love this part because the cocoa powder makes the dough look spooky and rich—perfect for Halloween! Make sure your powders are well combined so the flavor and rise are even in every bite.

Step 2: Cream Butter and Sugar

Using a stand mixer with the smaller 3-quart bowl is key here—you want the butter and sugar to cream fully into a light, fluffy texture. I learned the hard way that a bigger bowl just leaves the mixture stuck on the edges! Cream the unsalted butter with sugar on medium-high speed, scraping down the sides as needed, until you get a soft and airy base.

Step 3: Add Egg Yolk and Vanilla

Next, beat in the room-temperature egg yolk and vanilla extract until the mixture looks smooth and creamy. This step adds moisture and richness, making the cookies tender but firm enough to hold their shape when baked.

Step 4: Incorporate Dry Ingredients

Sprinkle the dry ingredients over the wet mixture gradually. Start mixing on low speed to avoid a flour cloud, then bump up to medium speed until the dough comes together, starts pulling away from the bowl’s edges, and no dry streaks remain. This is a moment where patience pays off—you’ll get a dough that’s pliable but not sticky.

Step 5: Chill the Dough

Shape the dough into a disc, wrap it tightly in plastic wrap, and refrigerate for at least one hour. Chilling is my favorite secret because it firms up the dough so it’s easier to roll and helps the cookies hold their shape during baking. Plus, it deepens the chocolate flavor.

Step 6: Roll and Cut Out Your Cookies

Preheat your oven to 350°F and line baking sheets with parchment paper. I always dust my working surface with cocoa powder instead of flour to avoid weird white streaks on the cookies—that’s a simple trick I discovered early on. Roll out the chilled dough to 1/4-inch thickness (or thinner if you’re going for delicate cookie sandwiches). Use your favorite Halloween-themed cookie cutters to cut shapes, leaving room for spreading on the baking sheets.

Step 7: Bake and Cool

Bake cookies for about 8 to 9 minutes until the edges are set but the centers stay soft—not dry! This timing is perfect for soft, chewy cookies that aren’t tough. Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely, which prevents breakage when assembling.

Step 8: Whip Up the Peanut Butter Fluff Filling

While the cookies cool, combine marshmallow cream, creamy peanut butter, maple syrup, and a pinch of salt in a small bowl. Microwave just 15 seconds—this step helps loosen the peanut butter for easier mixing. Stir until smooth and creamy, but don’t overheat or it’ll become oily. This filling is light, fluffy, and perfectly balanced.

Step 9: Assemble Your Cookie Sandwiches

Spread about a tablespoon of the peanut butter fluff onto the bottom half of each cookie, then gently press the matching top cookie on. The filling will naturally spread to the edges and get that classic sandwich look. My family goes crazy for these—definitely double the batch if you’re feeding a crowd!

How to Serve Halloween Gluten-Free Chocolate Sugar Cookies with Peanut Butter Fluff Filling Recipe

Garnishes

I love topping these cookie sandwiches with a sprinkle of edible glitter or a few mini chocolate chips to up the festive vibe. Sometimes, I pipe a bit of royal icing along the edges for a colorful, whimsical touch that kids adore. Freshly crushed salted peanuts on the filling edges add texture and look fantastic too.

Side Dishes

For a full Halloween-themed spread, I like pairing these cookies with a warm cup of spiced pumpkin latte or hot chocolate topped with whipped cream. They also go great with simple fresh fruit like sliced apples or orange segments to balance the richness.

Creative Ways to Present

Present your cookies arranged on a spooky-themed platter with spider web doilies or orange and black parchment paper underneath. For parties, place each cookie sandwich in clear cellophane bags tied with orange ribbons or Halloween-themed stickers—your guests will love the festive packaging and the anticipation it builds!

Make Ahead and Storage

Storing Leftovers

I store leftover cookie sandwiches in an airtight container at room temperature for up to three days. The cookies stay soft and the filling remains smooth without drying out, which is a nice bonus. If your kitchen is warm, pop the container in the fridge—but let them come to room temp before eating for the best flavor.

Freezing

You can freeze these cookie sandwiches by placing them on a baking sheet in a single layer until solid, then transferring them to a freezer bag. I freeze them without the filling first, then assemble after thawing. But if you’re in a pinch, freezing the fully assembled cookies works too—just allow extra thawing time.

Reheating

To revive cookies that have been refrigerated or frozen, I let them come to room temperature naturally, or warm gently in a low oven (about 300°F for 5 minutes). This brings back that soft, fresh-baked texture while keeping the peanut butter fluff creamy and dreamy.
