- 1/4 cup (50g) granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 3/4 cup (75g) rolled oats
- 3/4 cup (95g) all-purpose flour
- 1/4 cup (25g) unsweetened cocoa powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 3 oz (85g) dark chocolate, chopped or chips
- 1/2 cup (115g) unsalted butter, softened (for filling)
- 1 1/2 cups (180g) powdered sugar (for filling)
- 1 tsp vanilla extract (for filling)
- 1–2 tbsp milk or cream (for filling)
- Food coloring (optional: pastel pink, blue, green, yellow, etc.)
Instructions
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
- In a bowl, cream together butter and sugars until light and fluffy. Beat in the egg and vanilla extract.
- In another bowl, mix rolled oats, flour, cocoa powder, baking soda, and salt.
- Gradually add dry ingredients to the wet mixture and mix until combined.
- Fold in chopped dark chocolate or chips.
- Scoop tablespoons of dough onto the baking sheet, spacing them evenly. Flatten slightly.
- Bake for 10–12 minutes until set but still soft. Cool completely on a wire rack.
- For the filling, beat butter until creamy. Gradually add powdered sugar, vanilla, and milk to reach a spreadable consistency.
- Divide frosting and tint with food coloring as desired.
- Spread or pipe frosting on the flat side of one cookie and sandwich with another. Repeat with remaining cookies.
Notes
- Ensure cookies are completely cool before filling to prevent frosting from melting.
- Use gel food coloring for vibrant pastel hues without thinning the frosting.
- Store cookies in an airtight container at room temperature for up to 3 days.
