10-Minute Gooey Peach Mug Cake

10-Minute Gooey Peach Mug Cake…doesn’t that just say it all?  This peachy dessert takes only 10 minutes to make, it’s filled with peaches and cinnamon-spiced cake, and has a beautifully caramelized brown sugar topping.

It’s made in the microwave and literally takes minutes.  The idea of an individual mug cake is brilliant…it’s the perfect snack when it’s just you and you’ve got the urge to indulge.  It’s also perfect when there are more snacky people around..just double or triple the recipe!

Layer some peach slices, brown sugar and butter in the bottom of a mug.  I used a 10-ounce mug, but you might want something a tiny bit larger as I got a little over-run.  There will be less cleanup if you use a bigger mug.

Since each microwave has a different wattage, you’ll want to watch to see how long it takes to melt the butter and soften the peaches, but it shouldn’t take more than one minute.

The cake batter is a combination of melted butter, brown sugar, egg and vanilla.  Once whisked, add flour, rolled oats, baking powder, and salt, and stir until it’s just combined.

Pour the batter over the peaches that are already in the mug and place the remaining peaches on top, sprinkle some more brown sugar, butter and cinnamon over top and pop it back in the microwave for 2 minutes.

I love eating this with ice cream, but it’s your world…you do you!

      Tonight I made the Gooey Peach mug for my son’s birthday. We all loved it. A nice change from from birthday cake. It is so yummy. I also made the Buttery corn chicken dinner. One of our new favorites for sure. We all loved it. I served it atop Linquini. It is something I will make for a dinner party . Besides delicious, the presentation was beautiful.
