In a microwave safe bowl, melt butter and chocolate for about 1 minute. Remove and stir well. You really want to use the heat within the butter and chocolate to melt the rest of the clumps. If you microwave until it's all melted, you've overcooked the chocolate. So get a spoon and start stirring. Add 10 seconds if needed but stir well before you decide to do that.
In a bowl, add eggs, sweetener, and vanilla and blend until light and frothy.
Pour the melted butter and chocolate into the bowl in a slow stream and beat again until it is well-incorporated.
Pour about 1/4 of the mixture into a Dash Mini Waffle Maker, and cook for 7-8 minutes, or until crispy.
Should make 4 waffles, with a little batter left over.
Serve these with whipped cream or syrup when they're warm for best results.
Don't over-microwave the chocolate, or it will burn. Only cook and stir until it's just smooth and melted.
These freeze well! Make a big batch and save some in the freezer to heat up later.
