Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the oaty base and topping
45 g runny tahini
3 tablespoons coconut oil, melted
3 tablespoons maple syrup
1 small pinch of salt
125 g rolled oats
25 g rolled oats (reserved for topping)
125 g oat flour
30 g dark chocolate, finely chopped

For the chocolate tahini fudge layer
120 g dark chocolate, chopped
120 g runny tahini
2 tablespoons maple syrup
1 small pinch of salt
Optional: flaky salt for topping

Directions

Line a 6-inch square tin with baking parchment and set aside.
In a mixing bowl, stir together the tahini, melted coconut oil, maple syrup, and salt until smooth and glossy.
Add in 125 g rolled oats, the oat flour, and chopped dark chocolate. Mix well until a sticky, evenly combined mixture forms.
Press about three quarters of this mixture firmly into the prepared tin to create an even, compact base. Place the tin in the refrigerator to chill.
Stir the remaining 25 g rolled oats into the leftover oat mixture to create a crumble topping. Set aside.
To make the fudge layer, gently melt the dark chocolate until smooth. Stir in the tahini, maple syrup, and salt until thick and glossy.
Remove the base from the fridge and pour the chocolate tahini fudge evenly over the chilled base. Smooth the top with a spatula.
Sprinkle the oat crumble mixture evenly over the fudge layer and gently press it down.
Return the tin to the fridge and chill for 1 hour, or until fully set.
Once set, allow the bars to sit at room temperature for about 20 minutes, then slice into squares using a sharp knife. Sprinkle with flaky salt if desired.

Are these bars gluten-free?

Do these bars taste strongly of tahini?

Why is my base crumbly?

Can I keep these at room temperature?
