Ingredients
Dry Ingredients:
2 cups (200g) blanched almond flour (spooned & leveled)
¼ cup (30g) coconut flour
⅓ cup (65g) granulated keto-friendly sweetener (such as Lakanto, Swerve, or Allulose)*
2 tablespoons poppy seeds
2 teaspoons baking powder
¼ teaspoon salt
Wet Ingredients:
4 large eggs, at room temperature
½ cup (120ml) unsalted butter, melted and slightly cooled (or coconut oil for dairy-free)
⅓ cup (80ml) unsweetened almond milk (or any milk of your choice), at room temperature
¼ cup (60ml) fresh lemon juice (about 2 large lemons)
Zest of 2 large lemons (about 2 tablespoons)
1 teaspoon vanilla extract
For the Glaze (Optional but Recommended):
½ cup (60g) powdered keto-friendly sweetener (like Swerve Confectioners)
2-3 tablespoons fresh lemon juice
**Note on Sweeteners: Using Allulose or a blend that contains Allulose will result in a softer, more sugar-like muffin that doesn’t recrystallize upon cooling. If using erythritol-based sweeteners (like Swerve), the muffins will be delicious fresh but may become a bit more firm the next day.
Instructions
Preheat & Prepare: Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners or generously grease the cups with non-stick spray to prevent sticking.
Combine Dry Ingredients: In a large mixing bowl, whisk together the almond flour, coconut flour, granulated sweetener, poppy seeds, baking powder, and salt. Make sure to break up any clumps in the almond flour.
Combine Wet Ingredients: In a separate medium bowl or large measuring cup, whisk the eggs until they are frothy. Add the melted butter (or coconut oil), almond milk, fresh lemon juice, lemon zest, and vanilla extract. Whisk until everything is well combined.
Mix Wet into Dry: Pour the wet ingredients into the bowl with the dry ingredients. Using a spatula or wooden spoon, mix until just combined. Be careful not to overmix. The batter will be thick and slightly fluffy. Let the batter sit for 5 minutes. This allows the coconut flour to absorb the moisture, which is crucial for the right texture.
Fill the Muffin Tin: Divide the batter evenly among the 12 prepared muffin cups. Fill them almost to the top, as these muffins don’t rise as dramatically as wheat-based muffins. You can use a cookie scoop or an ice cream scoop for even, clean filling.
Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes. The muffins are done when the tops are golden brown, feel firm to the touch, and a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs (not wet batter).
Cool: Remove the muffins from the oven and let them cool in the pan for about 10 minutes. Then, carefully transfer them to a wire rack to cool completely before glazing. This is important because if they are warm, the glaze will just melt right off.
Make the Glaze (Optional): While the muffins are cooling, make the glaze. In a small bowl, whisk together the powdered sweetener and 2 tablespoons of lemon juice. Add the remaining tablespoon of lemon juice, a little at a time, until you reach a thick but drizzling consistency. You want it to be fluid enough to drizzle but thick enough to set on the muffin.
Glaze and Serve: Once the muffins are completely cool, drizzle the glaze over the tops using a spoon or by transferring the glaze to a small zip-top bag and snipping off a tiny corner for a cleaner drizzle. The glaze will harden slightly as it sits.
Storage & Freezing Instructions
Storage: Store leftover muffins in an airtight container at room temperature for up to 2 days. For longer storage (up to a week), keep them in the refrigerator, as keto baked goods tend to spoil faster at room temperature due to the lack of preservatives.
Freezing: These muffins freeze beautifully! Place the cooled (and unglazed) muffins in a single layer in a freezer-safe bag or container. Freeze for up to 3 months. To thaw, leave them at room temperature or gently warm them in the microwave or oven. Glaze them after they have thawed.
