90-Second Irresistible Blueberry Muffin in a Mug

Mug cakes have a special place in my heart because I tend to make them late night when I have some silence and need a little something sweet to finish off my day.

I went through a major 1-Min Quickie Gooey Chocolate Mug Cake phase (can you blame me?!) and have since went down a serious rabbit hole of all microwaveable mug recipes. I’m not even sorry about it, this has been a delicious expedition.

While I’ve focused a lot on cakes and cookies in my mugs (3-Min Moist & Fluffy Microwave Banana Mug Cake and 1-Min Deep Dish Microwave Chocolate Chip Cookie), I knew the fluffy nature of mug cakes lended themselves to a perfect muffin.

And so began the testing for the perfect muffin in a mug and microwaved for just 90 seconds.

Ingredients for Blueberry Muffin in a Mug

Almond Flour.

Almond flour is naturally gluten-free and adds a nutty flavor, moisture, and a tender crumb to the muffins.

Coconut Flour.

Coconut flour is highly absorbent and helps bind the muffin batter. It brings a subtle coconut flavor and adds a slightly denser texture to the muffins.

Egg.

Eggs act as a binder and provide structure to the muffins. They also contribute moisture and help the muffins rise during baking. Feel free to sub in your favorite store-bought egg replacer if needed.

Honey.

Honey adds sweetness, moisture and flavor to the muffins. If you don’t have honey, agave nectar or maple syrup are a great sub!

Almond Milk.

Almond milk helps create a smooth consistency and ensures the muffins are not too dry. I’m using almond milk here but dairy milk or oat milk are also great options!

Salted Butter.

Melted butter adds richness and flavor to the muffins. The salted butter provides a balanced contrast to the sweetness of the honey and blueberries.

Vanilla Extract.

Vanilla extract complements the other ingredients and contributes to the comforting taste of baked goods.

Baking Powder.

Baking powder is a leavening agent that helps the muffins rise and become light and fluffy. It creates air pockets in the batter, resulting in a fluffy, happy muffin.

Cinnamon.

Cinnamon adds warmth and depth to the muffins. It pairs wonderfully with the sweetness of the honey and the juicness of the blueberries.

Blueberries.

Blueberries are the star of blueberry muffins, providing bursts of natural sweetness and a juicy texture. Feel free to get creative with different berries if you want!

Choose the Right Mug for your Muffin

Make sure to select a microwave-safe mug with high sides to prevent overflow during cooking. The batter will rise as it cooks, so a tall mug is perfect for containing it.

How to Make Muffin in a Mug with Blueberries

Mixing the Ingredients:

In a mixing bowl, combine the ingredients (except for the blueberries). Whisk the ingredients together until well combined.

Then, add the blueberries to the bowl. Gently fold in the blueberries, distributing them evenly throughout the batter.

Pouring the Batter:

Once the batter is well-mixed and consistent, carefully pour it into the chosen microwave-safe mug. Fill the mug about halfway to two-thirds full to allow for expansion as the muffin cooks.

Microwave your Muffin in a Mug:

Place the mug in the microwave. Set the microwave timer for 90 seconds as a starting point. The cooking time can vary based on the wattage of your microwave and the specific recipe, so some microwaves may require up to 2 minutes for the muffin to fully set.

Keep an eye on the muffin as it cooks. It should rise and become firm in texture. If the muffin looks undercooked after the initial time, continue microwaving in short intervals (e.g., 15-30 seconds) until it’s fully cooked and no longer wet in the center.

Serve and Enjoy!

Once the muffin is cooked, carefully remove the mug from the microwave (be cautious, as it will be hot).

Allow the muffin to cool for a minute or so before digging in!

Variations to Try

Fruit Swirl. Instead of folding in whole blueberries, create a fruit swirl by adding a spoonful of blueberry jam or a fruit compote to the batter before microwaving. Swirl it gently with a toothpick for a burst of fruitiness throughout the muffin.

Nutty Delight. Add chopped nuts such as almonds, walnuts, or pecans to the batter for added crunch and flavor. Nuts can enhance the texture and offer a delightful contrast to the soft muffin.

Chocolate Indulgence. For a chocolate twist, mix in chocolate chips or chunks to the batter.

Citrus Zest. Incorporate the zest of lemon or orange into the batter for a refreshing citrus flavor that complements the blueberries. This can add a bright and tangy note to your muffin.

Cream Cheese Swirl. Create a cream cheese swirl by blending softened cream cheese with a touch of sweetener and swirling it into the batter before microwaving. This adds a creamy and tangy element to your muffin that complements the juicy blueberries nicely.

How to Store Leftover Muffin in a Mug

Immediate Consumption. Mug cakes are typically best enjoyed immediately after they are cooked. This is when they are their best: soft, moist, and at their peak in terms of taste and texture. If possible, try to consume your mug cake shortly after it’s made.

Refrigeration. If you have leftover mug cake, you can store it in the refrigerator for a short period. Place the mug cake in an airtight container or cover the mug with plastic wrap. Keep in mind that refrigeration can cause the cake to become denser and slightly less moist compared to when it’s fresh.
