This Blueberry Muffin Almond Flour Mug Cake is grain free (meaning it's also gluten free) and refined sugar free. You could even make it dairy-free by using dairy-free butter and milk. It's recently become my go-to fix when I need something sweet. It's so fluffy and delicious for only being almond flour!
This Blueberry Muffin Mug Cake makes the perfect breakfast, afternoon snack, or dessert. If you want to switch it up, you can swap the blueberries for raspberries, blackberries, chopped strawberries, or even chocolate chips.

Tips for Making the Best Almond Flour Mug Cake:
- Stir really well before microwaving to make sure there are no dry spots on the bottom or unincorporated egg. I prefer to use a mini whisk.
- Almond flour requires egg to rise—do not remove or substitute.
- Be sure to heat the mug cake until cooked through the middle. I recommend starting with 75-90 seconds, but my microwave takes a full 1 minute and 50 seconds.
- The blueberries will sink to the bottom of the mug. Add more to the top if you like.
- Swap the fruit with raspberries, blackberries, cherries, chopped strawberries, or chocolate chips to experiment with different flavor combinations. Wetter fruits, such as mango or peaches, may impact the way the cake cooks.

Ingredients for Blueberry Muffin Almond Flour Mug Cake:
- Finely Sifted Almond Flour. I use Blue Diamond—I get a big bag from Sam's Club.
- Baking powder
- Unsalted butter; use dairy-free butter for DF
- Milk; use a neutral plant-based milk such as almond, oat, etc. for DF
- Honey, or maple syrup
- Pure vanilla extract
- Salt
- Blueberries, fresh or frozen. I used frozen because it's what I had on hand. No need to thaw.

Blueberry Muffin Gluten Free Mug Cake Recipe:
- Melt the butter for 20-30 seconds (or until completely melted) in an oversized mug. Remove and set on a hot pad.
- Add the almond flour, baking powder, salt, milk, honey, and vanilla extract to the mug. Use a mini whisk or fork to stir really well, until no flour clumps remain.
- Add in the egg. Whisk vigorously until completely incorporated.
- Stir in the blueberries.
- Heat in the microwave for 60-90 seconds, or until completely set in the middle. **My microwave takes a full 1 minute and 50 seconds.
- Allow to cool 60 seconds before digging in. Enjoy warm! Optional: Top with more blueberries and/or whipped cream.

Equipment
You only need basic kitchen tools to make this Almond Flour Mug Cake. I recommend:
- An oversized mug between 12 to 15 oz. This just allows the cake enough room to rise. It tends to rise as it cooks, and then falls back down some into the mug.
- A mini whisk is ideal when making mug cakes since it really gets into the rounded edges.
- Pot holders are always necessary for mug cakes because the bottoms get real hot.
