How to Make Keto Blackberry Muffins

Just like regular carb-packed muffins, this low-carb counterpart is very simple to make.

You’ll combine butter and granulated erythritol in a bowl, then add in your other wet ingredients – eggs, lemon juice, lemon zest, vanilla, and coconut milk.

We use the full fat coconut milk from a can for this recipe.  If you don’t want to open a new can to make these, you can also substitute with cream, unsweetened almond milk, or regular milk (the last would create a slightly higher carb count).

Here’s a quick tip though – my wife actually likes to freeze leftover coconut milk in an ice cube tray, and then she puts all the ice cubes in a gallon size bag in the freezer to store.  Then she can pull out small amounts when she needs it for recipes!  (If you’re curious, 1 ice cube is equivalent to about 1 ounce, or about 2 tbsp.)  So if you do open up a can, there’s a trick for you to use to minimize food waste.

Moving on… After you’ve combined the wet ingredients, you’ll add the dry ones – almond flour, salt, and baking powder.  Then just fold in the blackberries, pour ‘em into a greased muffin pan, and bake for about 20 minutes.  Easy, right?

I like to make these in a 12-count muffin tin, and only fill up the batter about half-way to make small, snack-size muffins.  But you can also only fill about 6-8 of the tins for larger, bakery-style muffins.

Where to Get Ingredients

If you’ve been following the keto diet for a while, you’ve probably already got all these ingredients in your kitchen.  And if not, just about everything can likely be found at your supermarket these days!

The two ingredients that can be slightly more challenging to find are the almond flour (which is way more common these days than 5 years ago) and the erythritol.

If you have trouble finding either of these at your local grocery store, you can grab them on Amazon:

Are Blackberries Keto?

You might be wondering if you can eat sweet blackberries and still stay in ketosis.  For most people, small amounts of blackberries can fit on a keto diet, thanks to their high fiber content.  Because they are high fiber, their net carbs (total carbs minus fiber) are lower than many other fruits.

Similarly, other berries like raspberries and strawberries can also typically fit in small amounts.

With anything, it’s smart to check your ketone levels when adding new foods to the mix to be sure that it doesn’t affect your keto goals.

These muffins contain just a half cup of blackberries in the entire batch, so it’s unlikely that they’ll affect your blood sugar.  In fact, each muffin has just 1 net carb (7 total carb – 2 g fiber – 4 g erythritol = 1 net carb).

You could almost certainly boost the blackberry content safely if you wanted more of a fruity fix in these muffins, and still stay in a reasonable amount of net carbs for your snack.

Dietary Modifications

These blackberry muffins already fit a lot of dietary needs, since they’re naturally low carb and gluten free.

If you want to make these muffins dairy free, you can easily do so by substituting coconut oil for the butter.  They’ll just have a hint more coconut flavor.

I haven’t personally tried to make a vegan version of these muffins – but if you wanted to try, you’d need to substitute the butter and eggs.  The butter would simply be switched out for coconut oil, as mentioned above.  For the eggs, I’d recommend substituting the equivalent of two flax “eggs” (about 2 tbsp ground flax plus 5 tbsp hot water).  I can’t guarantee it will work, but if you try it out this way – be sure to let me know in the comments!

Enjoy these keto muffins, and if you try the recipe – I look forward to hearing your thoughts below.
