Start by gathering all the ingredients listed above. This will make the process smoother and more organized.
In your mixing bowl, combine the almond flour, coconut flour, baking powder, and salt. Use a fork or whisk to mix everything together until well combined.
In another bowl, mix together the water, lemon juice, almond butter, unsweetened applesauce, agave, and raw vanilla extract. Whisk until smooth.
Pour the wet mixture into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix; you want your cake to be light and fluffy.
Gently fold in the crumbled macaroons for that extra coconut flavor and texture.
Spoon the batter into your microwave-safe mug. Make sure to leave some space at the top, as the cake will rise during cooking.
Microwave on high for about 1 minute and 30 seconds, or until the cake has risen and is set in the middle. Cooking times may vary, so keep an eye on it!
Let the mug cake cool for a minute before digging in. You can enjoy it on its own or top it with a dollop of coconut yogurt or a scoop of your favorite dairy-free ice cream.
