Recipe Tips
Use room temperature eggs and oat milk: Cold ingredients can lead to uneven mixing. Bringing eggs and milk to room temperature ensures a smoother batter and more even bake.
Avoid overmixing: Almond flour and protein powder are delicate. Overmixing can lead to dense, rubbery muffins. Stir just until there are no visible streaks of dry flour.
Adjust sweetness to taste: The flavor and sweetness level of protein powders vary significantly. Make sure you enjoy the taste of yours before using it, and adjust the honey accordingly if your powder is already sweetened.
Watch the bake time: Almond flour can brown quickly and protein-based baked goods can dry out quickly. Start checking for doneness around 17 minutes. A toothpick should come out clean or with just a few moist crumbs.
Cool completely before glazing: Applying glaze to warm muffins will cause it to melt and run off. Wait until the muffins are fully cool so the glaze can set nicely on top.
Glaze customization: The almond butter glaze can be adjusted to your taste. You can add vanilla extract, a pinch of salt, or swap the honey with maple syrup for a different flavor profile.
Ingredients You Need for Lemon Poppy Seed Protein Muffins
For the Muffins
- Almond flour provides a moist, tender texture and adds healthy fats and a subtle nutty flavor, serving as the base flour in this gluten-free recipe.
- Vanilla protein powder boosts the protein content while contributing structure and subtle sweetness to the muffins.
- Poppy seeds add a delicate crunch and a classic visual and flavor element to complement the lemon.
- Baking powder acts as a leavening agent, helping the muffins rise and achieve a light, fluffy texture.
- Salt enhances the overall flavor and balances the sweetness in the batter.
- Eggs provide structure, moisture, and help bind all the ingredients together, while also contributing to the muffins rise.
- Unsweetened oat milk adds moisture and helps blend the dry ingredients smoothly without overpowering flavors.
- Fresh lemon juice brings a bright, tangy flavor that defines the lemon profile of the muffins and reacts with the baking powder for additional lift.
- Lemon zest intensifies the lemon flavor with fragrant citrus oils, adding depth and freshness.
- Honey naturally sweetens the muffins while also adding moisture and aiding in browning.
- Vanilla extract rounds out the flavor with a warm, aromatic note that enhances both the lemon and honey.
- Grapeseed oil provides richness and moisture while keeping the muffins tender without overpowering the other flavors.
For the Glaze
- Fresh lemon juice adds a tart, vibrant element that enhances the lemon flavor and balances the sweetness of the glaze.
- Almond butter gives the glaze a creamy consistency and nutty richness while helping it adhere to the muffins.
- Honey sweetens the glaze naturally and adds shine and stickiness for an appealing finish.
- Zest of 1 lemon (for garnish) adds a final burst of color, aroma, and citrus flavor to enhance the muffins presentation and freshness.
Directions – How to Make Lemon Poppy Seed Protein Muffins
Preheat the oven to 175°C (350°F) and line a 12-cup muffin pan with cupcake liners. In a large bowl, whisk together the almond flour, protein powder, poppy seeds, baking powder, and salt.
In a separate medium bowl, whisk the eggs, oat milk, lemon juice, lemon zest, honey, vanilla extract, and grapeseed oil until well combined.
Pour the wet mixture into the dry ingredients and stir with a silicone spatula until just combined — avoid overmixing. Divide the batter evenly among the muffin cups, filling each about ¾ full.
Bake on the middle rack for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Let the muffins cool completely on a wire rack before adding the glaze. In a small bowl, whisk together almond butter, lemon juice, and honey until smooth.
Drizzle the glaze over the cooled muffins and top with lemon zest, if desired. Enjoy!
Storing and Freezing Instructions
Storing: Store the muffins in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days to maintain freshness. For best texture, allow chilled muffins to come to room temperature before serving.
Freezing: To freeze, place the completely cooled muffins (unglazed or glazed) in a single layer in an airtight container or ziplock bag. If glazing before freezing, let the glaze fully set. Separate layers with parchment paper to prevent sticking. Freeze for up to 3 months.
Thawing: To thaw, remove muffins from the freezer and let them sit at room temperature for about 1–2 hours, or reheat gently in the microwave for 20–30 seconds. If unglazed, you can add fresh glaze after thawing.
