Ingredients

Here’s what you’ll need to make this delightful mug cake:

• 1 ripe medium banana: Look for one with a few brown spots for the best sweetness and mashability.
• 2 tablespoons creamy peanut butter: Natural or regular creamy peanut butter works best.
• 1 large egg: This helps bind the cake and makes it fluffy.
• 2 tablespoons milk: Any kind of milk works—dairy or non-dairy.
• 1 tablespoon maple syrup or honey: Adjust to your sweetness preference.
• 3 tablespoons all-purpose flour: You can also use oat flour or whole wheat flour for a healthier twist.
• 1/4 teaspoon baking powder: Essential for a light and airy texture.
• 1/2 teaspoon vanilla extract: Adds a lovely depth of flavor.
• Pinch of salt: Balances the sweetness and enhances flavors.
• Optional: 1 tablespoon mini chocolate chips: A delightful addition for chocolate lovers!

Kitchen Equipment

• One large microwave-safe mug (about 12-16 oz)
• Fork or small whisk
• Measuring spoons

Step-by-Step Instructions

Let’s get cooking! It’s so quick, you’ll be amazed.

1. Mash the Banana: In your microwave-safe mug, mash the ripe banana with a fork until mostly smooth. A few small lumps are perfectly fine!
2. Add Wet Ingredients: Stir in the peanut butter, egg, milk, maple syrup (or honey), and vanilla extract. Mix well until everything is fully combined and smooth.
3. Add Dry Ingredients: Sprinkle in the flour, baking powder, and a pinch of salt. If using, now is the time to add your mini chocolate chips.
4. Mix Gently: Stir with your fork until just combined. Be careful not to overmix; a few streaks of flour are okay. Overmixing can make your mug cake tough.
5. Microwave: Place the mug in the microwave and cook on high for 1 to 2 minutes. Cooking time can vary depending on your microwave’s wattage. Start with 90 seconds and add 15-second intervals until the cake is set in the center and springs back when lightly touched. It might puff up quite a bit!
6. Cool and Enjoy: Carefully remove the hot mug from the microwave. Let the mug cake cool for a minute or two before digging in. It will be very hot!

Expert Tips

• Don’t Overmix: Just like with any cake, overmixing develops the gluten in the flour, leading to a tougher texture. Mix until just combined.
• Know Your Microwave: Microwave wattages vary widely. Start with the lower cooking time and add small increments until the cake is cooked through. If it’s too dry, you’ve overcooked it.
• Ripe Bananas are Key: The riper the banana, the sweeter and more flavorful your mug cake will be. It also mashes much easier.
• Grease Your Mug (Optional): If you plan to invert your mug cake onto a plate, a light spray of cooking oil in the mug can help prevent sticking.
• Topping Ideas: A sprinkle of cinnamon, a drizzle of extra peanut butter, a spoonful of Greek yogurt, or a few fresh banana slices make wonderful toppings.

Variations

Get creative with your mug cake!

• Chocolate Peanut Butter Mug Cake: Add 1 tablespoon of unsweetened cocoa powder along with the flour for a rich chocolate base.
• Protein Mug Cake: Substitute 1 tablespoon of flour with 1 tablespoon of your favorite vanilla or unflavored protein powder for an extra boost.
• Vegan Mug Cake: Use a flax egg (1 tablespoon ground flaxseed meal + 2.5 tablespoons water, let sit 5 minutes) instead of a regular egg, and ensure you use plant-based milk and maple syrup.
• Gluten-Free Mug Cake: Easily swap the all-purpose flour for a 1:1 gluten-free baking blend.
• Nut-Free Version: If you have nut allergies, swap the peanut butter for sunflower seed butter (SunButter).

What to Serve With

This mug cake is fantastic on its own, but here are some ideas to make it even more special:

• A dollop of Greek yogurt or a scoop of vanilla ice cream.
• A generous drizzle of extra peanut butter or a sprinkle of chopped nuts.
• Freshly sliced bananas or berries.
• A tall glass of cold milk or a warm cup of coffee or tea.

Storage

Mug cakes are definitely best enjoyed fresh and warm straight from the microwave. However, if you happen to have a bite or two left:

• Refrigerator: Cover the mug tightly with plastic wrap or transfer the cake to an airtight container. It will keep in the refrigerator for up to 1 day.
• Freezer: Freezing is not recommended for mug cakes, as the texture tends to become dry and less appealing upon reheating.
• Reheating: If refrigerating, reheat in the microwave for 15-30 seconds until warmed through. Be careful not to overcook, or it will dry out.

Frequently Asked Questions

Can I make this ahead of time?

While best fresh, you can mix the dry ingredients ahead of time. However, the wet ingredients (especially the banana and egg) should be mixed just before microwaving for the best results.

What kind of mug should I use?

Use a sturdy, microwave-safe ceramic mug, ideally 12-16 ounces, to prevent overflow as the cake rises.

Can I bake this in a regular oven?

This recipe is designed for the microwave. If you wish to bake it, transfer the batter to a small ramekin and bake at 350°F (175°C) for 15-20 minutes, or until a toothpick inserted comes out clean. Oven results will differ slightly in texture.

Can I use frozen bananas?

Yes, just thaw the banana first and drain any excess liquid before mashing it. Ensure it’s very ripe for sweetness.

Is this recipe really healthy?

It’s a healthier alternative to many traditional desserts, packed with good fats from peanut butter and natural sweetness from banana. It’s also a single serving, which helps with portion control!

Why did my mug cake turn out dry or rubbery?

This usually happens from overcooking. Microwaves vary, so start with less time and add more in small increments until it’s just set. Overmixing the batter can also contribute to a tough texture.

Can I double the recipe?

It’s best to make two separate mug cakes rather than doubling the recipe in one mug, as cooking times and consistency will be affected in a larger volume.
