Almond flour makes waffles that are crispy, nutty, and completely grain-free. Add butter and these low carb waffles become a keto brunch highlight.
Preheat your waffle iron on medium-high and lightly grease the plates with a nonstick spray or a little butter.
In a large mixing bowl, whisk together the almond flour, baking powder, salt, and erythritol until the ingredients are evenly combined.
In another bowl, beat the eggs thoroughly, then add melted butter, almond milk, and vanilla extract, mixing until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined — do not overmix; let the batter rest for 2 minutes to hydrate.
Ladle enough batter to just cover the bottom of the waffle iron (do not overfill) and cook with the lid closed for about 3–4 minutes, until the waffles are golden and crisp at the edges.
Carefully remove the waffle with a fork or silicone spatula and repeat with the remaining batter, adjusting cook time as needed to avoid burning.
