While tender, chocolatey donuts are perfect on their own, this keto breakfast recipe amps them up with a rich and sweet glaze. Pair with coffee and tea, or enjoy as dessert (if you can wait that long). At just over 2 net carbs per donut, they’re basically guilt-free. For more Bulletproof donuts, use grass-fed butter and mold-free coffee, plus full-fat coconut milk instead of heavy cream in the glaze.
Before we begin, a disclaimer in order: If you want to actually understand this topic, you must invest the time and mental energy to do so.  You really have to get into the details.  Obviously, I love the details and probably read 5 or 6 scientific papers every week on this topic (and others).  I don’t expect the casual reader to want to do this, and I view it as my role to synthesize this information and present it to you. But this is not a bumper-sticker issue.  I know it’s trendy to make blanket statements – ketosis is “unnatural,” for example, or ketosis is “superior” – but such statements mean nothing if you don’t understand the biochemistry and evolution of our species.  So, let’s agree to let the unsubstantiated statements and bumper stickers reside in the world of political debates and opinion-based discussions.  For this reason, I’ve deliberately broken this post down and only included this content (i.e., background) for Part I.
The 2 major issues that will lead to a flat loaf is not whipping the egg whites and gently folding them in OR using almond meal instead of a finely ground almond flour. If you've tried everything and they don't seem to be working for you, the next best option will be to make a larger recipe. Try making 1.5x this recipe (it's easy to do using the servings slide bar) and you'll have a much larger loaf.
