Baked smores bars with an oat base - make these gooey dessert bars for a bonfire night treat

Are baked smores bars easy to make?

Yes smores bars are very easy to make. They need some simple prep for the base and chocolate ganache layers. Then they are topped with marshmallows and grilled in the oven.

You start by preparing the biscuity base layer. We’ve made our base a gluten free oat crumble which is delicious all on its own. However if you prefer a more classic base, we’ve also included one using Digestive biscuits, in the recipe notes.

After the base is cooked until golden it’s left to cool. You then melt your chocolate with your cream and sugar to make a chocolate ganache and pour it over the top. Finally top it all with marshmallows and toast it under the grill until they go gooey and golden. Cut into bars and you’re good to go!

Ingredients

Crumbly oat base

  • 1 cup sunflower seeds (120 grams)
  • 3 cups gluten-free rolled oats (270 grams)*
  • 3 tablespoons oat flour (or plain flour)
  • 100 grams coconut sugar
  • ¾ cup butter melted (160 grams)
  • ½ tsp cinnamon
  • ¼ tsp salt
  • Up to 3 tbsp water if needed.

Notes for crumble base:

We recommend using classic rolled oats over instant oats or jumbo oats which can make the base too crumbly.

If you prefer a classic biscuit base then substitute the first 3 ingredients –  sunflower seeds, rolled oats and oat flour – with 750 grams Digestive biscuits. Replace the coconut sugar with light brown sugar. All the other ingredients and method remain the same.

Chocolate ganache

  • 200 grams milk chocolate
  • ¾ cup double cream
  • 1 tablespoon caster sugar

Topping

  • 40 marshmallows

Instructions

  1. Line a shallow baking tin with parchment paper and preheat the oven to 170°C. We used a 24 x 24cm (about 10 inch) square oven dish.
  2. Place all the ingredients for the oat base in a mixer and blend well. These are the sunflower seeds, rolled oats, oat flour, melted butter, salt, coconut sugar and cinnamon. Every minute pause the blender to scoop the mixture off of the sides. That way the mixture is fully blended.
  3. You should have a clumpy mixture. If needed add up to 3 tablespoons of water gradually to make it stickier.
  4. Spoon your mixture into your oven dish and press down on it firmly to make a thick crust that is evenly distributed. It should be about 1 cm depth.
  5. Prick with a fork and bake on the middle shelf of the oven for 10-15 minutes, or until the edges are golden.
  6. Remove and let the base cool completely. This step is important to stop the base from being too crumbly.
  7. Prepare the chocolate ganache. In a heatproof bowl place the milk chocolate in pieces, the double cream and the sugar. Set the bowl over a saucepan of boiling water. Keep stirring until the milk chocolate is all melted.
  8. Pour the chocolate ganache over the crumble base and spread it out evenly.
  9. Add the marshmallows on top by standing them upright over the chocolate layer. (Kids love to help with this part!)
  10. Place the dish in the oven with a top heat (or grill) for a few minutes until the marshmallows are browned. Keep a close eye on it as it cooks as the marshmallows can burn quickly.
  11. Remove and cut into bars or squares ready to serve.

1

Blend your base ingredients

In a medium size mixer, blend the sunflower seeds, rolled oats, oat flour (or plain flour), melted butter, salt, coconut sugar and cinnamon.

Pause the mixer a few times to scoop down any mixture that gets stuck up the sides.

You should get a dry base which sticks together in clumps. If it’s too dry add water 1 tablespoon at a time until you get the right consistency.
