Step by Step Instructions
Step 1: Preheat oven to 350°F (180°C). Line a slice pan (approx. 8×12 inch) or square baking pan with parchment paper.
Step 2: Mix dry ingredients: In a large mixing bowl, add the cornflakes and crush with the base of your cup. Add gluten-free flour (and baking powder if substituting), coconut, cocoa, and brown sugar.
Step 3: Melt butter: In a small saucepan over low heat, or in the microwave, melt the butter. Remove from heat, stir in maple syrup and vanilla extract.
Step 4: Combine: Pour the wet mixture into the dry ingredients and mix well until fully combined.
Step 5: Press the mixture evenly into the prepared pan. Bake for 22–25 minutes or until set and lightly golden.
Step 6: Cool & Ice: Let cool completely in the pan. Spread with chocolate icing (recipe below) and sprinkle with extra coconut if desired. Slice into bars or squares.
🧊 Storage Tips
