Ingredients Breakdown

Understanding the role of each ingredient helps you appreciate why this cake works so well. Almond flour serves as the base, providing a nutty richness while keeping carbs low. Eggs bind everything together and add structure. Greek yogurt brings moisture and a slight tang, complementing the lemon. Fresh lemon zest and juice infuse the cake with bright citrus notes, while blueberries add juicy sweetness and a pop of color. A touch of granulated sweetener (like erythritol or monk fruit) keeps it low-carb without sacrificing taste. Finally, baking powder ensures a light, fluffy crumb.

How to Make Blueberry Lemon Cake (Low Carb)

Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper for easy removal. In a large bowl, whisk together 2 cups of almond flour, 1/3 cup of granulated sweetener, 1 1/2 teaspoons of baking powder, and a pinch of salt. In another bowl, beat 3 eggs until frothy, then mix in 1/4 cup of melted butter (or coconut oil), 1/4 cup of Greek yogurt, the zest of 1 lemon, and 2 tablespoons of fresh lemon juice. Gradually fold the wet ingredients into the dry until just combined. Gently stir in 1/2 cup of fresh blueberries, reserving a few for the top. Pour the batter into the prepared pan, scatter the remaining blueberries on top, and bake for 30-35 minutes, or until a toothpick comes out clean. Let it cool before slicing.

Pro Tips for the Best Results

For an extra-moist cake, don’t overmix the batter—just stir until the ingredients are incorporated. To prevent the blueberries from sinking, toss them in a bit of almond flour before folding them in. If you prefer a more intense lemon flavor, add an extra teaspoon of zest or a splash of lemon extract. For a golden, slightly crisp top, brush the baked cake with a little melted butter as soon as it comes out of the oven. And if you’re using frozen blueberries, keep them frozen until the last moment to avoid excess moisture.

Variations and Substitutions

This recipe is wonderfully adaptable. For a dairy-free version, swap the Greek yogurt for coconut yogurt and use coconut oil instead of butter. If you’re out of almond flour, sunflower seed flour works as a nut-free alternative (though it may darken the cake slightly). For a different fruit twist, try raspberries or blackberries instead of blueberries. If you’re not strictly low-carb, a drizzle of honey or a dusting of powdered sugar adds a lovely finish. You can even turn this into muffins by dividing the batter into a lined muffin tin and reducing the baking time to 20-25 minutes.

What to Serve With It

This cake shines on its own, but a few accompaniments can elevate it further. A dollop of whipped coconut cream adds a luxurious touch, while a side of fresh berries enhances the fruity flavors. For a brunch spread, pair it with herbal tea or iced lemon water to keep things light. If you’re serving it as dessert, a scoop of low-carb vanilla ice cream makes it feel extra indulgent. For a savory contrast, enjoy it alongside a cheese platter with sharp cheddar or creamy brie.

How to Store and Reheat

Store leftover cake in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. To freeze, wrap individual slices in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before serving. For a fresh-from-the-oven feel, warm slices in the microwave for 10-15 seconds or in a 300°F oven for 5 minutes. If the cake feels dry after storage, a quick brush of lemon juice or a light drizzle of sugar-free syrup can revive it.

Frequently Asked Questions (FAQs)

Can I use frozen blueberries instead of fresh? Yes, but keep them frozen until the last minute to prevent excess moisture. Toss them in almond flour to help them distribute evenly.

What sweetener works best for this recipe? Erythritol or monk fruit blends are ideal because they measure like sugar and don’t leave an aftertaste. Avoid liquid sweeteners unless you adjust the wet ingredients.

Why did my cake turn out dense? Overmixing the batter or using expired baking powder can cause denseness. Measure your almond flour correctly—don’t pack it into the cup.

Can I make this cake nut-free? Yes, sunflower seed flour is a great substitute, though it may give the cake a slightly greenish hue over time (harmless but unexpected).

How do I know when the cake is done? A toothpick inserted into the center should come out clean or with a few moist crumbs. The edges will pull away slightly from the pan.
