Step-by-Step Instructions for Making a Keto Brownie in a Mug

Preparing the Brownie Batter

Melt the Butter: Place the butter in a microwave-safe bowl and heat on high until melted but not overly hot.

Incorporate the Sweetener: Whisk in the powdered sweetener until it dissolves completely.

Add Egg and Vanilla: Carefully measure and add two teaspoons of egg and a dash of vanilla extract. Whisk until fully combined.

Mix Dry Ingredients: Stir in the almond flour, cocoa powder, and baking powder. Ensure all ingredients are well combined and free of clumps.

Adjust Consistency: The batter will be thick. Add one tablespoon of water or cold coffee to thin it out slightly.

Frequently Asked Questions

Can I Use Coconut Flour Instead of Almond Flour?

Coconut flour is not a suitable substitute due to its different absorbency. Sunflower seed flour is a 1:1 replacement for almond flour and works well.

Is There a Dairy-Free Option?

Yes! Substitute butter with coconut oil or another dairy-free alternative. For liquid oils like avocado oil, there’s no need to melt them first.

Can I Use a Different Sweetener?

You can, but the texture might change. Sweeteners like allulose can make the brownie more puffy and cake-like.
