Step-by-Step Guide
Follow these detailed instructions for perfect bars every time.
- Preheat and Prepare: Begin by preheating your oven to 300°F (150°C). Lightly coat an 8-inch square baking pan with nonstick cooking spray. For easy removal, you can also line it with parchment paper, leaving an overhang on two sides.
- Combine Dry Ingredients: In a medium bowl, whisk together the instant oats, whole wheat flour, baking powder, ground cinnamon, and salt. Ensure they are evenly distributed.
- Mix Wet Ingredients: In a separate, larger bowl, whisk the egg white until slightly frothy. Add the vanilla extract, creamy peanut butter, pure maple syrup, and unsweetened vanilla almond milk. Whisk vigorously until the mixture is smooth and fully combined. The peanut butter should be fully incorporated with no lumps.
- Combine Wet and Dry: Pour the dry ingredient mixture into the bowl with the wet ingredients. Use a spatula to fold and stir until just combined. Be careful not to overmix; the batter will be thick.
- Press into Pan: Transfer the batter to your prepared pan. Use the spatula or your fingers (lightly dampened with water to prevent sticking) to press the mixture into an even, compact layer across the entire pan.
- Bake and Cool: Bake for 10-12 minutes. The bars are done when the edges are lightly golden and the center appears set. Do not overbake, as they will continue to firm up as they cool. Let the pan cool completely on a wire rack before slicing into bars.
Serving Suggestions
These versatile bars are delicious on their own but can be elevated for different occasions. For a breakfast boost, serve a bar with a side of Greek yogurt and fresh berries. As an afternoon snack, pair it with a glass of cold milk or a cup of coffee. For a dessert-like treat, warm a bar slightly and top with a dollop of whipped cream or a drizzle of melted dark chocolate. They also pack perfectly for hikes, lunchboxes, or post-workout fuel.
How-to Summary
In short: Whisk dry ingredients. Whisk wet ingredients separately. Combine them, press into a prepared pan, and bake at 300°F for 10-12 minutes. Cool completely before slicing into bars.
Frequently Asked Questions
- Can I use old-fashioned oats instead of instant? Yes, but the texture will be chewier and more distinct. Instant oats blend more seamlessly, creating a denser, more uniform bar.
- How do I make these gluten-free? Simply replace the whole wheat flour with a 1:1 gluten-free all-purpose flour blend and ensure your oats are certified gluten-free.
- Can I use a different nut butter? Absolutely. Almond butter or sunflower seed butter are excellent substitutes and will alter the flavor profile slightly.
- How should I store these bars? Store cooled bars in an airtight container at room temperature for 2-3 days, in the refrigerator for up to a week, or freeze for up to 3 months.
- Why is my batter so thick/dry? This is normal! The batter is meant to be very thick so the bars hold their shape. If it seems excessively dry and crumbly, add one additional tablespoon of almond milk.
Common Mistakes to Avoid
- Overbaking: This is the top mistake. Baking beyond 12 minutes can dry out the bars. They will firm up significantly as they cool.
- Slicing While Warm: Cutting before the bars are completely cooled will cause them to crumble. Patience is key for clean slices.
- Overmixing the Batter: Stir just until the flour disappears. Overmixing can lead to tough, dense bars.
- Using Cold Peanut Butter: If your peanut butter is stiff from the fridge, warm it slightly for easier mixing and a smoother batter.
