Easy Keto Lemon Pound Cake Bars

A classic keto cake made into easy bite-sized bars today. These Easy Keto Lemon Pound Cake Bars are perfect for Easter, breakfast or a healthy anytime keto treat.
 I used a little butter for that great tasting cake but having the addition of Greek yoghurt really helps with the light and fluffiness of these lemon pound cake bars. Having a combination of flours too, rather than just one, also makes these nice and moist and spongy.

  • 3.5 tablespoons butter melted (or 50g)
  • 3 tablespoons unsweetened almond milk
  • 4 large eggs divided
  • ¼ cup Plain Greek yogurt
  • 1 teaspoon vanilla extract
  • 4 tablespoons lemon juice (apx. juice from 1.5 lemons)
  • 1 tablespoon lemon zest (apx, zest from 1 lemon)
  • 1.5 cups almond flour (or 150g)
  • ¼ cup coconut flour (or 30g)
  • 120 grams Swerve confectioners (½ cup plus 2 tbsp) (or Better than Sugar confectioners or low-carb sweetener of choice)
  • 1.5 teaspoons baking powder aluminum-free
  • 1 teaspoon baking soda
  • 1 pinch salt


  • Preheat the oven to  355F / 180C / 160 fan.
  • Add the butter and almond milk to a pan and simmer until slightly warm (don’t allow it to boil). (Option to microwave if you prefer). Allow to cool for 1 minute and add the egg yolks, yogurt, vanilla and lemon juice. Whisk with a hand balloon whisk to combine.
  • Place all the dry ingredients in a clean mixing bowl and stir.
  • Add in the egg yolk mix and whisk with the electric whisk until combined.
  • Whisk the egg whites in a clean mixing bowl using an electric whisk until thick and stiff peaks form.
  • Gently fold the egg whites through the lemon pound cake batter, or lightly beat with an electric whisk until smooth. Try not to over whisk so that batter doesn’t deflate.
  • Spoon the mixture into a grease proof lined tray (4 by 8 in) and bake for about 40 minutes or until you can insert and remove a skewer without crumbs sticking. Note: After 30 minutes loosely cover with a sheet of tin foil (don’t seal around the tray) this will prevent the top over browning whilst the cake continues to cook and firm up.
  • Remove the tin foil and allow to cool for 10 minutes in the tray and then on a wire rack before slicing. Note: These easy Keto Lemon Pound Cake Bars will firm up when cooled so try not to over-bake.
  • Storage: Tupperware in the fridge for up to 5 days
