Step 1To make the Keto Blender Vanilla Muffins, preheat the oven to 160 °C/ 320 °F (fan assisted), or 180 °C/ 355 °F (conventional). Place everything for the muffins in blender, wet ingredients first. Process until smooth. If any of the dry ingredients get stuck on the sides, use a spatula to scrape them and process again.
