Keto Lemon Poppy Cake

I’m not sure how lemon and poppy seeds ever became the perfect marriage, but they did. Poppy seeds are seeds of the opium plant, but are not considered a pharmaceutical. Does anyone remember, though, when Elaine on Seinfield flunked a drug test because she was eating poppy seeds muffins. I’m not too worried about this as breads, bagels and muffins are made with poppy seeds all day long.

You can make this recipe into 12 over-sized muffins, my famous Lala Cakes, or a bundt cake. This is best topped with a sugar free lemon glaze and not a frosting or buttercream.

Swerve is my go to keto sweetener. Read here why.

    1. Joann, it’s hard for me to know what you did wrong. The eggs are beaten until fluffy. Oil streamed in. Add lemon juice, swerve, rest of dry ingredients. It’s not really possible for the eggs to separate from all of those ingredients? I suggest you look at the directions again and get back to me on what you did. I have made the bundt cake many many times for my bakery and I’ve made this batter at least 1,000 times. The eggs aren’t able to separate from the ingredients, so I’m stumped.

      1. Okay, I will give it another try and let you know how it goes. This one still tastes great aside from the egg issue.

  1. I just want to thank you for what you do.
