20g Matcha Latte Protein Shake

20g Matcha Latte Protein Shake

Baked oatmeal is a breakfast that practically makes itself: mix, pour, bake, and you have a week of portions ready. But if you want more protein without the chalky taste of protein powder, a ready-to-drink shake can do the job more smoothly. REBBL 20g Matcha Latte Protein Shake brings 20 grams of plant protein, a gentle matcha lift, and Lion's Mane mushroom extract to support cognitive function, making it a smart swap for the liquid in your oatmeal bake.

This guide walks you through the process step by step, with the common mistakes that can turn a good bake into a dry or overly sweet block. You'll also learn how to adjust sweetness, balance the matcha flavor, and store your baked oatmeal so it stays moist for days.

Why Use a Protein Shake in Baked Oatmeal?

Using a ready-to-drink shake instead of milk or water adds protein without the clumping that often happens with protein powder. REBBL 20g Matcha Latte Protein Shake contains 20 grams of plant-based protein, making it a convenient base that also contributes flavor and a subtle caffeine boost from naturally occurring matcha.

The shake also includes Lion's Mane mushroom extract, which is included for cognitive support. That means your breakfast can do more than just fill you up. Just keep in mind that the shake is sweetened, so you'll want to reduce or skip added sugar in your recipe to avoid an overly sweet bake.

  • Use the shake as a 1:1 replacement for milk or water in your standard baked oatmeal recipe.
  • Taste the batter before baking; if it's already sweet enough, cut the sweetener in half.

Choosing the Right Oats and Add-Ins

Old-fashioned rolled oats are the best choice for baked oatmeal because they absorb liquid without turning mushy. Steel-cut oats will stay too chewy, and instant oats can become pasty. For a 20-gram protein boost, the shake does the heavy lifting, so you can keep the rest of the ingredients simple.

Matcha pairs well with vanilla, white chocolate chips, sliced almonds, or a sprinkle of sesame seeds. Avoid strong citrus or mint, which can clash with the earthy matcha flavor. If you want extra protein, a spoonful of nut butter stirred into the batter works well and adds healthy fats.

  • Stick with old-fashioned rolled oats for the best texture.
  • Fold in white chocolate chips or almonds after mixing the batter.

Adjusting Sweetness and Flavor

REBBL 20g Matcha Latte Protein Shake is already sweetened, so you need to taste your batter and adjust. A good starting point is to use only half the sugar your usual recipe calls for, then add more only if needed. You can also rely on mashed banana or unsweetened applesauce for natural sweetness and moisture.

The matcha flavor is present but not overpowering, so you can add a little extra matcha powder if you want a stronger green tea taste. Just be careful: too much matcha can make the bake bitter. Start with a quarter teaspoon and taste the batter before baking.

  • Use half the sweetener your recipe calls for, then adjust to taste.
  • Add extra matcha powder sparingly to avoid bitterness.

Step-by-Step: Baked Oatmeal with Matcha Protein Shake

  1. Preheat and prep your pan: Preheat your oven to 350°F (175°C). Grease an 8x8-inch baking dish or line it with parchment paper so the oatmeal doesn't stick. Checkpoint: If you skip greasing, the edges will be hard to remove cleanly.
  2. Mix the dry ingredients: In a bowl, combine 2 cups old-fashioned rolled oats, 1 teaspoon baking powder, a pinch of salt, and any spices like cinnamon or nutmeg. Whisk to distribute evenly. Checkpoint: Make sure baking powder is fresh; otherwise the bake won't rise properly.
  3. Combine the wet ingredients: In a separate bowl, whisk 1 bottle (or 1 cup) of REBBL 20g Matcha Latte Protein Shake, 1 large egg (or flax egg), 1 tablespoon melted coconut oil or butter, and 1 teaspoon vanilla extract. If you want extra sweetness, add 1-2 tablespoons maple syrup or honey, but taste first. Checkpoint: Taste the wet mixture. If it's already sweet enough, skip the added sweetener.
  4. Fold wet into dry: Pour the wet mixture into the dry ingredients and stir until just combined. Do not overmix; a few lumps are fine. Fold in optional add-ins like white chocolate chips or sliced almonds. Checkpoint: Overmixing can make the oatmeal tough. Stop when the oats are coated.
  5. Bake and cool: Pour the batter into the prepared dish and smooth the top. Bake for 30-35 minutes, until the top is golden and a toothpick inserted in the center comes out mostly clean. Let it cool for 10 minutes before slicing. Checkpoint: If the top browns too quickly, cover loosely with foil for the last 10 minutes.
  6. Store and reheat: Store leftovers in an airtight container in the fridge for up to 5 days. To reheat, microwave a portion for 30-60 seconds or warm in a toaster oven. You can also freeze individual portions for up to 3 months. Checkpoint: Add a splash of milk or extra shake when reheating if the oatmeal seems dry.
