Microwave mug brownie

Ingredients
2 tablespoon butter, melted and cooled
1/4 cup all-purpose flour
1/4 cup brown sugar
1 1/2 tablespoon milk
1/4 teaspoon espresso powder
1/2 teaspoon vanilla extract
1 large egg
Salt
2 tablespoon pecans, toasted and chopped, optional
2 tablespoon chocolate chips, optional

Instructions:

Sift the flour and cocoa powder together over a bowl.

In another bowl, whisk the melted butter, brown sugar, espresso powder, milk, egg, vanilla and a very small pinch of salt together until blended then pour into the bowl with sifted flour and cocoa powder. Whisk until combined. Gently stir in pecans and chocolate chips then carefully pour into the mug.

Clean any drips around the edges of the mug then microwave for 1 minute (for lava cake) to 1:30 (for fully cooked). Don’t overcook or it will dry out.
