5-Minute Keto Microwave Biscuit (Single Serving)

Breakfast

March 10, 2026

What if I told you that a warm, freshly made biscuit could be yours in less than five minutes? It’s true! This incredibly easy and versatile microwave biscuit recipe has become my latest obsession. It’s the perfect single-serving solution for a quick breakfast or snack. My favorite way to enjoy it is slathered with mayonnaise and piled high with avocado, bacon, and tomato for the ultimate quick sandwich. A quick tip: the size of your mug matters! I prefer a wide-based mug to get a broader biscuit that’s perfect for slicing and stuffing. Since every microwave has its own personality, start with the minimum cook time and add more if needed. After a try or two, you’ll be a microwave biscuit pro!

Ingredients

• ¼ cup / 28 g blanched almond flour
• 1 tablespoon coconut flour
• ½ teaspoon baking powder
• ¼ teaspoon finely ground sea salt
• 1 large egg
• 1 tablespoon softened coconut oil or ghee
• 1 teaspoon apple cider vinegar

Instructions

1. Combine all in a microwave-safe mug (at least 2 inches / 5 cm wide at the base). Mix with a fork until the batter is smooth and fully incorporated, then flatten the top with the back of a spoon.
2. Place the mug in the microwave and cook on high for 1 minute and 30 seconds.
3. Carefully remove the mug and test for doneness by inserting a toothpick into the center. If it comes out clean, it’s ready. If wet batter clings to the toothpick, microwave for an additional 15 to 30 seconds.
4. Invert the mug over a plate and give it a gentle shake to release the biscuit. Serve warm, slathered with your favorite fat like butter or coconut oil if desired.
