FAQs

Overcooking or too much almond flour are common culprits. Reduce microwave time by 10–15 seconds and measure flour with a spoon, not scoop, to avoid packing. A splash more almond milk (1 tsp) adds moisture without changing macros.

Yes, preheat to 350°F and bake in a greased ramekin for 12–15 minutes until a toothpick comes out clean. The texture will be slightly denser but still fluffy, perfect if you don’t trust microwaves or want to make multiples.

Use 1 tbsp melted butter or mashed avocado for fat and binding, or 2 tbsp Greek yogurt for tang. All keep it moist and keto-friendly; just adjust sweetness if yogurt is plain to balance the cinnamon flavor.

Use a mug at least 12 oz and fill batter only ⅔ full, it rises high. If it still bubbles over, pause microwave at 45 seconds, stir gently, then finish cooking, this releases air and prevents mess.
