Keto Lemon Almond Cake Recipe

Soft and full of lemon flavor, this keto almond cake is based on a classic Spanish recipe. Made with almond flour, fresh lemon, and no sugar, it’s an easy low-carb dessert that fits into the keto diet without feeling like you’re missing out.

Ingredients

Scale
  • 2 cups almond flour

  • 1 tsp baking powder

  • Pinch of salt

  • 4 large eggs (room temperature)

  • 2/3 cup erythritol (or keto sweetener of choice)

  • Zest of 2 lemons

  • Juice of 1 lemon

  • 1/2 tsp almond extract

  • 1/4 cup olive oil

Optional Topping:

  • Extra lemon zest

  • Powdered erythritol for dusting

Instructions

  • Preheat oven to 350°F (175°C) and line an 8-inch round cake pan with parchment.

  • In a bowl, mix almond flour, baking powder, and salt.

  • In a large bowl, whisk eggs and sweetener until thick and pale.

  • Add lemon zest, juice, almond extract, and olive oil. Mix until smooth.

  • Fold in dry ingredients until combined. Batter will be thick.

  • Pour into the cake pan and smooth the top.

  • Bake 25–30 minutes until golden and set in the center.

  • Cool in pan 10 minutes, then on rack until fully cooled.

  • Optional: Top with powdered erythritol and more lemon zest.

Notes

Letting the cake cool fully helps it firm up and slice clean. Store in an airtight container for up to 4 days or freeze for up to 1 month. Great served with unsweetened whipped cream or a few berries.
