Gin and Tonic Flapjacks

Gin has become the in thing to drink recently hasn’t it, with all kinds of different flavours cropping up and various new tonic waters also emerging as the perfect accompaniment to this light, refreshing tipple. So really, it was only a matter of time before I made Gin and Tonic Flapjacks, ‘cos well it would be downright rude not to!

Taking the idea of using a drizzle (I can thank my Vegan Lemon Drizzle Flapjacks for that inspiring nugget) the flapjack base is infused with a teeny tiny bit of gin and heaps of zesty citrus flavours and then seductively drizzled with the good stuff.

It takes ice and a slice to a whole other level!

What’s In My Gin and Tonic Flapjacks?


  • 250g Oats
  • 100g Unsalted Butter
  • 100ml Honey
  • Zest of 1 Lime
  • Zest of 1 Lemon
  • 1 tbsp Gin

G&T drizzle

  • 100ml Tonic Water
  • 7ml Gin
  • 2tbsp Caster Sugar
  • Zest of 1 Lime
  • Zest of 1 Lemon

How Do I Make Gin and Tonic Flapjacks?

Melt the butter in a saucepan and stir in the honey, gin and lemon and lime zest.

Gently heat for 2 minutes, then take the saucepan off of the hob and stir in the oats.

Spoon the oat mixture into the holes of an individual flapjack tin and cook on a moderate heat for 15 minutes, or until the top has gone golden.

Whist the flapjacks are baking, put all of the G&T drizzle ingredients in a saucepan, bring up to the boil and then turn down the heat and allow to simmer for the 15 minutes.

When the flapjacks are ready, leave to cool in the tin for 10 minutes before carefully removing with a palette knife and allowing to cool completely on a rack.

Once cool, decorate the top of the flapjacks with a quarter slice of lemon and lime and then generously drizzle with the gin and tonic syrup.
