Preheat the oven: Start by preheating your oven to 350°F (175°C) and lining a muffin pan with paper liners.
Combine Dry Ingredients: Stir together almond flour, coconut flour, baking powder and erythritol in a mixing bowl. Stir until evenly blended.
Make Wet Mixture: In a separate bowl, beat eggs, melted butter, almond milk and vanilla until smooth
Combine Mixtures: Slowly pour the wet ingredients into the dry mixture, mixing gently until a thick batter forms.
Add Strawberries: Fold in diced strawberries with a spatula, ensuring they’re evenly distributed.
Line Muffin Tin: Using an ice cream scoop, scoop the batter into a muffin tray, filling about 3/4 of the way up the liner.
Bake: Pop the tray in the oven and cook for 18–20 minutes, or until golden and firm.
Cool & Serve: Let stand for 5 minutes, then enjoy or refrigerate until ready to serve.
