Satisfy your carb cravings without derailing your health goals by making this easy, quick recipe for delicious, gluten-free muffins!

I’m a Midwesterner, born and bred. That means I am genetically predisposed to a penchant for baked goods. Maybe that’s fuzzy science, but it certainly feels true. So when my partner embarked on a low-carb journey, I thought we’d have problems—I imagined sneaking to the bakery behind his back to binge on illicit bread, muffins, and cookies.
Then I found this low-carb blackberry muffins recipe. I was so happy to be able to bake something my partner and I could enjoy together! I’ve baked from scratch since I was a teenager, but I’d never used almond flour or sugar substitutes before. I was relieved to find both almond flour and granulated erythritol right there on the shelf of my local grocery store! And making this recipe was just as straightforward as any other muffin recipe. The batter was a little denser than I expected, but the finished product did not disappoint.
Our apartment filled with enticing aromas as the muffins baked—I could hardly stand waiting 15 minutes for them to cool before trying one. They delivered a delightfully chewy texture and subtle sweetness. The lemon juice and zest added a bright freshness to the vanilla notes in the batter, and the blackberries punctuated every bite with tart freshness. These muffins will definitely satisfy your carb cravings. I now make them at least once a week. They might have saved our relationship, or at least made it sweeter!

How berries fit with a low-carb lifestyle
Blackberries are a go-to fruit for anyone following a low-carb or ketogenic lifestyle. That’s largely because of their impressive balance of low carbs and high fiber. With about 10 grams of total carbs and nearly 5 grams of fiber per 100-gram serving, blackberries stand out compared to many other fruits, like apples and bananas, that pack much more sugar and less fiber per serving. This generous fiber content means that the net carbs—aka those that impact blood sugar—remain quite low for blackberries, making it easier to incorporate them into keto baked goods or snacks without exceeding daily carb goals.
When sizing up other berries, blackberries share center stage with raspberries, which offer a nearly identical carb-to-fiber ratio and a similar tangy bite. Strawberries and blueberries are close contenders—but strawberries contain slightly more carbs, and blueberries have the most total carbs among the common berries. Beyond their carb profile, all berries deliver a wealth of vitamins like C and K, along with manganese and a rainbow of natural pigments called polyphenols. These nutrients bring great flavor and vibrant color to recipes like this one while supporting a nutrient-rich, balanced approach to low-carb eating.
How do I store leftovers?
Once your blackberry muffins have completely cooled, store them in an airtight container, separating layers with parchment paper. Don’t leave them at room temp for longer than 1 or 2 days, as almond flour-based baked goods retain more moisture than traditional ones and will spoil more quickly. But they’ll keep in the fridge for up to 7 days. You can also freeze them for up to 3 months. Thaw overnight in the fridge or at room temp for a few hours—or warm them in the microwave for 20-30 seconds to revive that fresh-baked texture.

- 1 1/2 cups almond flour
- 1/4 teaspoon salt
- 1 teaspoon baking powder
- 1/2 cup blackberries chopped roughly
Instructions
- Preheat the oven to 350°F. Prepare a muffin pan with liners or a coating of nonstick spray.
- In a large mixing bowl, combine the softened butter and granulated erythritol. Mix in the eggs, lemon juice, lemon zest, vanilla, and coconut milk.
- In a separate bowl, combine the almond flour, salt, and baking powder. Add the dry ingredients to the wet mixture and stir until combined. Fold in the blackberries.

- Bake until a knife inserted into the center of a muffin pulls out clean, about 20 minutes.
