Protein Cereal Ingredients • For the Cereal Base All-Purpose Flour – Provides structure and texture; substitute with oat flour for a gluten-free option. Almond Flour – Increases protein content; can replace with more all-purpose flour if allergic to nuts. Protein Powder – Adds strength to your morning meal, using whey protein for the best results, or substitute with flour if you prefer no protein powder. Granulated Sugar Substitute – Sweetens your protein cereal while keeping calories low; regular sugar can be used but will increase calorie count to 200 per serving. Cinnamon – Infuses warm, comforting flavor; no substitutions needed, just sprinkle generously! Salt – Enhances all the flavors; use standard table salt for best results. Milk – Brings the dry ingredients together into a lovely dough; any type works, but almond or 2% milk is highly recommended. • For the Topping Cinnamon Sugar Mixture – A sprinkle on top provides that classic Cinnamon Toast Crunch flavor; mix sugar and cinnamon to taste! With these ingredients, you’ll be on your way to creating a delightful homemade protein cereal that’s not only delicious but also supports your health goals! Step‑by‑Step Instructions for Homemade High-Protein Cinnamon Toast Crunch Cereal Step 1: Preheat the Oven Start by preheating your oven to 350°F (175°C). This ensures a perfectly crunchy finish for your protein cereal. While the oven warms up, gather your mixing bowls and baking sheets, so you’re ready to create this delicious cinnamon-infused breakfast. Step 2: Mix Dry Ingredients In a large mixing bowl, combine the all-purpose flour, almond flour, protein powder, granulated sugar substitute, cinnamon, and salt. Use a whisk to blend these dry ingredients thoroughly for about 1-2 minutes, ensuring even distribution. This step is crucial as it sets up the flavor profile for your high-protein cinnamon toast crunch. Step 3: Add Milk Gradually Slowly add milk to the dry mixture, one tablespoon at a time, while mixing with a spatula or your hands. Continue this process until a workable dough forms, which should take about 5-6 tablespoons, depending on your protein powder. The dough should be slightly sticky but manageable, perfect for shaping into a cereal. Step 4: Chill the Dough Once your dough is ready, wrap it in plastic wrap and refrigerate for 30 to 60 minutes. Chilling the dough makes it easier to roll out and helps prevent sticking. Use this time to clean up your workspace and prepare your parchment paper for the next steps. Step 5: Roll Out the Dough After the chilling period, take the dough out and place it between two sheets of parchment paper. Roll it out into a thin layer, about 1/8 inch thick, using a rolling pin. The thinner the dough, the crunchier your homemade protein cereal will be, so make sure to apply even pressure. Step 6: Prepare for Baking Lightly spray the rolled-out dough’s surface with cooking spray, then mix together some cinnamon and sugar substitute. Sprinkle this mixture evenly on top, pressing it down gently with your hands. This step enhances the sweetness and ensures your protein cereal captures that iconic Cinnamon Toast Crunch flavor. Step 7: Cut into Pieces Using a pizza cutter or a sharp knife, cut the dough into cereal-sized squares or rectangles. The size you choose affects the crunchiness of your protein cereal, so feel free to experiment! Make sure the sections are roughly uniform for even baking, helping them achieve that perfect texture. Step 8: Bake the Cereal Transfer the cut pieces onto a parchment-lined baking sheet, spacing them slightly apart. Bake in your preheated oven for 16-18 minutes, until they turn golden brown around the edges. Keep an eye on them towards the end to avoid over-baking, as the color will be your cue for doneness. Step 9: Cool and Break Apart Once baked, remove the protein cereal from the oven and let it cool completely on the baking sheet for about 30 minutes. This cooling period is essential as it allows the pieces to crisp up further; then break apart along the cuts. Enjoy your homemade protein cereal right away or store it for later! Expert Tips for Protein Cereal Consistent Dough Texture: Ensure your dough is slightly sticky but manageable. Adjust the milk quantity based on the protein powder type to create the perfect consistency. Don’t Over-Bake: Keep an eye on your protein cereal towards the end of the baking time. Over-baking can lead to a hard texture rather than the desired crunchiness. Use Parchment Paper: Place a layer of parchment paper on your baking sheet to help prevent any sticking, especially while rolling out the dough and during baking. Experiment with Flavors: Feel free to switch up the protein powder flavor to match your preferences, such as chocolate or vanilla, adding a delightful twist to the classic protein cereal. Uniform Cutting: Cut your dough into even-sized pieces to ensure that each piece bakes evenly. This way, you’ll enjoy a consistent crunch across your homemade protein cereal. Cooling Time Matters: Let the cereal cool completely after baking for the best texture. This waiting period is crucial for achieving optimal crunchiness.
