Ingredients & Notes
See the recipe card for full information on ingredients and quantities.
You only need a few simple ingredients to make this high-protein single-serve dessert.

- Egg: Acts as a binder, providing moisture and structure to the cake while adding protein. If you can, use one at room temperature.
- Olive Oil: A healthy fat that keeps the cake moist and adds richness.
- Maple Syrup: A natural sweetener that brings out the best flavors and adds just the right touch of sweetness.
- Lemon Juice (optional): A splash of citrus enhances the freshness of the blueberries.
- Almond Flour: A gluten-free, low-carb flour that gives the mug cake a tender crumb and nutty flavor, similar to my Almond Flour Banana Cookies with Chocolate Chips.
- Collagen Powder: Boosts the protein content and supports skin, hair, and joints. Use unsweetened and flavor-free powder.
- Baking Powder: Helps the cake rise for a fluffy texture.
- Fresh Blueberries: Add natural sweetness, antioxidants, and flavor.
How To Make It
See the full recipe with measurements in the recipe card.
It's the best almond flour mug cake with those delicious sweet blueberries bleeding into a soft spongy cake. This dessert can be yours with a few clean ingredients and some minutes to spare.

Step One (Picture 1 above) - In a microwave-safe mug (preferably a 12-ounce coffee or latte cup), beat the egg with a small whisk or fork. Stir in the rest of the wet ingredients.
Step Two (Picture 2 above) - Whisk in the dry ingredients until well combined and you get a yellow cake batter.
Step Three (Picture 3 above) - Microwave for about 2 minutes and 40 seconds. The cake should rise and firm up. Adjust cooking time based on your microwave oven. Let the cake sit for a few seconds (it can be hot!). Garnish and enjoy!
Top Tips
- Microwave Times Vary: My sweet spot is 2 minutes and 40 seconds in my microwave on high power. Different microwaves heat differently. Start checking at the 2-minute mark to ensure your cake is perfectly set.
- Use a Microwave-Safe Coffee Mug: Be sure to use a mug that can hold at least 12 ounces to give your cake batter enough room to rise, and place it in the center of the microwave.
- Check the Center: You can check the center with a butter knife to check doneness.
- Gooey Cake: If you want a more moist and gooey cake, reduce the cooking time to 2 minutes.
- Extra Flavor: Garnish with a few teaspoons of coconut yogurt and extra blueberries for that extra refreshing, creamy bite.

Storage
This Almond Flour Mug Cake is best enjoyed immediately, as it’s a single-serve dessert.
However, if you have leftovers, store them in an airtight container in the fridge for up to 1 day. Reheat in the microwave for 20-30 seconds for the best texture.
Recipe FAQs
While coconut flour can work, it’s much more absorbent than almond flour, so you’d need to adjust the liquid ratio. For best results, stick with almond flour.
Although not tested, I imagine you can replace the regular collagen powder with a chocolate-flavored one to make a blueberry chocolate mug cake recipe.
