FAQ: Microwave Keto Brownie
Can I bake this keto brownie in the oven instead of the microwave?
Yes! Simply preheat the oven to 350°F and prepare the recipe as written. Bake the brownie in oven-safe ramekins for 6-8 minutes or until it’s baked to you’re liking. Let it cool for a few minutes before serving.
Can I use regular flour instead of almond flour?
No, almond flour is keto-friendly and low-carb. Regular flour has a higher carb content and won’t work the same way in this recipe.
What’s the best way to store leftovers?
Since this is a single-serve recipe, it’s best enjoyed fresh. However, if you have leftovers, store them in an airtight container at room temperature for up to 1 day.
Can I make this brownie in advance?
Yes, you can mix the batter ahead of time and store it in the fridge for up to 24 hours. When ready to enjoy, simply microwave or bake it as instructed.
Why isn’t my brownie as moist as I’d like?
Be careful not to overcook it! Microwave times can vary depending on the wattage of your microwave. Start with 30 seconds, then increase in short intervals.
Can I double the recipe?
Yes! You can double the ingredients and split the batter into two ramekins or make a larger single-serve brownie in a bigger bowl. Cooking time may need slight adjustments.
