Keto Lemon Danish: Low-Carb Egg-Fast Filling Recipe

Many long-time low-carbers know the classic low-carb Mock Danish. This version is an Egg Fast–friendly twist with a bright lemon filling.

Keto Egg Fast Lemon-Filled Danish

Remember those store-bought danishes with a little lemony center? This recipe recreates that flavor in a simple, Egg Fast–approved form. It’s based on the familiar Mock Danish but adds a lemony filling to brighten things up.

If you’re tired of basic egg preparations—boiled, scrambled, poached or deviled—this recipe offers a tasty break and can make the Egg Fast feel more enjoyable.

I typically avoid sweeteners where possible, but for this lemon danish I recommend using a liquid stevia on the Egg Fast so you can easily adjust sweetness to taste.


Tools

  • Small microwavable bowl
  • Silicone baking cups or small ramekins
  • Rubber spatula or fork

Ingredients

Danish

  • 4 tbsp (about 2 oz) full-fat brick-style cream cheese
  • 2 eggs
  • Stevia to taste (equivalent to about 2 tsp sugar, or to preference)
  • Cinnamon for sprinkling

Filling

  • 1 tbsp coconut oil
  • 1 tbsp butter
  • 1 tsp lemon extract or lemon zest (or True Lemon packets if preferred)
  • Stevia or other zero-carb sweetener to taste

Instructions

Make the Danish

  1. Place cream cheese in a small microwavable bowl and soften for 30–60 seconds, depending on your microwave.
  2. Stir the cream cheese with a fork until smooth and creamy.
  3. Add the eggs and beat until fully combined. Sweeten with stevia to taste.
  4. Divide the mixture evenly between two large silicone baking cups or ramekins.
  5. Lightly sprinkle the tops with cinnamon.
  6. Place the cups on a microwave-safe plate and cook, checking every 20–30 seconds, until set. While still warm, press a small well into the center of each danish. Transfer to the refrigerator to cool.

Make the Lemon Filling

  1. Combine the coconut oil and butter in a small glass dish.
  2. Microwave briefly (about 30 seconds) until melted, then stir until smooth.
  3. Add lemon extract or zest and sweeten with stevia to taste.
  4. Chill in the refrigerator until the mixture begins to thicken and turn pale yellow.

Once chilled and slightly thickened, spoon the lemon filling into the wells of the two danishes. Return them to the fridge until fully cooled and the filling has set.

For Egg Fast tracking, each danish counts as 1 egg, 1 cheese, and 1 fat.
