4 tbsp all-purpose flour
3 tbsp brown sugar
1/8 tsp baking powder
Pinch fine salt
3 tbsp milk
1 tbsp melted butter
1 tbsp maple syrup

Nut prep: Toast walnuts in a dry skillet 2–3 minutes for extra crunch and aroma before chopping.

Step-by-Step

Mix dry. In a 12–14 oz microwave-safe mug, whisk flour, brown sugar, baking powder, and salt.
Stir in wet. Add milk, melted butter, and maple syrup; whisk until smooth.
Fold. Stir in chopped walnuts.
Microwave. Cook on HIGH 60–70 seconds until the top springs back lightly. Rest 1 minute and enjoy warm.

Maple intensity: Drizzle with a little extra pure maple syrup after cooking for a sticky bun vibe.
