Ingredients

For the macaron shells:

• 1 cup almond flour (super-fine works best)
• 1 3/4 cups powdered monk fruit sweetener (or powdered allulose)
• 3 large egg whites, room temperature
• 1/4 tsp cream of tartar
• 1/4 tsp vanilla extract
• Pinch of salt
• Optional: natural food coloring

For the buttercream filling:

1–2 tbsp unsweetened coconut milk (or almond milk) to thin

1/2 cup dairy-free butter (or traditional butter if tolerated)

3/4 cup powdered monk fruit sweetener

1 tsp vanilla extract

Instructions

1. Make the Macaron Shells

1. Sift almond flour and powdered sweetener together to remove clumps.
2. In a separate bowl, beat egg whites with cream of tartar and salt until soft peaks form.
3. Add vanilla and beat until stiff peaks form.
4. Fold dry ingredients gently into the egg whites until smooth and glossy (the batter should flow like thick lava).
5. Transfer to a piping bag fitted with a round tip and pipe small circles onto a parchment-lined baking sheet.
6. Tap the tray gently to release air bubbles.
7. Let macarons rest at room temperature 30–60 minutes until a “skin” forms (they shouldn’t stick to your finger when lightly touched).
8. Bake at 300°F for 15–18 minutes until set and dry to the touch. Let cool completely.

2. Make the Buttercream

1. In a bowl, beat butter until fluffy.
2. Gradually add powdered sweetener.
3. Add vanilla and enough milk to reach desired consistency.

3. Assemble

• Pipe a small amount of buttercream onto the flat side of one cookie and sandwich with another.
• Chill briefly to set if desired.

Tips & Variations

• Nut-free? Use sunflower seed flour instead of almond flour (texture will vary slightly).
• Flavor twist: Add lemon zest to shells, or cocoa powder to the buttercream.
• Dairy-free butter: Miyoko’s, Earth Balance, or Country Crock Plant Butter all work great.

Storage Tips

• Fridge: Store assembled macarons in an airtight container for up to 5 days.
• Freezer: Freeze unfilled shells for up to 2 months. Fill after thawing for best texture.
