Ingredients You’ll Need

Here’s a quick breakdown of what you’ll need to make these luscious whoopie pies.

For the whoopie pie cakes:

• 3/4 cup dark brown sugar, packed

• 1 large egg, room temperature

• 1 large egg yolk, room temperature

• 1/2 cup canola oil

• 1/2 cup full-fat sour cream (or full-fat Greek yogurt), room temperature

• 1/4 cup brewed espresso or coffee

• 1 tsp vanilla extract

• 1 2/3 cup all-purpose flour

• 1/3 cup dark cocoa powder

• 1/4 tsp fine sea salt

• 1/2 tsp baking soda

• 1/2 tsp baking powder

• Oreo crumbs for sprinkling

For the Oreo espresso buttercream filling:

• 10 tbsp unsalted butter, room temperature

• 1 cup powdered sugar

• 2 tbsp brewed espresso or coffee

• 2/3 cup finely crushed Oreo cookie crumbs

Kitchen Equipment Needed

• 2 Baking sheets

• Parchment paper

• Large mixing bowl

• Whisk

• Rubber spatula or wooden spoon

• Cookie scoop (2 tablespoon size)

• Electric hand mixer or stand mixer

• Piping bag or zip-top bag for filling

• Cooling rack (optional)

Step-by-Step Instructions

Step 1: Prepare the Oven and Pans

Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper. This prevents sticking and helps the pies bake evenly.

Step 2: Make the Whoopie Pie Batter

In a large bowl, whisk together the brown sugar, egg, egg yolk, oil, sour cream, brewed coffee, and vanilla until the mixture is smooth and cohesive.

Then, gently fold in the flour, cocoa powder, sea salt, baking soda, and baking powder until just combined. Don’t overmix — you want the batter to stay light and airy.

Step 3: Scoop and Bake

Using a standard 2-tablespoon cookie scoop, portion the batter onto the prepared baking sheets, spacing each scoop about 2 inches apart. Sprinkle a bit of crushed Oreo crumbs over the tops before baking.

Bake for 7-8 minutes. In most ovens, 7 minutes will yield the perfect soft, cakey texture. Let the cookies cool completely on the baking trays before assembling.

Step 4: Make the Oreo Espresso Buttercream

Using a mixer, beat the butter until smooth and creamy. Add powdered sugar gradually and mix on low until incorporated. Then increase the speed to medium-high and whip until fluffy and white.

Next, add the brewed espresso or coffee and beat on low until combined. Finally, fold in the finely crushed Oreo cookie crumbs. The result should be a soft, flavorful buttercream with texture from the cookie pieces.

Step 5: Assemble the Whoopie Pies

Pipe or spoon a generous dollop of the buttercream onto the flat side of one cookie and sandwich it with another. Gently press them together until the filling reaches the edges.

Repeat until all cookies are paired.

Storage Tips

• Room Temperature: Store assembled whoopie pies in an airtight container at room temperature for up to 2 days.

• Refrigerator: For longer freshness (especially in warmer climates), store in the fridge for up to 5 days. Let them come to room temperature before serving.

• Freezer: You can freeze the unfilled cakes for up to 2 months. Wrap them tightly in plastic wrap and store in a freezer-safe container. Defrost, then fill and assemble when ready.

Variations and Swaps

These whoopie pies are super versatile. Here are a few ways you can make them your own:

• Chocolate Chip Filling: Mix mini chocolate chips into the buttercream instead of Oreo crumbs.

• Mocha Kick: Add 1/2 tsp espresso powder to the dry ingredients for a deeper coffee flavor.

• Vanilla Cream Center: Skip the coffee in the buttercream and use 1 tsp vanilla extract for a classic twist.

• Mint Chocolate Oreo Filling: Use mint-flavored Oreos and add a drop of peppermint extract to the buttercream.

Perfect Pairings

Pair your Coffee Oreo Whoopie Pies with:

• Coffee or espresso for a flavor match made in heaven.

• A tall glass of milk for kids or the young at heart.

• Vanilla bean ice cream — try serving one whoopie pie warm with a scoop on top.

• Baileys or Kahlúa liqueur for an adult-friendly dessert experience.

Frequently Asked Questions (FAQ)

Can I make these whoopie pies ahead of time?

Yes! The cookie portions can be made a day in advance and stored at room temperature or frozen. Assemble just before serving for best texture.

I don’t have sour cream. What can I use instead?

You can substitute full-fat Greek yogurt in equal amounts. It will give a similar tang and moisture.

Can I reduce the sugar in this recipe?

While it’s possible to slightly reduce the sugar, doing so may alter the texture and structure of the whoopie pies. Try removing only 2-3 tablespoons at most.

Are these safe for kids to eat?

Yes — the espresso is mild and mostly for flavor. However, you can substitute with decaf coffee if you prefer a caffeine-free version.

Can I make these gluten-free?

Yes, simply use a cup-for-cup gluten-free all-purpose flour blend. Results may vary slightly but should still be delicious.
