If you are looking for an easy, low-carb, nut-free, and keto-friendly bread recipe, you will love this 90-Second Low-Carb Bread! Made without almond flour, it is delicious served on its own, with some butter on top, or as a bun for a burger or sandwich!



  1. Melt butter in a shallow ceramic bowl, about 30-45 seconds.
  2. In a small mixing bowl, whisk together ground sunflower seed meal, ground flax seeds, baking powder, and salt. Pour dry ingredient mixture into melted butter and whisk together. Add egg and whisk again. Using a rubber spatula, spread mixture into even layer.
  3. Transfer bowl to microwave and microwave on high for 90 seconds.
  4. After cooking, allow to cool slightly before, using a knife, loosening edges of bread from bowl. Then, flip bowl upside down so bread can fall out. Using a serrated knife, slice into 2 pieces and then transfer slices to toaster to toast until golden brown. Serve on its own, spread butter on top, or use as a bun for a sandwich or burger.

Recipe Notes:

Butter Substitution: Coconut oil, ghee, or avocado oil will work here at a 1:1 substitution ratio. To make this is a dairy-free recipe, use coconut oil or avocado oil.

Ground Sunflower Seed Meal Substitution: You can substitute almond flour in at a 1:1 ratio.
