Cinnamon Nut Swirl Mug Cake

Nancy Wheeler

Report

This Cinnamon Nut Swirl Mug Cake is a quick single-serving dessert made directly in a mug using simple pantry ingredients. The batter combines flour, brown sugar, baking powder, cinnamon, and chopped pecans folded with melted butter and milk for a moist, tender crumb. A cinnamon-butter swirl is folded into the batter before microwaving, creating ribbons of cinnamon sweetness throughout. A simple powdered sugar glaze finishes the cake, balancing the warm spice and nutty flavors.

Description

The mug cake batter includes basic dry ingredients enhanced by cinnamon and chopped pecans, offering texture and a nutty touch. Melted butter and milk create moisture, resulting in a quick-cooked cake with a soft and slightly dense texture. The cinnamon butter mixture is drizzled and partially mixed in to distribute pockets of cinnamon sweetness and buttery richness throughout the cake. Cooking in the microwave allows the cake to rise and set within a minute, providing an immediate warm treat.

After cooking, a light glaze made from powdered sugar and milk is added for a subtle sweetness and slight moisture. This cake is suitable for a fast dessert or snack without needing an oven and yields a portion sized for one, minimizing waste. The options to substitute walnuts for pecans offer simple flavor adjustments.

Instructions

Keep Screen Awake

In a small mug (about 1 cup volume), stir together the dry ingredients for the mug cake batter: flour, brown sugar, baking powder, salt, cinnamon, and chopped pecans.
Add the melted butter and milk to the dry ingredients in the mug and stir until a thick batter forms.
In a separate small bowl or mug, melt the butter for the cinnamon butter swirl (about 15 seconds in the microwave). Stir the brown sugar and cinnamon into the melted butter.
Drizzle the cinnamon butter swirl over the mug cake batter, then gently fold them together until they are only about half mixed. There should be thick ribbons of the cinnamon butter swirl throughout the batter.
Microwave the mug cake for 45-55 seconds (for a 1100 watt microwave, cooking time will vary with microwave wattage). The mug cake will create quite a bit of steam as it cooks, so don't be alarmed. Let the mug cake cool for 1-2 minutes.
While the mug cake is cooling, stir together the powdered sugar and milk for the icing, using the same small bowl used for the cinnamon butter swirl. The residual cinnamon in the bowl will flavor the icing.
Drizzle the icing over the mug cake and enjoy while it is still warm.
