Just took it out of the oven and it is delicious!!
Thank you for the recipe.


It looks pretty! I wish I could leave a picture of it!


This is SO pretty and such a lovely tasting cake! I used cream cheese rather than sour cream as that’s all I had on hand, but it still tasted great. For my sweetener I used 3/4 cup erythritol and 1/4 tsp monk fruit sweetener – perfect. Thanks so much for a wonderful recipe, we really enjoyed this :)


Hi sorry if I missed this in the above post. But the nutrition facts, is that per piece or for the whole loaf?

The whole loaf cannot possibly contain only 209 calories. Four eggs alone are 280 calories. So, it follows that it must be nutritional info per piece. =)


This marble loaf is wonderfully moist and just delicious. I used a 9×5 silicon loaf pan (sprayed with coconut oil) and it was ready at 40 minutes for me. Left it in the pan to cool and turned it out while still just warm. My husband is diabetic and he thought he’d died and gone to heaven! Unfortunately, we ate 2 thick slices each before I could get it into the freezer. So quick and easy too. Thank you so much. You are the best. Luv your other cooking blog too.


Hello, I just put the cake in the oven and realized the description of your cake is a loaf and the directions say bundt pan. I used a bundt pan and want to know if I should alter the cooking time? Thanks so much!


Hi! Do you mean BREAD pan? I have never seen a 9 X 5 Bundt pan. I thought I would try this in silicon. It sounds wonderful. thanks!


Great looking recipe and one l will try!
Just one thing: l think the instruction to use a 9×5 bundt pan should be loaf pan. I’m sure most can figure that out, but it might confuse a novice. :-)
You develop the most wonderful LC recipes. Thank you! You make a huge difference to the low carb world.
