While a low carb lifestyle usually means a lot less sugar and sweetness in your life, there are some decent sugar replacement options out there. If you’re interested in enjoying something sugar-like, one of my favorites is Lakanto’s monkfruit powered golden sugar substitute.
I’ve been using it specifically to sweeten warm beverages (bullet coffee, yellow chai), so cannot currently report on how it behaves during baking. (some sugar alcohols don’t hold up well to the oven – there can be issues with things not browning and a cooling sensation in the mouth can also occur depending on what’s being used…)
