Step‑by‑Step Instructions for Blueberry Oatmeal Breakfast Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it’s warming, line an 8″x8″ baking pan with parchment paper, ensuring the paper overlaps the edges for easy removal later. This step makes clean-up a breeze and helps the bars come out perfectly intact once baked.
Step 2: Combine Dry Ingredients
In a large mixing bowl, combine rolled oats with almond meal, if using. Stir thoroughly to ensure the dry ingredients are evenly mixed. This provides a solid base for your Blueberry Oatmeal Breakfast Bars. Keep an eye out for clumps; breaking them up will help your bars bake evenly.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together honey (or maple syrup), nut butter, and egg until smooth and well blended. The mixture should be slightly glossy and thick. This creates the moisture that binds the ingredients together, ensuring your bars are deliciously chewy.
Step 4: Combine Mixtures
Pour the wet mixture into the bowl with the dry ingredients. Mix gently until just combined, being careful not to overmix; this will keep the texture light. The batter should look cohesive, with no dry oats remaining.
Step 5: Fold in Blueberries and Lemon Zest
Gently fold in the blueberries and lemon zest, if using, to the batter. Make sure the blueberries are evenly distributed without smashing them. You’ll want bursts of berry flavor in every bite of your Blueberry Oatmeal Breakfast Bars, adding to the taste and nutrition.
Step 6: Transfer to Baking Pan
Once everything is well combined, pour the batter into your prepared baking pan. With a spatula, spread the mixture evenly, pressing down gently so it spreads out well. This ensures uniform thickness for even baking, which is key for perfect breakfast bars.
Step 7: Bake
Place the pan in your preheated oven and bake for 35-40 minutes. Keep an eye on it, and look for the edges to turn golden brown while the center sets. A toothpick inserted in the center should come out with a few moist crumbs, signaling that your bars are ready.
Step 8: Cool and Slice
After baking, let the bars cool in the pan for about 10 minutes to firm up. Then, carefully transfer them to a wire rack to cool completely. Allowing them to cool fully before cutting will result in cleaner edges and more structurally sound Blueberry Oatmeal Breakfast Bars.
Step 9: Cut and Store
Once cooled, slice the bars into 12 even pieces. Store any leftovers in an airtight container at room temperature for up to three days, or refrigerate for up to a week. Enjoy these nutritious treats throughout the week for breakfast or snacks!
