Using a large mixing bowl, mix together the dry ingredients (except the brown erythritol). In another large bowl mix together the brown erythritol with the melted butter and then add the remaining ingredients and combine.
Mix together the wet and dry ingredients until well combined. Spread the batter evenly into a generously greased 8 x 8 inch baking pan.
Bake at 350°F for 20-22 minutes and then turn oven off and leave for another 5 minutes. A toothpick inserted in the centre should come out clean. Allow to cool completely in the pan and then loosen edges with a rubber spatula before removing. (Refer to the detailed video instructions below if further clarification is needed)

Notes
Top Tip: To avoid the blondies from sticking to the pan, generously grease the baking pan if you do not use parchment paper. You can grease it with butter or coconut oil.
