Ingredients

Base Ingredients

  • 1 cup Old fashioned oats Quick oats work in a pinch, but the texture is softer.
  • 1/2 cup All-purpose flour
  • 1/3 cup Light brown sugar White sugar can be used instead.
  • 1 teaspoon Baking powder
  • 1/4 teaspoon Salt
  • 1/4 cup Unsalted butter, melted Coconut oil can work too.
  • 1 large Egg yolk Helps bind without making a big batch.
  • 1 tablespoon Lemon zest
  • 2 tablespoons Lemon juice Fresh is best, but bottled works.
  • 1 cup Blackberries Fresh or frozen. Do not thaw if frozen.
  • 1 teaspoon Vanilla extract Optional.

Instructions

Preparation

  • Preheat your oven to 350°F (175°C) and grease or line your loaf pan or 8x8 pan.
  • In a medium bowl, mix together oats, flour, sugar, baking powder, and salt.
  • In another bowl, whisk together melted butter, egg yolk, lemon zest, lemon juice, and vanilla (if using).
  • Combine the wet ingredients into the dry ingredients until just mixed.
  • Fold in the blackberries gently.

Baking

  • Pour the mixture into the prepared pan and spread evenly.
  • Bake for 25-30 minutes, or until the edges are golden and the center looks set.
  • Let cool fully in the pan before slicing.

Notes

These bars can be stored on the counter for 1-2 days or in the fridge for up to 5 days. For longer storage, freeze for up to 2 months. Bake a batch, cool completely, slice, and then freeze half to avoid overeating.
