Whole Wheat–Oat Waffles

Directions

1. 1.

   Bring lemon zest, sugar, and ⅔ cup water to a boil in a heavy medium saucepan, stirring until sugar dissolves. Cook (do not stir) until a thin syrup forms, 6–8 minutes. Add blueberries and bring to a simmer. Reduce heat to medium; cook, stirring constantly, 2 minutes.

2. 2.

   Transfer 2 Tbsp. syrup to a small bowl, add cornstarch, and stir until smooth. Add back to syrup; simmer until thickened, about 1 minute. Remove from heat. Fish out lemon zest and discard. Squeeze in lemon juice to taste and let cool slightly.

3. 3.

   Whisk flour, oats, baking powder, baking soda, and salt in a large bowl. Make a well in the center and add yogurt, then melted butter, then egg to well. Using a fork, stir together wet ingredients, then mix, incorporating dry ingredients a little at a time, until a lumpy batter forms.

4. 4.

   Heat waffle iron on medium-low. Lightly coat with nonstick spray and pour a heaping ½ cup batter onto iron (or up to 2 cups if using a larger one). Cook until waffles are golden brown and cooked through, about 5 minutes. (Keep warm on a baking sheet in a 300° oven if desired.) Repeat with remaining batter, coating iron with more nonstick spray as needed. Serve with butter and warm syrup.
