Step 1

Heat oven to 400°F. Lightly coat a 6-cup muffin pan with nonstick spray.

Step 2

In a bowl, combine cauliflower and 2 Tbsp water, cover, and microwave until very tender, about 10 minutes. Drain, then mash with a fork until smooth. Cool slightly, then place cauliflower in a clean kitchen towel and squeeze out as much water as possible.

Step 3

Return cauliflower to bowl, add almond flour, baking powder, and salt, and stir well to combine. Mix in Cheddar, egg whites, and butter until incorporated, then fold in bacon and chives.

Step 4

Using hands, form dough into 6 balls and place in prepared pan, pressing to flatten. Bake until tops are golden brown, 23 to 25 minutes. Let cool in pan 5 minutes. If necessary, run thin-bladed knife around sides of biscuits before inverting onto wire rack.
