1. Combine the wet ingredients
Place the cashew butter, honey, melted butter and vanilla extract in a bowl. Mix until smooth.
If the oil has separated in your nut butter jar, stir it thoroughly before measuring.
2. Make the cookie dough
Add the almond flour, vanilla protein powder and a pinch of salt. Mix into a firm, slightly sticky dough.
For the version without protein powder, use the full 145 grams of almond flour.
Fold in the chocolate chips last. If the mixture is still warm from the melted butter, let it cool slightly first to help the chips keep their shape.
3. Press the base into the tin
Line the tin with baking paper. Leave some paper overhanging the sides so you can lift out the slab later.
Spread the dough across the base and press down firmly and evenly. Refrigerate while you prepare the date caramel.
4. Make the date caramel
Soak the pitted dates in hot water for 10 minutes, then drain thoroughly.
Check that all stones have been removed. Place the dates in a food processor and blend into a thick, sticky paste. Scrape down the sides and blend again as needed.
The soaking water is not part of the recipe.
5. Add the caramel layer
Spoon the date paste onto the chilled base and spread evenly.
Use the back of a lightly dampened spoon or a spatula to smooth the layer. Work gently to avoid pulling up the base.
6. Add the chocolate
Melt the 100 grams of chocolate using a double boiler or carefully in the microwave.
If using a microwave, heat in short intervals and stir between each one. When using a double boiler, prevent water from getting into the chocolate.
Spread the melted chocolate over the date caramel and smooth the surface. Add the optional small pinch of sea salt.
7. Chill and slice
Refrigerate until the base, date caramel and chocolate topping are sufficiently firm.
Lift the slab out of the tin and cut into 12 equal bars. For a smaller serving, cut each bar in half.
