    Preparation and Cooking Overview

    This recipe comes together in about 10 minutes of prep time and 20-25 minutes of baking. Mix the dry and wet ingredients separately, fold in juicy blueberries, and bake until golden brown. The result? Moist, fluffy, and perfectly sweet muffins—without the carbs.

    Chef's note

    For an extra pop of flavor, add a teaspoon of lemon zest to the batter. If using frozen blueberries, toss them in a little almond flour before mixing to prevent sinking. You can also swap vanilla extract for almond extract or add a teaspoon of cinnamon for a twist. For a crunchier topping, sprinkle crushed nuts or a keto-friendly streusel before baking.

    Ingredients for Keto Blueberry Muffins

    • 2 cups almond flour
    • ¼ cup coconut flour
    • ½ cup granulated erythritol
    • 1 teaspoon baking powder
    • ¼ teaspoon salt
    • 3 large eggs
    • ½ cup unsweetened almond milk
    • ¼ cup melted butter
    • 1 teaspoon vanilla extract
    • 1 cup fresh blueberries (or frozen, tossed in almond flour)
    • 1 teaspoon lemon zest (optional)

    Ingredient Substitutions

    • Almond flour: Swap it with sunflower seed flour for a nut-free option.
    • Erythritol: You can replace it with monk fruit sweetener or stevia.
    • Butter: Use coconut oil for a dairy-free version instead of butter.
    • Blueberries: Raspberries or blackberries can be swapped in to add variety to the muffins.

    Cooking Toos Required

    • Whisk
    • Muffin tin (12-count)
    • Muffin liners or silicone molds
    • Measuring cups and spoons
    • Rubber spatula

    Tool Substitute Options

    • Muffin tin: Use silicone muffin molds or bake in a small loaf pan instead.

    How to Make Keto Blueberry Muffins: Step-by-Step Guide

    Cooking Methods

    • Baking

    Preparation Steps

    1. Preheat oven to 350°F (175°C).
    2. Line a muffin tin with parchment paper muffin liners or lightly grease with butter.

    Cooking Instructions

    1. In a large bowl, whisk together almond flour, coconut flour, erythritol, baking powder, and salt.
    2. In a separate bowl, whisk eggs, almond milk, melted butter, and vanilla extract.
    3. Gradually add the wet ingredients to the dry ingredients, stirring until well combined.
    4. Fold in blueberries gently with a rubber spatula to prevent crushing.
    5. Fill muffin cups about ¾ full with batter.
    6. Bake for 20-25 minutes or until the tops turn golden brown and a toothpick inserted in the center comes out clean.
    7. Cool for 10 minutes in the pan, then transfer to a wire rack to cool completely.

    Chef's pro tip

    Overmixing the batter can lead to dense muffins instead of a light, fluffy texture. To avoid this, gently stir the wet and dry ingredients until just combined—it’s okay if the batter looks slightly lumpy. Also, ensure your blueberries are folded in carefully to prevent breaking and turning the batter purple.

    What to Serve with Keto Blueberry Muffins

    These muffins pair perfectly with:

    • Keto Coffee: A warm cup of coffee enhances the rich flavors of the muffins and balances their sweetness with a hint of bitterness.
    • Keto yogurt: A bowl of unsweetened keto yogurt complements the muffins with its creamy texture and slight tanginess.
    • Whipped cream: A dollop of freshly whipped cream adds a light, creamy texture that pairs perfectly with soft, fruity muffins.
    • Keto Smoothie: A refreshing keto smoothie with almond milk and avocado creates a balanced meal with a mix of flavors and textures.

    How to Make It Healthier

    • Use coconut oil instead of butter for a dairy-free option.
    • Add a tablespoon of chia seeds or flaxseeds for extra fiber.

    Time-Saving Tips

    • Use frozen blueberries—no need to thaw, just toss them in almond flour before mixing.

    What Can I Prepare Ahead of Time?

    • Pre-mix dry ingredients ahead of time and store in an airtight container for quick preparation.
    • Batter can be mixed up to 4 hours ahead and stored in the fridge.
    • Grate lemon zest in advance and freeze it for future use.

    Storage and Reheating Instructions

    Storage Instructions

    • Fridge: Store the muffins in an airtight container to keep them fresh for up to 5 days.
    • Freezer: You can place the muffins in a freezer-safe bag for up to 3 months.

    Best Reheating Instructions

    • Microwave: Heat the muffin for 15-20 seconds for a warm muffin.
    • Oven: Reheat at 300°F (150°C) for 5-7 minutes for a fresh-baked texture.
