Step 1

First, process the whole flax seeds into a floury consistency in an electric coffee/spice grinder or small blender jug.

Step 2

Then, mix all the dry ingredients in a food processor, before adding the dates and vanilla extract.

Step 3

Process again until it forms a dough that sticks together when pressed between your fingers. This can take a few minutes. If it's still too dry, add more dates or a small amount of maple syrup.

Step 4

Next, line a 6-inch square baking pan (double the recipe for an 8 or 9-inch pan) with lightly greased parchment paper, leaving a 2-inch overhang on both sides. Transfer the dough to the prepared baking dish, pressing it down into an even layer.

Step 5

Transfer the caramel ingredients to a saucepan and bring to a boil, then immediately reduce to a simmer and whisk often, for 10-15 minutes, until the mixture thickens.

Step 6

Pour the caramel layer over the brownie base and transfer it to the freezer for 30 minutes.Alternatively, make an even healthier date caramel sauce. The full ingredient amounts and instructions are in the recipe notes.

Step 7

Use a warm water bath or double boiler (a bowl set over a pan of simmering water) to melt the chocolate and coconut oil. Stir until smooth and melted.

Step 8

Pour that over the caramel layer and return to the freezer for 5 minutes.

Step 9

Finally, cut the vegan brownies into bars (using a hot knife is best), and enjoy!
