If you’re a fan of the popular Starbucks lemon loaf, these Keto Lemon Poppyseed Muffins are sure to be your next addiction! Incredibly fluffy, moist, and with the perfect amount of citrusy zing, they’re secretly more cake than muffin. But, at just 1g of sugar per serving, this keto, gluten-free and paleo treat is a healthy option as a dessert, snack or even breakfast!

Recipe options included for those following a vegan diet, as well as suggested modifications for an extra serving of fruit.

How to make Keto Lemon Poppyseed Muffins

These keto lemon poppyseed muffins can be thrown together quickly and easily using basic pantry staples. I recommend using a muffin tray with silicone muffin liners or just a silicone muffin tray. Cooking times will vary depending on your oven so watch the muffins closely after 18 minutes and remove when the tops start to brown. For me, that means a bake time of about 25 minutes.

If you prefer a drizzled glaze rather than a fully-frosted top, you can cut the glaze recipe in half. Using a spoon, pour a small amount of glaze over each muffin in a zig-zag pattern and leave them to dry. Alternatively, for fully frosted tops, make the glaze as written below and spoon 1-2 teaspoons onto the centre of each muffin. Let the glaze drip down the sides as pictured.

Inspiration for the Recipe

One of Starbucks most delicious treats is their famous glazed lemon loaf. Unfortunately, one slice has a whopping 42g of sugar, which is more than the recommended maximum daily intake for both men (36g) and women (25g). By way of comparison, one 12 oz can of coke contains 39g of sugar.

Lemon desserts have always appealed to me because they are light, refreshing and perfectly tangy. Plus, the combination of sweet with sour makes my tastebuds do a happy dance. So, it was a no-brainer for me to try to create a keto version of Starbucks’ lemony treat!

These lemon poppyseed muffins have just 1g of sugar per serving and 173 calories compared to 42g of sugar and 470 calories for a single slice of Starbucks lemon loaf.

Modifications and Substitutions

If you follow a vegan diet, substitute the eggs for flax eggs instead. For every egg you’re replacing, mix 1 tablespoon of flaxseed meal and 2.5 tablespoons of water. Check out Minimalist Baker’s How to Make a Flax Egg for more detailed instructions. You’ll also need to substitute the butter in the icing by using 1 tablespoon of melted coconut oil instead.

For an extra pop of colour and deliciousness, try adding 1/4 – 1/2 cup of fresh blueberries to the batter. Instructions and cooking times will remain the same.

You can control the strength of the lemony taste in this recipe by adding more or less juice and zest to the muffin mix and glaze. If you prefer a more mild lemon flavour, cut the amount of lemon in half. You can also achieve a more mild flavour by drizzling the glaze on top sparingly rather than coating the tops entirely.

Finally, you can try making these lemon poppyseed muffins as a loaf instead. Simply pour the batter into a greased or lined 9×5 loaf pan and bake at 375 degrees for about 45 minutes, or until the top has started to brown and a toothpick inserted in the middle comes out clean.

Can you freeze Lemon Poppyseed Muffins?

Yes! I experimented with freezing a few of these muffins and determined that freezing and thawing had no impact on the texture or taste.

I recommend wrapping each muffin individually in plastic wrap or tinfoil before placing in the freezer. Freezing the muffins individually makes it easier to thaw the exact number you want rather than an entire batch at once. For best results, take the muffins out of the freezer the night before and let them thaw in the fridge overnight.

    I’m not familiar with “Swerve” sweetener, but it sounds like you use it as you would regular granulated sugar (or powdered sugar for the icing); one to one?
