Instructions

  1. Step 1: Preheat oven to 350°F and line a muffin tin with paper liners. In a bowl, mix oats, flour, baking powder, and lemon zest until combined.
  2. Step 2: In another bowl, mash blueberries with a fork until mostly broken down, then stir in honey, melted coconut oil, and 1/4 cup water until well blended.
  3. Step 3: Add blueberry mixture to dry ingredients and gently fold until just combined, being careful not to overmix.
  4. Step 4: Divide batter evenly into 12 muffin cups (about 1/3 cup each). For the streusel, mix almond flour, rolled oats, and 1 tbsp melted coconut oil until crumbly, then sprinkle over muffin tops.
  5. Step 5: Bake for 20-22 minutes until golden brown and a toothpick inserted comes out clean. Cool in pan for 5 minutes before transferring to a wire rack.

How do I store leftover Lemon Blueberry Oatmeal Muffins with Almond Streusel?

Can I substitute ingredients in Lemon Blueberry Oatmeal Muffins with Almond Streusel?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Lemon Blueberry Oatmeal Muffins with Almond Streusel for a different number of people?

The recipe is written for 12 servings. Multiply each ingredient by (your serving target / 12). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
