Coffee Oreo Whoopie Pies
These soft and cakey homemade oreo whoopie pies are filled with espresso Oreo buttercream. This twist on a classic cookie resembles a big soft Oreo!
Equipment
Ingredients
- ¾ cup dark brown sugar packed
- 1 large egg room temperature
- 1 large egg yolk room temperature
- ½ cup canola oil
- ½ cup full-fat sour cream room temperature (can also sub full-fat greek yogurt)
- ¼ cup brewed espresso or coffee
- 1 teaspoon vanilla extract
- 1 ⅔ cup all-purpose flour
- ⅓ cup dark cocoa powder
- ¼ teaspoon fine sea salt
- ½ tsp baking soda
- ½ teaspoon baking powder
- 10 tablespoon unsalted butter room temperature
- 1 cup powdered sugar
- ⅔ cup finely crushed oreo cookie crumbs
- 2 tbsp brewed coffee or espresso
Instructions
- Preheat the oven to 375 F/190 C and line two baking sheets with parchment paper.
- In a large bowl, whisk together the brown sugar, egg, egg yolk, oil, sour cream, espresso, and vanilla until well combined.
- Fold in the flour, cocoa powder, salt, baking soda, and baking powder until just combined.
- Scoop the dough with a standard (two tablespoon) cookie scoop onto the prepared baking sheets spaced at least two inches apart. Sprinkle with some of the oreo crumbs.
- Bake for 7-8 minutes. (for my oven, 7 minutes is perfect!)
- Allow them to cool completely on the tray while you make the filling.
- To make the buttercream, mix the butter in a mixing bowl until smooth and lump-free.
- Add in the powdered sugar and mix on low until combined, then mix on medium-high speed until it looks white and fluffy.
- Mix in the espresso on low until combined, then mix in the Oreo crumbs.
- To assemble, pipe a dollop of the buttercream onto the bottom of one cookie and sandwich it with the other. Enjoy!
Notes
Step-by-step process photos are provided above, in the body of this post.
- Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card.
- Use room temperature ingredients. Using room temperature ingredients creates a smooth, fully blended batter that will result in a uniform texture and even baking.
- Don't overbake them! These whoopie pies can easily overbake. I recommend baking one cookie first to get an idea of the baking time. For my oven, 7 minutes is perfect!
