Ingredients

For the Keto Buttermilk:

  • ¼ cup warm water (110°F / 45°C) – intensity: low

  • ¼ cup heavy cream (full-fat, 36%+)

  • 1 tablespoon apple cider vinegar (or white vinegar)

For the Dry Mix:

  • 1 ½ cups superfine almond flour (not almond meal)

  • ¼ cup coconut flour (absorbs excess moisture)

  • 2 tablespoons psyllium husk powder (blonde, not black/dark)

  • 1 tablespoon baking powder (aluminum-free preferred)

  • ½ teaspoon fine sea salt

  • ¼ teaspoon garlic powder (optional, for savory biscuits)

  • ¼ teaspoon xanthan gum (optional but improves structure)

For the Fat & Binding:

  • 6 tablespoons (85g) cold unsalted butter, plus 1 tablespoon melted for brushing

  • 1 large egg + 1 large egg yolk (room temperature)

  • ¼ teaspoon liquid stevia or 1 tablespoon allulose (optional – for slightly sweet biscuits)


Step-by-Step Instructions (With Intensities Per Step)

Step 1: Make the “Buttermilk” (Intensity: Very Low)

In a small bowl or liquid measuring cup, combine the warm water, heavy cream, and apple cider vinegar. Stir gently. Let it sit for 5 minutes. It will thicken slightly and develop a tangy aroma. Do not skip the resting time—this acid activation is crucial for tenderness.

Step 2: Preheat & Prep (Intensity: Low)

Position a rack in the middle of your oven. Preheat to 375°F (190°C) . Line a baking sheet with parchment paper (not wax paper). Do not grease the paper; biscuits need traction to rise.

Step 3: Whisk Dry Ingredients (Intensity: Low)

In a large mixing bowl, whisk together the almond flour, coconut flour, psyllium husk powder, baking powder, salt, garlic powder (if using), and xanthan gum. Break up any clumps from the coconut flour using the back of a spoon or a fine-mesh sieve.

Step 4: Cut in the Cold Butter (Intensity: Medium – Physical)

Cut the 6 tablespoons of cold butter into ½-inch cubes. Add them to the dry mix. Using a pastry cutter (or two forks), work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces. Do not overmix. Some larger butter bits are good—they create steam pockets and flaky layers. This step takes about 4 minutes of steady cutting.

Step 5: Combine Wet Ingredients (Intensity: Low)

In a separate small bowl, beat the whole egg, egg yolk, and optional sweetener (if using) with a fork until frothy. Add the rested “buttermilk” mixture and stir to combine.

Step 6: Bring the Dough Together (Intensity: Medium)

Pour the wet mixture into the butter-flour mixture. Stir with a rubber spatula or wooden spoon until just combined. The dough will look shaggy and very sticky—this is normal. Keto biscuits don’t form a smooth ball like wheat dough. If the dough seems too wet to handle, let it rest for 2 minutes; the psyllium and coconut flour will absorb excess moisture.

Step 7: Shape the Biscuits (Intensity: Medium – Patience Required)

Lightly dampen your hands with water (this prevents sticking). Scoop the dough into 6 equal portions (about ¼ cup each). Gently roll each portion into a ball, then flatten slightly into a 1-inch thick disc. Do not overwork or try to knead the dough—that will make dense hockey pucks. Place biscuits 1 inch apart on the parchment-lined sheet.

Optional for classic fluted edges: Pat the entire dough into a 6×6-inch square, about 1 inch thick, on a piece of parchment. Use a round biscuit cutter (do NOT twist—press straight down and pull up). Re-form scraps once for a seventh biscuit.

Step 8: Brush and Bake (Intensity: Low)

Brush the tops of the biscuits with the remaining 1 tablespoon of melted butter. Bake for 14–16 minutes, rotating the pan halfway through. The biscuits are done when they are golden brown on top and feel firm to the touch. A toothpick inserted into the center should come out clean (not wet).

Step 9: The Critical Rest (Intensity: None – but mandatory)

Remove the baking sheet from the oven. Let the biscuits cool on the sheet for exactly 10 minutes. Do not skip this. Keto baked goods need time to set their internal structure. Cutting into them early will release steam and leave the center gummy.

Step 10: Serve (Intensity: Enjoyment)

Transfer to a wire rack or serve warm directly from the pan. Split with a fork and add butter, sugar-free jam, or keto gravy.


Chef’s Notes & Troubleshooting

  • Dough too sticky? Chill it for 10 minutes in the refrigerator before shaping. Cold dough is much easier to handle.

  • Biscuits spreading too much? Your butter may have been too warm. Next time, freeze the butter cubes for 10 minutes before cutting in.

  • No psyllium husk? Substitute 1 tablespoon ground flaxseed meal + 1 additional egg white, but texture will be denser.

  • Dairy-free version: Use coconut cream (not milk) for the buttermilk and vegan butter. The texture will be slightly softer.


Storage & Reheating

  • Room temperature: Store in an airtight container for up to 2 days.

  • Refrigerator: Up to 5 days. Reheat in a toaster oven or 300°F oven for 5 minutes.

  • Freezer: Wrap individually in plastic, then place in a freezer bag. Freeze for up to 3 months. Reheat from frozen at 325°F for 10–12 minutes.

  • Do not microwave – it makes keto biscuits rubbery.
