Related Keto Baking Questions

Are Blueberries Keto Friendly?

Blueberries can be keto-friendly in small quantities. Compared to most popular fruits, fresh blueberries are relatively low sugar and high fiber, with 14g of carbs per 100g serving. But I know you’re probably thinking that’s still pretty carb and sugar-dense for keto. I agree – and as a Type 1 Diabetic eating low carb, I don’t personally choose to eat a full serving of fruit at once – even berries!

The beauty of this low carb blueberry muffin recipe is that we’re spreading those blueberry carbs throughout 12 muffins. In fact, in each muffin you’re really only eating 1 Tbsp of wild blueberries!

And that tablespoon of wild blueberries adds just 1g of carbs to each muffin (1.3g if you’re using regular blueberries), while still adding a TON of flavor.

How many carbs are in a homemade blueberry muffin?

A medium-size homemade blueberry muffin with regular granulated sugar and all-purpose flour usually has around 48 carbs (!!!). But don’t worry keto friend, my low carb blueberry muffin recipe only contains around 3 net carbs per muffin (and 5.9 total carbs).

Can I use frozen blueberries in muffins?

You can definitely use frozen blueberries in these keto blueberry muffins. Here’s what you should know:

  • Frozen blueberries will make your batter cold and you’ll probably need to increase your baking time (but keep your oven temp the same – don’t be tempted to turn it up!).
  • Wild blueberries are readily available in the freezer section. These tiny berries are way more flavorful than your standard blueberry and slightly lower in sugar.
  • Don’t defrost the frozen blueberries before adding them to your muffin batter. If you do, the berries will release their juices as they defrost, and that extra liquid will throw off the recipe while also turning your batter an unappetizing color.

Can you eat coconut flour on keto?

You can eat coconut flour on a keto diet, in fact, it’s my #1 choice for keto and low carb baking. That’s because coconut flour is extremely absorbent and high fiber, so most recipes require a whole lot less of it than regular all-purpose flour. 

Coconut flour is also much lower calorie than almond flour. And while calories aren’t everything, I don’t really want to waste mine on an unnatural amount of ground-up almonds. I mean, I could fit an entire extra coconut flour treat into my macros instead!

I only use and recommend Bob’s Red Mill Coconut Flour. Different brands of coconut flour vary in their absorbency, so it’s always best to use the brand the recipe was created with.  I’ve always gotten the best results with Bob’s Red Mill. It also happens to be the brand of coconut flour most commonly used by recipe bloggers, so it’s likely to give you the most consistent outcomes across the board.

Do You Have To Spray Cupcake And Muffin Liners?

You shouldn’t have to spray cupcake and baking liners, but I’ve found that a lot of inexpensive liners and decorative liners will stick. And baking with something sticky or sweet like the blueberries in these low carb muffins only makes the sticking worse!

So what do I do about cupcake liners sticking? If You Care’s Baking Cups are the only cupcake and muffin liners that never stick for me. For a regular muffin tin, you’ll want the large size cups. You can click here to buy the same ones I use on Amazon.

Can You Make These Keto Blueberry Muffins Dairy-Free?

What if you want the best tasting low carb blueberry muffins that are also dairy-free? Simply substitute coconut oil in place of the butter, and coconut milk in place of the half and half.

Can You Freeze Keto Blueberry Muffins?

You can definitely freeze these keto blueberry muffins! I know many BIK readers are the only low carbers in their household, and we definitely don’t want those keto baked goods to mold and go to waste. Freezing baked goods is a fantastic way to make them last.

Simply put the baked and cooled muffins in a glass or plastic storage container and freeze. They only need around 30 seconds in a microwave to defrost.
