• 1 teaspoon baking soda — leavening for spread and lift (check freshness)
• 1/2 teaspoon baking powder — extra lift (aluminum-free preferred)
• 1/2 teaspoon fine sea salt — balances sweetness (don’t skip)
• 1 cup mini semisweet chocolate chips (optional) — extra chocolate pops (good-quality chips)
• 3/4 cup creamy peanut butter — smooth filling texture (natural-style for stronger peanut)
• 4 tablespoons unsalted butter, softened — for filling creaminess (room temp)
• 1 1/2 cups powdered sugar, sifted — silky filling (sift to avoid grit)
• 2 tablespoons heavy cream or milk — adjusts filling consistency (start with 1 Tbsp, add as needed)
• 1/2 teaspoon vanilla extract — rounds out filling flavor (pure extract)
• 1/8 teaspoon fine sea salt — sharpens peanut butter taste (a pinch more if using natural PB)

Step-by-Step Method

Cream the Butter and Sugars

Preheat the oven to 350°F (175°C). Line two baking sheets with silicone mats or parchment. Cream 1 cup softened butter with granulated and brown sugars on medium speed until light and fluffy, 2 to 3 minutes. Scrape the bowl. Beat in the eggs one at a time. Mix in vanilla until fully combined and smooth.

Whisk the Dry Ingredients

In a separate bowl, whisk flour, sifted cocoa powder, baking soda, baking powder, and fine sea salt. Break up any cocoa lumps. Make sure the leaveners are evenly dispersed.

Keep the mixture light and airy. This promotes even mixing later. Set aside near the mixer so you can add it gradually.

Combine Wet and Dry

Add the dry ingredients to the creamed mixture on low speed. Mix just until a soft dough forms with no visible streaks of flour. Avoid overmixing to keep cookies tender.

Fold in mini chocolate chips if using. If the dough feels sticky, chill for 20 minutes for easier scooping.

Portion and Flatten

Scoop level 1-tablespoon portions of dough using a cookie scoop. Roll each portion into a smooth ball. Arrange on prepared sheets, spacing about 2 inches apart.

Slightly flatten each ball with your fingers or the bottom of a glass. Aim for uniform thickness to ensure even baking.

Bake and Cool

Bake for 8 to 10 minutes until tops are set and edges are just firm. Slightly underbake for soft, chewy cookies. Remove from the oven and let cookies cool on the sheet for 5 minutes.

Transfer to a wire rack to cool completely before filling. Match similar-sized cookies for neat sandwiches.

Beat the Filling Base

Beat creamy peanut butter with 4 tablespoons softened butter until smooth and fluffy. Use medium speed for 1 to 2 minutes. Scrape down the bowl.

Aim for a light, spreadable texture. This base should be cohesive and glossy, ready to take on the sugar without becoming grainy.

Finish the Peanut Butter Filling

Gradually beat in sifted powdered sugar until combined. Add heavy cream or milk, vanilla, and a pinch of salt. Mix until creamy and spreadable.

Adjust as needed: add a teaspoon of milk to loosen or a tablespoon of powdered sugar to thicken. Beat briefly to smooth any lumps.

Fill and Sandwich

Pair cookies by size. Spread or pipe 1 to 1 1/2 tablespoons filling onto the bottom of one cookie. Use an offset spatula or piping bag for neat edges.

Top with the second cookie. Gently press until the filling reaches the edges. For flair, roll edges in mini chips, chopped peanuts, or sprinkles.

Set and Serve

Refrigerate assembled cookies for 20 to 30 minutes to set the filling. Serve once firm to the touch for clean bites. Store in an airtight container at room temperature for 3 days or refrigerate up to a week.

Freeze up to 2 months with parchment between layers to prevent sticking.

Ingredient Swaps

• Dairy-free: Use vegan butter in both dough and filling; swap milk/cream with oat or almond milk; confirm chocolate chips are dairy-free.
• Gluten-free: Replace all-purpose flour with a 1:1 gluten-free baking blend that includes xanthan gum; chill dough 30 minutes for easier handling.
• Nut-free: Substitute sunflower seed butter or tahini for peanut butter; add a pinch more salt and 1–2 teaspoons extra powdered sugar to balance flavor/texture.
• Egg-free: Use 2 flax eggs (2 tbsp ground flax + 6 tbsp water, rested 10 minutes) or commercial egg replacer; bake toward the longer end and cool fully.
• Lower sugar: Reduce granulated sugar by 1/4 cup and use 60–70% dark mini chips; sweeten filling with 1 cup powdered sugar, adjusting consistency with milk.
• Budget/regional: Swap mini chips for chopped bar chocolate or omit; use regular table salt; use cocoa drink powder only in a pinch and cut sugar slightly.
• Flavor twists: Almond or hazelnut butter for PB; add instant espresso (1–2 tsp) to dough to boost chocolate; orange zest in filling; sprinkle flaky salt on assembled cookies.

