St. Patrick’s Day Whoopie Pies

St. Patrick’s Day Whoopie Pies

These delicious little cakes are a play on the traditional chocolate and vanilla whoopie pie but with the addition of a bright green buttercream to get you in the mood for St Patrick’s Day.



Whoopie Pies

150g chocolate (we recommend minimum 70% cocoa solids)

125g butter

3 large eggs

225g sugar

1 tsp vanilla extract

250g plain flour

30g cocoa powder

½ tsp baking power

Makes 12

Buttercream Filling

140g butter (room temperature)

280g icing sugar

Green food colouring (we recommend 100% natural food dye)


  • Preheat the oven to 180C/250F/Gas 4
  • Line two baking trays with greaseproof paper or a silicone sheet
  • Melt the chocolate and butter together in a heatproof bowl over a pan of simmering water, ensuring the bowl does not touch the water.
  • In another bowl, whisk together the eggs, sugar and vanilla, then fold in the melted chocolate mixture.
  • Sift the flour, cocoa and baking powder in to the bowl and fold in gently.
  • Drop a tablespoon of mixture on to the baking trays to create each whoopie pie half. Aim for 12 per sheet.
  • Bake for 6-8 minutes, or until they feel springy to the touch and a toothpick comes out clean when inserted in to the top.
  • Remove from the oven and cool on a wire rack.
  • To make the filling, cream together the soft butter and icing sugar until smooth.
  • Add food colouring (paste works best) until the desired shade of St Patrick’s Day green!
  • Spoon the filling on to one half of the whoopie pie, and sandwich with another.
