Mix the 3 3-oz pkgs of cream cheese w/3 tbsp powdered sugar till well-combined & smooth. Divide mixture into 3 equal portions in separate bowls.
Add 3 tbsp strawberry preserves to the 1st bowl & mix well. Add 3 tbsp blueberry preserves to the 2nd bowl & mix well. Cut 1/3 of the banana into sml pieces, add to the 3rd bowl & mash into cream cheese mixture till fully incorporated & smooth.
“Eyeball” the strawberry & blueberry mixtures for desired color. If a darker color is desired, add food coloring 1 drop at a time till you’re happy w/the color. Set all 3 bowls aside.
In a somewhat larger bowl, mix the 8-oz pkg of cream cheese w/3 tbsp powdered sugar till well-combined & smooth. Cut the remaining 2/3 of the banana in sml pieces, add & mash into cream cheese mixture till fully incorporated & smooth. Set this bowl aside for use toward the end.
Assembly: Put 1 tortilla on your work surface & spread the strawberry & cream cheese mixture over the tortilla. Place a 2nd tortilla on top of the 1st & spread the sml banana & cream cheese mixture over the tortilla. Place a 3rd tortilla on top of the 2nd & spread the blueberry mixture over the tortilla. Put the last tortilla on top, cover w/plastic wrap & refrigerate for at least 1 hours.
Remove from refrigerator. Using the contents of the larger bowl mixture of cream cheese, sugar & banana, now “frost” the tortilla stack as you would a cake (top & sides). Cover w/plastic wrap & refrigerate for at least 1 hr or put in your freezer for at least 30 minute This will firm up the cream cheese & better allow for easy slicing.
Remove from refrigerator or freezer. Using a very sharp knife, carefully cut into 8 wedges as you would a pie, but leave the wedges in place. Garnish the top portion of the cut wedges w/fresh strawberry segments & fresh blueberries as desired &/or sprinkle with ¼ cup crushed red & blue M&M’s to please the kids.
Cover & refrigerate till ready to serve surrounded by additional fresh fruit & a dish of cool whip on the side -- maybe even more of the M&M's.
NOTE: Makes a 3-layer cake w/top to frost & garnish w/fresh fruit, but the layers are tortillas. You can add fruit to the layers (if adventurous) or repeat the layering process to 6 layers w/top. I've always felt the smaller serving w/fresh fruit was the best option.