You Must Know

Doneness • If bottoms are turning too dark while tops look matte, pull the tray once cookie edges look set and centers still feel soft with a gentle tap; carryover heat finishes them in 3–4 minutes, keeping chew without bitterness.

Troubleshoot • When dough smears on the scoop or hands, chill the bowl until firm to the touch but still pliable, about 15–20 minutes; cooler fat reduces spread so rounds bake evenly to 2.25–2.5 inches.

Flavor Boost • For deeper chocolate without extra sweetness, add 1–2 teaspoons espresso powder to the dry mix; it amplifies cocoa aromatics and reads as richer chocolate post-bake.

Swap • For a stronger peanut note and less sweetness, use 3/4 cup natural creamy peanut butter and reduce powdered sugar in the filling to 1–1 1/4 cups; add a pinch more salt (1/8–1/4 tsp) to keep flavors bright.

Scale • To yield 12 sandwiches, halve all ingredients and keep portions at a level 1 tablespoon; bake time stays the same, but start checking at 7 minutes as smaller batches warm faster in the oven.

Serving Tips

• Serve slightly chilled; the set filling gives clean bites and sturdy sandwiches.
• Pair with cold milk, hot coffee, or a creamy mocha for contrast.
• Plate in a swirl with warm chocolate drizzle and chopped roasted peanuts.
• Roll edges in mini chips or sprinkles for color; stack on a tiered stand.
• Crumble over vanilla ice cream; add warm fudge for an easy sundae.

Storage & Make-Ahead

Refrigerate assembled sandwich cookies in an airtight container for up to 1 week.

The filling sets best after 20–30 minutes in the fridge.

For make-ahead, bake cookies and store at room temperature 3 days.

Then fill before serving.

Cookies freeze well up to 2 months.

Separate layers with parchment.

Reheating

Reheat gently.

Microwave 5–10 seconds per cookie.

Oven at 300°F for 3–5 minutes on a sheet.

Stovetop skillet on low 1–2 minutes each side.

Avoid melting filling.

Serve slightly warm.

Ohio State Tailgate Tradition

Warm from a gentle reheat and still soft at the center, these sandwich cookies feel right at home amid scarlet-and-gray tents and the drumline’s thrum outside Ohio Stadium.

I slide open the container and a chocolatey hush floats up, chased by salty-sweet peanut butter. You take one, I take one, and we trade nods like seasoned Buckeyes.

I bake the cookies the night before, then chill the sandwiched stacks so the filling sets. At the tailgate, a quick warm-up on the cooler lid near the grill brings back that tender crumb and melty edge.

We pass them with napkins tucked into jacket sleeves, steam curling from cups of cocoa. Pep band horns flare, laughter lifts, and the cookies vanish—clean, decisive, victorious.

Frequently Asked Questions

Can I Make Them Gluten-Free Without Gritty Texture?

Yes—you can. I swap in a high-quality 1:1 gluten-free flour with xanthan gum, sift well, and let the dough rest 20 minutes. The cookies bake tender, not sandy, with fudgy centers and creamy, cloud-light filling.

How Do I Scale the Recipe for a Crowd?

Double or triple everything by weight; keep oven at 350°F and bake in batches. I whisk dry separately, rotate sheets, and cool completely. I scale filling 1:1.5:0.5 (PB:sugar:butter), adding cream until luxuriously spreadable.

What Altitude Adjustments Should I Use for Baking?

Use +15–25°F oven, reduce sugar 1–2 tablespoons, add 1–2 tablespoons flour, increase liquid 1–2 teaspoons, and shorten bake slightly. I’ll watch edges set, inhale chocolaty aroma, then cool quickly to lock tender, fudgy texture.

Are There Kid-Friendly Tasks for Helpers?

I’ll let kids scoop dough like tiny ice-cream moons, flatten gently, match cookie pairs, whisk the filling, and sprinkle edges. I’ll cue smells—buttery cocoa, nutty sweetness—and coach safe oven distance and sticky-finger cleanup.
