INGREDIENTS SECTION
Here’s what you’ll need to make the most scrumptious Banana Nut Mug Cake:
-
2 very ripe bananas, mashed (about 2/3 to 3/4 cup, packed): Choose bananas that are heavily speckled brown for the sweetest, most flavorful cake. If you have frozen bananas, thaw and drain them before using.
-
1/4 cup light brown sugar, packed: This adds a caramel-like sweetness and depth of flavor to the cake.
-
2 tablespoons unsalted butter, melted: Always opt for a quality butter for the richest taste.
-
2 tablespoons whole milk: You could substitute with almond or oat milk if desired, but whole milk adds that wonderful creaminess.
-
1/2 teaspoon vanilla extract: Always use pure vanilla extract whenever possible for the best flavor.
-
3/4 cup all-purpose flour: All-purpose flour will give the right structure. You can use a gluten-free flour blend if needed.
-
1 teaspoon baking powder: This helps the cake rise beautifully.
-
1/2 teaspoon ground cinnamon: Warm and cozy, cinnamon elevates the flavors in your cake.
-
1/4 teaspoon kosher salt: A little salt enhances all the sweet flavors.
-
1/4 cup chopped walnuts, plus more for topping: Nuts give a delightful crunch to the soft, fluffy cake.
-
Caramel sauce, for drizzling: This adds an extra indulgent touch that you’ll love.
Prep Notes:
- Use room temperature butter for even mixing.
- If your bananas are not quite ripe enough, you can expedite the ripening process by placing them in a brown paper bag for a day or so.
STEP-BY-STEP INSTRUCTIONS
-
Prep the Mugs: Lightly spray two 12-ounce microwave-safe mugs with nonstick cooking spray. This ensures easy release once your cake is baked.
-
Mix the Wet Ingredients: In a medium bowl, combine the mashed bananas, brown sugar, melted butter, milk, and vanilla extract. Stir until smooth and combined.
-
Incorporate the Dry Ingredients: Add the flour, baking powder, cinnamon, and salt. Stir just until combined; do not overmix, or it could lead to a dense cake.
-
Add the Nuts: Fold in the chopped walnuts until evenly distributed throughout the batter. This gives fabulous texture to the cake.
-
Divide and Prepare: Divide the batter evenly between the two prepared mugs. Top with additional walnuts if desired for an extra crunch.
-
Microwave: Microwave each mug separately for 90 to 120 seconds on high. Start checking for doneness at 90 seconds; the center should be set but still moist. If it looks wet, continue microwaving in 10-second intervals until cooked through.
-
Serve Warm: Drizzle with caramel sauce before serving to take it to the next level of indulgence. Enjoy your warm Banana Nut Mug Cake with a smile!
Chef’s Tips:
- Avoid overmixing to keep your cake fluffy.
- Adjust microwave time depending on your microwave’s wattage—some may require a bit more or less time to cook.
- If your cake overflows, it’s okay! Just clean the mug, let it cool a bit, and enjoy.
EXPERT TIPS & TRICKS
-
Store: Your mugs can be stored in the fridge for up to 2 days if you happen to have leftovers (though I doubt it!). Just reheat in the microwave for about 15-30 seconds before enjoying.
-
Make Ahead: You can prepare the batter and store it in the fridge overnight for a quick dessert the next day; just remember to heat it a few seconds longer if they’re cold from the fridge.
-
Troubleshooting: If your cake doesn’t rise as expected, check wait on your baking powder—this can lose potency over time! Always check expiration dates on baking essentials.
SERVING SUGGESTIONS
Serve this delightful Banana Nut Mug Cake on its own, but you can also pair it with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat. It makes for a cozy dessert after dinner, perfect for those chilly nights snuggled up with a good book or a movie.
Alternatively, consider serving it with a warm cup of coffee or tea for a delightful afternoon snack that feels like a luxurious getaway.
VARIATIONS & SUBSTITUTIONS
-
Chocolate Chip Banana Nut Mug Cake: Swap out half of the walnuts for chocolate chips for a tempting twist.
