Step 1

First, make the caramel. Melt the butter in a saucepan and let it brown. Stir continuously to ensure it does not burn. Now add the heavy cream and powdered sweetener. Stir. Bring to a boil and then let the mixture reduce over a low heat until it has thickened - about 5-7 minutes. Add salt to taste (I used about 1/2 tsp) and set aside to cool.

Step 2

Preheat the oven to 180C/350F and line a 7x8 inch baking tray or casserole dish with parchment paper.

Step 3

For the brownie batter, stir together the dry ingredients in a bowl - coconut flour, unsweetened cocoa powder, baking powder and powdered sweetener, breaking up all lumps.

Step 4

Now add the wet ingredients - beaten eggs, melted and cooled butter and almond milk. Blend using an electric mixer.

Step 5

Last, stir in the sugar free chocolate chips.

Step 6

Dollop 2/3 of the batter into the tray and spoon the caramel into the gaps. Add the remaining brownie batter on top of the caramel. Gently pound the tray onto the counter so the batter can self-level. (Cover stone surfaces with a dishcloth or towel first).

Step 7

Now, swirl a knife through the batter in a slalom motion - first across from side to side, then lengthways. Pound the baking pan on the counter to self-level again.

Step 8

Bake for about 25 minutes. You want the top to be set but the centre still jiggly.

Step 9

Let cool completely before slicing into 12 squares.
